Calculation of the size of the furnace for a long-burning boiler on firewood

The type of wood, shape and length of firewood determines the size and equivalent area of ​​the heat chamber. Specific and volumetric loading density, heat that firewood is isolated during combustion - reference values. The cost calculation will help calculate fuel consumption per season, organize fuel storage locations.

Important! The quality of firewood affects the combustion process. The large content of resins in the wood of coniferous rocks and high humidity of freshly dredged wood reduces the CPD of the boiler. The incomplete combustion of raw wood leads to the deposition of soot and resin on the surface of the water circuit, the walls of the furnace and chimney. Metal is oxidized, worse transfers heat, quickly goes.

Table 3. Volumetric heat combustion of wood of different breeds:

Type of wood (humidity no more than 20%) Calorific value, kWh / kg Specific density of firewood, kg / m³ Bulk density, kg / dm³ Combustion temperature, ° С
spruce 4.3. 450. 1,4. 600.
Pine ordinary 4.3. 520. 1,6 660.
Birch tree 4,2 650. 1.9 890.
oak 4,2 720. 2.0 900.

Consider an example of calculating the volume of the loading chamber of the wood boiler. Increased data:

  • 10 kW boiler power;
  • The volume of one download should ensure the operation of the unit during the day;
  • Fuel - Birch Firewood, Length Length 0.60 ÷ 0.65 m;
  • Wood humidity 20%.

Varianty-Otopleniya-Zagorodnogo-Doma-1mOptions for the heating of a country house: the choice of the boiler. The advantages and disadvantages of water heating from the furnace on firewood. Features of solid fuel, gas, electrical units: description and prices.

With a combustion of 1 kg of birch wood, 4.2 kW of thermal energy is distinguished. The predetermined power (10 kW) will ensure combustion of 2.4 kg of firewood per hour (10/4.2 = 2.381).

The cubic meter of birch firewood weighs 650 kg. An hourly fuel consumption will be ≈ 0.004 m³ / h (2.4 / 650 = 0.0037).

The weight of the bookmark, which should withstand a grate with a nozzle ≈ 60 kg (2.381x24 = 57,144).

Birch Firewood Looks loosely, so the bookmark volume will increase by 1.9 times - to 0.008 m³ / h (0.004x1,9 = 0.0076).

By condition - loading 1 time in 24 hours, respectively, the fuel volume is 0.2 m³ (0.008x24 = 0.192).

Homemade solid fuel boilers are inexpensive heat sources where there are still no gas lines. Burning in its firewood firewood, they allocate a large amount of thermal energy that is consistent with the heating of residential premises. But they require constant attention of users, which is associated with rapid fuel combustion. Let's see how the boilers of long burning on firewood are harvested with their own hands with a download for 24 hours, which do not require frequent loading of fuel.

In this review we will look at:

  • The main features of wood boilers;
  • Principles for the implementation of long burning;
  • Varieties of long-burning boilers working on firewood;
  • Instructions for self-assembly.

After reading this review, you can decide which boiler can be collected with your own hands.

Heating Firewood - Pros and Cons

Homemade wood boilers are actively used to heat residential premises - these are small country houses and large private households located in places far from gas highways. Firewood or stone coal is used as fuel. Coal aggregates are distinguished by high heat dissipation, but it is not always possible to get this fuel. Therefore, people prefer wood models.

Let's consider the main advantages of homemade boilers on firewood:

  • No need to install and operate - we have the right to independently dispose of these equipment;
  • The cheapness in operation - compared with electric heating, heated firewood cheapest. And if you find a source of free flights, it will remain spent only on the assembly of the heating boiler;
  • Independence from the power grid - this refers to the simplest aggregates, which contains electrical components;
  • The possibility of realizing long burning - it will reduce the number of approaches to bookmark all new portions of fuel;
  • The cheapness in the assembly is the homemade boiler on firewood for a private house will cost cheaper than its factory analogue.

There are some drawbacks:

Cleaning the boiler from ash

Only the constant cleaning of the boiler and its systematic planned repairs will be able to provide stable and efficient operation of the unit throughout its operation.

  • Homemade wood heating boilers at home may not go to the maximum efficiency - the mistakes of the handicraft assembly affect;
  • Boilers on solid fuel on the corner and firewood require regular cleaning - that is, we can get rid of the need for frequent bunch of fuel, but it is impossible to cope with the problem of cleaning. Therefore, we will have to regularly clean the equipment from soot and ash;
  • The complexity of self-installation - homemade boilers of long burning on firewood, with water contour, may seem complex in the manufacture. And the less experience with the tools, the more difficult task will seem.

In addition, homemade long-burning boilers are not distinguished by normal external data, although it all depends on the skill of the collector.

In addition to soot and coals, condensate can be formed in the long burning boilers - it is formed as a result of using raw wood.

Ways to implement long burning

The main problem pursuing users of boilers on firewood is the lack of long burning. We have to regularly throw all new portions of firewood in their furnaces. And if in the afternoon you can somehow come true with this, then at night the problem is exacerbated - if you do not pay due attention to the equipment, then the fuel will get out. An hour after attenuation, the temperature in the rooms will start falling.

This problem can be solved rather interesting way - to build an electric heater (TEN) into the boiler on firewood. We can't get long burning here, but the TEN will be able to maintain a certain temperature in the circuit, providing users with warmth. True, this approach is fraught with a large electricity consumption - in a month can "naughty" up to several thousand rubles, depending on the area of ​​home ownership and the power of the Tan itself.

Solid fuel boilers of long burning, working on firewood and coal, completely solve the problem with frequent loading of fuel. Some of them can burn up to several days, providing consumers with warmth. Long burning is implemented in several ways:

  • An increase in the combustion chamber of several times;
  • Use of the pyrolysis combustion scheme;
  • By partial automation of fuel supply.

Let's see what will give us the use of certain techniques.

Increase the combustion chamber

Homemade boiler combustion chamber

Correctly calculating the size of the combustion chamber and the doors for feeding firewood, you will not only increase the efficiency of the boiler, but also substantially facilitate life yourself during its operation.

The easiest way to implement long-term burning in the boiler on firewood is to increase its combustion chamber. Suppose we need to warm up a household area of ​​100 square meters. For this, we need 2.3 firewood per hour (the average wood caloriness is about 4.3 kWh / kg. Consequently, in order to achieve long burning over 12 hours, we will need a combustion chamber, which holds 28 kg of firewood. at the average Wood densities in 1.73 kg / dm³, the approximate volume of the chamber will be 16,18 liters.

Since we are interested in loading for 24 hours, the volume of the combustion chamber will be 32.26 liters. But you need to consider that firewood is not water. They do not occupy the entire space of the entire one, so you can morely multiply the obtained value for two - it turns out about 65 liters. It is also necessary to leave the reserve to normal burning so that it was where to freeze the flame, although everything depends on the boiler device.

By calculating the size of the combustion chamber, focus on the length of the lane - this will help create a comfortable firebox.

It becomes obvious that in order to implement super comprehensive burning, it is necessary to create a very large combustion chamber. And in order to further increase the efficiency and duration of the combustion of one portion of fuel, you should use certain varieties of wood - we recommend making a choice in favor of birch and oak. Despite the fact that the calorific value is less than that of the same pine, these trees are more dense. And they burn at higher temperatures (almost +900 degrees).

Pyrolysis burning

Pyrolysis of long-burning boilers make it possible to increase the combustion efficiency of firewood. Here are their principle of operation:

  • Fuel combines in the main combustion chamber with a minimum amount of oxygen;
  • Pyrolysis products that are distinguished as a result of such combustion enter the afterburning chamber;
  • In the combustion chamber, pyrolysis gases are combustion with highlighting a large amount of heat.

Next, thermal energy is selected by the frozen heat exchanger.

Fan and control unit of Polish production

A powerful fan and control unit will free you from the need to constantly adjust the combustion process, and besides the boiler will allow the boiler to work with much more efficiency.

The main advantage of pyrolysis is the possibility of realizing long burning due to the adjustment of the intensity of the pyrolysis reaction. For this, the system is installed in the system. When it turns on, a high-temperature flame is formed in the afterburning chamber, the heat carrier warp begins . Once the automation will regite the achievement of a given temperature, the blowing fan will stop - the slow burning boiler will suspend its work, minimizing the cost of fuel.

The implementation of the pyrolysis combustion scheme in firewood boilers is rather complicated, but it allows you to achieve long burning and automatic temperature adjustment in the circuit. If you want to do without automation, the intensity will have to be adjusted manually, using the Sewberry dampers and pondered.

Automation of fuel supply

A similar principle of the implementation of long-term combustion is implemented in boilers working not on firewood, but on pellets. Fuel in them is served using auger and burned in a burner of a special design. By connecting the bunker of giant sizes, you can not approach the equipment for several days. If you want a boiler with a long burning up to 7 days, you should pay your attention to pellets.

At home, we can implement the following scheme - to buy a burner with automatic feed pellets, connecting the bulk bunker to it. But we have the challenge to create a long-term combustion boiler on firewood. Therefore, we will look at two schemes of partial automation of the supply of firewood - lower and upper combustion.

The bottom burning boiler provides long-term combustion of fuel. The flame is formed at the very bottom of the wood masonry, breaking into a separate chamber. As the firewood is combustion, falling down, automatically feeding into the burning area. This is how the aggregates of a mine type work. But in the upper combustion boilers, the flame burns on the surface of wood masonry - such a scheme is implemented in Polish boilers installation of the sling and in self-assembly furnaces of bunching boobs.

Basic varieties of homemade boilers

If you are going to make a long burning boiler with your own hands, then information from our review will be useful. In the following sections, we will tell how to make a heating unit of one or another design itself, we will give some easiest schemes, publish information about the most common boilers of long burning. Let's still pay attention to the last question.

It is time to consider the most relevant options for boilers of long burning, which we can collect do it yourself at home. All of them will eat firewood. As for coal, it is more complicated, and it leads to the emergence of large temperature loads on heating units. In the following sections, we will give drawings of solid fuel boilers of long-burning and give explanatory information.

Long burning mine boiler

Long burning mine boiler

We can make the easiest mine boiler with your own hands. It is implemented according to a scheme with lower burning. The basis of the unit is a spacious loading chamber, which is often called the mine. Possessing a vertical design, it allows you to accommodate a large amount of firewood. As they burn, they fall down, and the combustion products are sent through the grille in the ash bar.

If we take a look at the mine furnace scheme (boiler), then we will find that the flames are not at all in the mine, but in the next chamber, from where the heat obtained goes into the wood-tube heat exchanger. And the remains of thermal energy are sent to the chimney. The burning here is long and is determined by the mine - downloading a large number of firewood here, you can safely go to bed.

Scheme of pyrolysis boiler

Pyrolysis boiler

Let's see how the pyrolysis boiler is arranged and how to make this aggregate with your own hands. The easiest way to explain the principle of operation of this unit on the example of the burzhuyki. Here we see the bulk combustion chamber, which sells long burning. The resulting combustion products are sent to the afterburning chamber, which serves secondary air. As a result, a large amount of heat is formed. We can only retail the bourgeois with a winter-tube heat exchanger.

There are dozens of drawings of long-burning boilers on firewood, built on pyrolysis principle. They are distinguished by the location of the combustion and afterburning chambers, the presence and absence of blowing fans and automation, as well as methods for adjusting the intensity of the process of burning wood fuel. But in general, their principle of work is the same.

Scheme of Boiler Bunch

Furnaces Boilers Bunch

The bunch is a furnace, and its modification is a water-heating firing boiler with air supply from above, through the presser piston. We have repeatedly wrote about such furnaces in our reviews, now it's time to talk about aggregates with a heating contour. To implement the contour, we can use three schemes:

  • Install the heat exchanger to the chimney - the easiest option;
  • To build a solid water shirt around the boiler housing;
  • Obwing the body of the unit with pipes by which the coolant will circulate.

What scheme to choose is to solve you. By the way, the boilers are bunching, at the expense of spacious cameras, will help to realize a long burning duration up to 24 hours and even more.

Bunch of long burning boobs work on firewood, they implemented the upper combustion scheme.

Principle of operation of the bulery furnace

Boilers-furnaces Buleryan

Initially, the buleries were (and there) convection type furnaces. They are equipped with powerful convectors, allowing literally for 20-25 minutes to warm the room large size. Appearing initially in Canada, these ovens got to Russia, which also boasts a harsh climate (indeed for some regions). The craftsmen turned the furnaces into the boilers, having a slightly working on the construction of convectors - now it circulates not air, but the heat carrier. True, boilers boilers cannot boast long burning, as they differ not to the largest combustion chambers. Some of them have a property to burn to 10-12 hours, some are a little longer. But I still do not have to count on 24 hours. But they are distinguished by high efficiency and the ability to maximally give heat into the heating systems.

Brief guillery instructions

If you want to make a hard-fuel burning boiler with your own hands, then the drawings will become a point of shipment for you - pick up the option that will be under force and proceed to action. In this section, we will look at several drawings and give brief assembly instructions.

Independent assembly of a mine boiler

So, before you the easiest drawing of a long burning boiler on shaft-type firewood. If you have experience analysis of drawing schemes, you can easily build this heating unit. By the way, it is assembled not only from the metal, but also from bricks - to ensure the resistance of the unit to high temperatures, you will need chamoten brick. Structurally mining and long burning boiler consists of the following parts:

  • Fuel Bookmark cameras - firewood is loaded here. At the top there is a boot door;
  • The grate grille - separates the loading chamber from the ash bar. It is on the lattice that the focus of the flame is located;
  • A chamber with a winter-tube heat exchanger - a flame transfers heat into the heating system here;
  • Chimney - the combustion products are removed through it.
Drawing of a mine boiler

There are dozens of drawings of mining boilers of long burning, we also chose on this.

Remember that by creating an impressive loading chamber, you will provide a long burning of firewood in your boiler.

We collect pyrolysis boiler

The assembly of the pyrolysis boiler of long burning begins with the choice of a suitable drawing. The thing is that here the variety of schemes is even more. Some drawings repeat successful factory models, and some are handicrafts. The basis is best to take a scheme with a water jacket. In this case, the combustion chambers and afterburning are located within the aggregate itself, washed by water almost from all sides. This scheme ensures maximum heat selection and user security.

Pyrolysis boiler for long burning is equipped with a large combustion chamber, in which firewood is smoldering. Pyrolysis released products are sent up - to the afterburning chamber (in the figure above). The smoke formed and solid particles are sent to the chimney. There are no traditional wood heat exchanger here, but there are schemes where there are heat exchangers and shirts.

Drawing of pyrolysis boiler

One of the most effective pyrolysis boiler schemes, from those available in the manufacture of themselves.

Separate schemes include the creation of a contour of the preparation of hot water - this happens in this. Equipment will be difficult, but more functional. Detailed instructions for assembling pyrolysis boiler you will find in our reviews.

Collect the boobon boiler

Bunch of long burning boiler is the easiest heating unit. He is easier than his pyrolysis fellow, thanks to which it is in certain demand. Bunch can be collected from any suitable capacity - for example, from an old gas cylinder or a suitable barrel. Also for this fit steel sheets, collecting more reliable and durable aggregates.

As the basis, you can take a scheme with a heat exchanger, to the chimney pipe. N. You're better to make a water shirt or coagulate the body of the pipes (in this case, the housing must be quite thick, up to 4-5 mm) - this scheme will improve the selection of thermal energy. For a small house or giving bunching will become the best option, but it must be remembered that the boiler itself must be installed in a non-residential room. The thing is that its extracts is carried out in an open way, and smoke will go indoors.

Constructive boiler for long burning based on the bunch of the bunch consists of the following nodes:

  • The housing is a combustion chamber, it also forms a loading chamber;
  • Clamping piston - it provides air supply and slightly presses firewood;
  • Chimney - assigns combustion products.
Drawing of boiler bunching

Firewood clogs almost all internal volume. For example, if you create a combustion chamber with a volume of 200 liters, then the lamps are enough for 2-3 days of work, and not just 24 hours.

Detailed instructions for assembling bubfoni with drawings you can find in reviews published on our website.

Boiler Buleryan

The basis of a long-burning boiler is an impressive combustion chamber formed by the cunning weave of the curved metal pipes. These pipes were originally convectors of the stoves of the same name, but in our case they will play the role of a powerful water heat exchanger. Heat transmission here is really very good, since the pipes are directly in contact with flame and burning firewood.

To build a buleryan, it is necessary to prepare leaf iron and pipe with a diameter of at least 60 mm. They bend the pipe bend, after which they are welded with each other, forming the basis of the future of the long burning boiler. Next stage - Sealing the combustion chamber, installation of doors and installation of chimney. Special attention is paid to convection pipes - they are welded from below and on top together, forming a large water heat exchanger.

The finished design is installed on a non-combustible base and connects to the chimney-derived chimney. Please note that for correct operation of data of long-burning boilers, chimneys are needed with a height of at least 5 meters. It is also desirable to organize a condensate collection - a lot is formed here.

Drawing of boiler boiler

The boiler collected by such scheme will delight the ease of ignition and the highest heating system as quickly as possible.

Step-by-step instructions for assembling the oven for long burning buleries can be found in our reviews. You will only have to finalize the system of feeding convectors to work with the coolant.

Despite the huge amount of heating devices presented in the market, a popular option is a solid fuel boiler for long burning.

Homemade TT Cable for Long Burning

Homemade TT boiler long burning

This unit can be used as the main source of heating in remote areas where gasification and electrification is not provided. Reliable, efficient and economical, it is an excellent solution for the heating of a country house, a cottage in the city or cottage.

Unlike the usual boiler, where the main heat goes from the flame itself, the TT of a long-burning boiler works at a completely different principle. In this article, we will talk about how to properly make a solid fuel boiler for long burning with your own hands, and the drawings and the installation scheme will help you not make a mistake and do everything technologically correctly!

Principle of operation of a long-burning boiler

In conventional solid fuel units, one bookmark is enough for 6-7 hours of burning. Accordingly, if the next portion of resources is not added to the furnace, the room temperature will immediately begin to decline. This is due to the fact that the main heat in the room circulates on the principle of free gas movement. Heating from the flame, the air rises up and comes out.

The heat resource of a long-burning boiler is enough for about 1-2 days from one firewood. Some models can maintain heat to 7 days.

Due to what is achieving such efficiency and efficiency?

The scheme of the boiler

The scheme of the boiler

From the usual boiler, the TT pot of long burning is distinguished by the presence of two combustion chambers at once. In the first standard, fuel itself burns, and in the second - allocated gases.

A high role in this process plays a timely oxygen supply, which the fan provides.

This principle was implemented relatively recently. In 2000, the Lithuanian company STROPUVA for the first time presented this technology, which inheritance reducing respect and popularity.

Homemade boiler long burning

Homemade boiler long burning

Today it is the cheapest and practical way to warm the country house, where gasification is not provided and there are interruptions with electricity.

Such aggregates work on the principle of the combustion of the upper fuel. Standardly in all furnaces, the furnace is located downstairs, which allows you to take cold air from the floor, heat it and raise up.

The principle of operation of this boiler is something like a pyrolysis. The main heat here is not allocated from the combustion of solid fuels, but from the excreted gases as a result of this process.

The combustion process itself occurs in a closed space. Through the telescopic tube, the released gas enters the second chamber, where its full combustion and mixing with cold air, which sweeps the fan.

TT Cotele Long Burning (Scheme)

TT Cotele Long Burning (Scheme)

This is a continuous process that is happening until the fuel fails. Temperature with such burning is achieved very high - about 1,200 degrees.

As mentioned above, two cameras were implemented in this boiler: the main big and small. The fuel itself is laid into a large chamber. Its volume can reach 500 cubic meters.

The combustion resource can act any solid fuel: sawdust, coals, firewood, pallets.

Permanent air flow performs a built-in fan. The advantage of this method is that solid fuel is consumed extremely slow.

This significantly increases the efficiency of such a heating device. Why are firewood so slowly, compared with a standard oven?

The essence lies in the fact that only the upper layer is roasted, as the air is injected with a fan from above. Moreover, the fan adds air only after the upper layer completely prohibit.

There are many models that work in the same principle today, but, depending on the dimensions, the material of execution, additional options, have different efficiency and efficiency.

Versatility fuel

Versatility fuel

Universal TT boilers work absolutely on any fuel, which will significantly simplify the owners of their operation. A more fiscal option is a wood tt of a long-burning boiler. It works exclusively on firewood and the other version of the fuel cannot be laid in it.

Feature design

Any long-burning boiler is equipped with an impressive size chamber where fuel is laid. The larger the camera is equipped with a boiler, the larger the amount of time will be littered.

Today you can meet two technologies implemented in TT boilers of long-term combustion, which successfully compete with each other. This is the principle of buleryan and the sling method.

Due to the high rapid price and the complexity of the structure, this method is not as popular in Russia. But according to the method of Buleryan, folk craftsmen with great self-dedication design aggregates for the heating of cottages and country houses.

Scheme TT Cotele

Scheme TT Cotele

The boiler boiler is as follows: a metal case, inside which are two cameras. In the lower chamber, fuel combustion occurs, and in the second - burning gas coming through the tube from the first chamber.

The door to load the fuel is in the upper part of the boiler housing, since the entire bottom of the bottom of the resource tab.

In the upper part of the boiler there is a flue nozzle that connects with chimney. A coil camera is embedded in the lower part through which the boiler is cleaned.

It should be mentioned about one nuance. In standard furnaces, the ashnik acts as a role, through which the air required for burning is blown. Here the ash camera is absolutely sealed, as the air enters through the upper air chamber playing the role of the recovery.

The supply of oxygen into the boiler adjusts the damper located at the top of the air chamber. As the firewood is combustion, the fuel gradually settles and the distributor is descended. This ensures uninterrupted oxygen supply.

With a new boot of fuel, it is enough just to pull up, returning to distribute to its original position. On the position of this lever, you can easily determine how much fuels remained in the boiler and when to carry out the next load.

Separately, it should be said about the environmental friendliness of this heating. Because of the complete combustion of fuel and gases, carbon dioxide is practically not emitted into the atmosphere.

The main elements of the TT boiler of long burning

The main elements of the TT boiler of long burning

The main elements of the TT boiler:

  1. Floor chamber. This is the main element of any boiler and the furnace, where the direct burning of fuel occurs.
  2. Gas combustion chamber. Hot gases come here from smoldering firewood.
  3. Solnik - the ashes going here. This node must be systematically clean to support the boiler in a technically good condition.
  4. The chimney is a node through which the combustion products are output.
Boiler device

All these nodes are enclosed in a steel case, which is made of a sheet metal with a thickness of 5-6 mm.

Advantages and disadvantages

Due to large dimensions, the complexity of the design scheme, such an aggregate is rational to use a large cottage for heating. But for a small cottage, this option is not suitable, as they do not justify the cost-effectiveness.

pros

  • high efficiency (about 95%);
  • autonomy of the heating system;
  • economy;
  • reliability and durability;
  • high efficiency;
  • availability of fuel;
  • Environmentally friendly option of home heating;
  • The versatility of fuel (coals, firewood, sawdust, pillars).

Read our stuff about what boilers long burning is better.

Minuses

  • the bulky structures;
  • Under the device it is necessary to equip a special room;
  • complexity of design and installation;
  • The need for constant cleaning.

The boiler of long burning is not necessary to buy in the finished form, because its price is several times higher than ordinary stoves. This design can be made independently if you have at least a small experience in construction and repair.

Exterior of self-made design

Exterior of self-made design

The homemade design, compared with the factory analogue, have a number of advantages:

  • low cost;
  • the ability to make the boiler universal for any type of fuel;
  • The possibility of improving the design and the addition of power.

The only complexity is to give the cylindrical form of the boiler. Without roller machine, this form is very difficult for the metal.

But there is a good solution. You can use empty cylinders for propane or any pipe of a suitable diameter. You should choose pipes, the wall thickness of which is at least 5 mm.

For the village and a small cottage you can add a small brick oven and rejoice in its effectiveness. But for a large cottage this option will be less practical, as it will require a large stock of firewood for the winter. Caring for a conventional oven, compared to a long-burning boiler, is much more complicated, and large temperature differences in the rooms remote from the furnace are not allowed to organize a comfortable microclimate in the house.

If you do not have enough money to create a full-fledged heating system for the house, or the construction of such a system is inappropriate - much more reasonable in this situation will make a solid fuel boiler for long burning with their own hands and not worry about its preservation and aesthetic appearance.

Useful tips on the manufacture of TT boiler

  • If you want to make a TT boiler universal from the position of using raw materials, then use a tube from heat-resistant alloy steel. Alloy steel pipe for boiler

    Alloy steel pipe for boiler

    It is possible to significantly reduce the cost of building an aggregate if you take a seamless steel pipe 20 brand.

  • Before installing the boiler to the place, which is determined by this unit, spend the first extract on the street, equipping the boiler by temporary chimney. So you will be convinced of the reliability of the design and see whether the case collected correctly.
  • If you will use a gas cylinder as the main chamber, consider that such an aggregate will ensure that there is a burning of 10-12 hours due to a small amount of fixed fuel. So a small volume of the propane cylinder will decrease after cutting the lid and the ashtar. To increase the volume and provide greater burning time, you must use two cylinders. Then the volume of the coil chamber is definitely enough for heating a large room, and it will not be necessary to lay firewood every 4-5 hours.
  • So that the door of the ashtar closes tightly without giving air access, it is necessary to seal it well. To do this, around the perimeter door pave asbestos cord. Asbestos cord

    Asbestos cord

    If you will perform an additional door in the boiler, which allows you to "help" the fuel without removing the covers, it is also necessary to tightly seal using an asbestos cord.

To operate a TT boiler, whose scheme we attached below suitable any solid fuel:

  • Stone and brown coal;
  • anthracite;
  • firewood;
  • Wood pellets;
  • briquettes;
  • sawdust;
  • Shale with peat.

There is no special indication in the quality of fuel - anyone will suit. But consider that with a large moisture of fuel, the boiler will not give a large efficiency.

Security measures!

So that such a boiler is indeed an efficient and economical option of heating, served a long service and did not cause burns or accidents in the house, consider the highlights of fire safety.

TT Cotele

TT Cotele

  1. It is necessary to monitor the temperature in the system and prevent its overheating.
  2. You can not install a shut-off valve on the pipeline.
  3. Next to the boiler can not be made easily flammable items.
  4. It is necessary to monitor ventilation indoors.
  5. For the boiler you need to equip a separate room.

At the preparatory work, consider the place where the boiler will be installed.

Ideally, of course, equip a separate boiler room, because the operation of the TT of a long-burning boiler is somewhat different from the familiar brick oven on firewood. And externally, this unit will not please the eye, and serve the decoration of the house.

Given that solid fuel still creates a certain dirt, the TT of a long-burning boiler is better to establish a non-residential room.

But if its power is small (does not exceed 30-35 kW), then you can simply separate (zonate) the main room from the "boiler room" with the help of a brick wall.

Be sure to pride the ventilation system in the room where the operation will occur with this boiler. Oxygen must come on a permanent basis from the street.

Step-by-step instructions for creating a solid fuel boiler for long burning with their own hands

The project of a solid fuel boiler - the task is not easy and new to cope with it will be not easy. Before proceeding with construction, prepare drawings and sketches.

Drawing of homemade solid fuel boiler

Drawing of homemade solid fuel boiler

Prepare also the following tools:

  1. Welding machine.
  2. Metal Tools: Pliers, Grinding Circle.
  3. Electric drill.
  4. Construction level and roulette.
  5. Marker.
  6. Bulgarian.
  7. Gloves and protective screen on the eyes.

Attention! When performing work on the manufacture of a homemade TT of a continuous burning boiler, you should be very careful and have at least basic practice with the welding machine. Use sure to protect when working with welding.

Materials will need:

  1. Empty gas cylinder.
  2. Sheet metal.
  3. Asbestos cord.
  4. Steel pipe with a cross section of 60 mm.
  5. Metal loops and handles.
  6. Metal corner or blade.
  7. Metal hood.
  8. Basalt fiber for the passage of the chimney pipe.

Before the start of the manufacture, we suggest you will get acquainted with the video instruction, how to correctly cut an empty gas cylinder, look carefully and do not neglect the safety measures!

Step 1. Marking of the case and the manufacture of the case

With the help of the marker, perform marking on the propane cylinder according to the drawing size.

We make a small rectangular hole under the doors of the ashtar, through which the boiler cleaning will be carried out.

On the upper part of the cylinder (throughout the perimeter), we carry out a flat line for the slice cut.

With the help of a grinder, cut off the top.

Cutting the top of the cylinder

Cutting the top of the cylinder

Now in the center we carry out the markup under the hole through which the pipe will pass. The hole, respectively, should be larger than the pipe diameter.

Cut the hole in the lid and weld the metal ring, which will be tightly wrapped the pipe inserted into the cylinder.

Weld the ring in a circle

Weld the ring in a circle

Watering with a small ring of sheet metal (4-5 mm) from the external and inner side of the balloon itself, to which the lid will be put on.

Step 2. Pipe Production

We take a metal pipe from 80 to 100 cm long. If you are using a non-propane standard cylinder, and independently boil the housing for the boiler, consider that the pipe height must be 20-25 cm above. After all, the essence of the work is that as the fuel is roasted, the pipe inside the case will fall down.

We weld to the pipe at its lower part metal circle - air distributor.

Cutting the top of the cylinder

Cutting the top of the cylinder

Cut from the sheet metal mounting, which are securely weld along the clarification line, pre-roof asbestos cord.

Weld the handles to the lid

Weld the handles to the lid

Cropped cut-off top so that it is easily shot and put back. Perform the handle metal and for ease of removal, also weld them to the case.

Step 3. Production of a nozzle to chimney

We make markup on the cylinder in the upper part of it under the hole of the nozzle.

We weld the pipe

We weld the pipe

Cut with the help of a grinder and weld the pipe to output combustion products.

Then the steel chimney pipe joins this pipe.

Step 4. Making asolnic

On the previously made markup under the ash chamber, cut the hole with the help of a grinder.

Cut the zolnik

Cut the zolnik

Separately from the sheet metal, we carry out the door, which then you need to fasten to the brackets to the boiler body.

Hole under the door of the ashbar

Hole under the door of the ashbar

For convenience, you can perform a small loop of thick wire or reinforcing rod and fasten as a handle.

Step 5. Cooking the air supply system

Measure the inner diameter of the cylinder case. Now on the sheet metal, draw the circle, the diameter of which will be 5 mm less internal diameter of the cylinder.

With the help of a grinder cut this circle.

So the air supply system looks like

So the air supply system looks like

We take a metal corner and cut it into 6 equal parts. The size of each part is ½ diameter of the metal circle. For these purposes, the impeller with old blades is still well.

Making the air supply system

Making the air supply system

We weld the metal circles in the same direction counterclockwise.

Step 6. Make the heat exchanger

We will make a heat exchanger designed on the principle of water circuit.

Making heat exchanger

Making heat exchanger

The size of this heat exchanger depends on your personal preferences. What it will be more, the greater the number of firewood you can lay on it, which means that your boiler will be distinguished by the greater burning.

From a sheet metal with a thickness of 5-6 mm, cut out sheets according to the scheme and weld them into a reliable housing, inside which our gas cylinder will be located.

In the upper and lower part of the housing, perform nozzles for connecting the feed and reverse line.

In the central part it is necessary to provide a hole through which fuel will be laid. We perform with a marker markup and cut out the grinder.

Step 7. Total assembly and installation of boiler

Fresh the coat of the roller on the furnace.

We note on the heat exchanger housing, the place where access to the ash tank will be made and cut out with the help of a grinder. We also equip this opening door, which should be very tightly closed, blocking oxygen access to the case.

Collect the boiler

Collect the boiler

Insert the cylinder inside the heat exchanger.

With the help of a welding machine, you brew the pot from above, as a result of which we get an absolutely sealed case, inside the round firebox.

The essence of the TT of a long-burning boiler consists in limited air supply from above, the function of which performs the oxygen supply system.

Fuel (firewood, coal, briquettes) should be loaded very tight so that there are as few spaces between the layers. If the firewood is different in size and tightly, it does not work, then between the layers can be filled with a chips, paper. The more denser this solid fuel mixture will be, the longer the firewood will burn.

Booting boiler should be dense

Booting boiler should be dense

How will this boiler be loaded?

  • Give the air supply limiter from the case;
  • We load fuel through a special door. Fuel is pre-splashing to sprinkle with a special fluid for ignition;
  • put back the pipe limiter;
  • Inside the boiler throw a lit match;
  • After you make sure that the fuel gradually begins to smooth, cover the door tightly.

As the firewood is roasted, the pipe inside the cylinder will gradually fall. At its height, you can always find out how much firewood is now inside.

Step 8. Motor of the Boiler

Such a simple boiler you can perform right on the street in the warm season and test it outdoors, equipping by temporary chimney.

Merging boiler

Merging boiler

If the area of ​​the room exceeds 30-40 square meters, then two cylinders can be cooked vertically, zooming, thus laying firewood.

Step 9. Installation of the boiler indoors

Take away very seriously to the fire safety of the boiler.

It is better to highlight a separate room or make a small fence from tenants to eliminate burns. Still, the housing of the boiler is metallic and unlike a stone oven, there is a high probability of getting a burn.

Install in the place where it is possible to find the chimney. You can remove the chimney in two ways: through the roof or through the wall.

Consider that you need direct access to the boiler, so at a distance of 50 cm next to it should not stand.

  • Perform a brick base under the boiler, putting a solid brick in 2 rows. Check the building level of the base.
  • Observe the distance from the walls (regulated by SNiP). From the furnace door to the wall, the distance should be at least 125 cm. The distance between the side parts and the back side of the boiler and the wall should be at least 700 mm.
  • If the walls in the house are made of wood or any other combustible material, it is necessary to protect the leaf metal or basalt space of the boiler adjoining to overlaps. It is possible to use the usual brick as thermal insulation, which should be put on the perimeter, the place of the boiler adjustment to the wall.

At the output of the chimney through the wall or roof, it is also necessary to ensure proper thermal insulation. To do this, basalt fiber is suitable, which should be tightly paved between the chimney and overlap.

  • Install the boiler on the prepared foundation and check the level as far as the device is worth it. Consider that the gas outlet should be on the same level with the chimney pipe. If the line is horizontal, then the thrust may be broken during operation.

Step 10. We connect the boiler to chimney.

Attention! It is necessary to lubricate the joints of the joints of the compounds of all parts of the chimney among themselves.

Connect the chimney pipe to the nozzle TT boiler. The diameter of the chimney should be no less than the pipe TT boiler. If these parameters do not comply, then the gas output throughput will be reduced.

Connect to chimney

Connect to chimney

As you can see, doing everything with your own hands, you can get excellent, everything is not so difficult as it seemed at first glance! If you clearly follow the instructions, then quickly evaluate the high performance and efficiency of a solid fuel boiler for long burning, which at times exceeds its competitors with the Open Flame principle. This will allow to maintain a comfortable microclimate in the house with minimal care.

Solid fuel boiler do it yourself - video instruction

Owners of private houses that have decided to install a solid-fuel boiler of heating, first of all concern 3 parameters - the thermal power of the unit, its price and the duration of burning from 1 download. These parameters are interconnected than the more power and duration of work, the higher the cost of the heat generator. The only way to reduce the cost is to make a length of long burning with your own hands or entrust work to the masters. We present 2 designs of TT-boilers, detailed drawings and the procedure for manufacturing heating.

How the duration of the burning of solid fuel increases

The dream of many homeowners is to put the boiler on solid fuel, to which you do not have to run with firewood every 4-6 hours. Using this, manufacturers and sellers of heating equipment apply the prefix "Duration of burning" to all in a row heat generators, including a pellet, working independently up to 7 days.

TT boilers with top and front fuel boot
Varieties of classic boilers with an enlarged fuel chamber

The duration of the combustion process is made to justify the use of mode with limited air supply. But burn firewood and coal in this way ineffective, and that is why:

  1. Wood and coal boilers reach their efficiency 70-75% during the maximum burning. When draining the efficiency of the unit is reduced to 40-50% (as in conventional burzhuyki).
  2. Glowing firewood is isolated by little thermal energy. Who needs a "long-playing" heat generator, not a heating house fully?
  3. Fresed tree of certain rocks (for example, poplar, IVA) and low-calorie fuel can not be burned normally in the mode of tension.
Super-top burning boiler
Factory boiler with increased pop-up, where firewood burns from top to bottom

In fact, solid fuel boilers of long burning are those that have an increased fuel chamber, only its size affects the duration of the process with other things being equal. The principle is simple: the more in the firewood firewood, the longer they burn and distinguish heat.

Household boilers capable of working with one bookmark 8-12 hours on firewood and up to 24 hours on the corner, there are such species:

  • classic, with forced air supply;
  • existing on the principle of the upper combustion (such as the Baltic "Rods").

These designs of TT-boilers are quite realistic to make at home in the presence of necessary tools and practices in the welding business. Even on the Internet, you can find drawings of mine boilers on solid fuel and sawdust, but such heaters are quite cumbersome and difficult in manufacture, and therefore deserve a separate topic.

Classic continuous burning boiler

In this section, you are offered to your attention a homemade heating unit on firewood and coal, developed and made by our expert Vitaly Dashko. The master gathered several dozen-like thermal generators of different power, constantly improving the design. Brief overview TT-boiler Look at the video:

The reliability and efficiency of boilers is already tested by time on various objects. The specifications of the presented model of the unit are as follows:

  • Power - 22-24 kW;
  • Burning duration (on average) on firewood 10-12 hours, at least 8 hours;
  • The same, on the corner - up to 1 day;
  • KPD - 75-77%;
  • Maximum operating pressure in the heating system - 3 bar, nominal - 1.5 bar;
  • The amount of water in the boiler pot is 50 l;
  • Product weight - 150 kg;
  • size of the loading opening (width x height) 360 x 250 mm;
  • The total volume of the furnace is 112 liters, useful (under the load of fuel) - 83 l;
  • The depth of the furnace is 46 cm, the optimal length is linked - 40 cm.

For reference. The master makes the boilers of long combustion of different power, the line includes aggregates at 16, 24, 36 and 130 kW. The price of a finished product for 24 kW when ordering the master is about 450 y. e. All questions and clarifications associated with the device of a solid fuel boiler and its manufacture can be discussed personally with Vitaly, whose contacts are listed on the page "Our Experts".

Device and overall dimensions of a long-burning filling boiler for manufacture with your own hands are shown in the drawing:

Traditional TT-Boiler Drawing - Front and Side Procedure

The heat generator successfully functions both on firewood and in coal fuel. The useful capacity of the fuel is considered to the lower edge of the loading opening, since the chamber is undesirable to fill the top. The work of the boiler is happening in this order:

  1. After laying and ignition, the solid fuel doors are tightly closed.
  2. The desired temperature of the coolant is displayed on the electronic control unit, it is recommended not lower than 50 ° C. Then the unit is turned on to work by pressing the corresponding button, the fan starts.
  3. When heated to the set temperature, the fan is turned off, air access to the fuel is stopped. The TT-boiler is in standby mode, firewood is very weak and practically do not give heat.
  4. After the temperature drop in the boiler tank, the controller gives the command to start the fan and the combustion process in the furnace is resumed.

The controller changes the performance of the fan at its discretion to achieve maximum combustion efficiency. Burning in this homemade boiler is absent, it is either in a state of waiting, or burns wood and carbon in intensive mode.

The internal device of the unit is shown in the drawings of the boiler in the section:

How the TT-boiler is a long burning

In the heating installation, a classic method of burning solid fuels with a direct transmission of heat walls of a water shirt and a severity that is the bottom of the boiler tank is implemented. This tank is immersed with a winter-tube heat exchanger that selects the heat of flue gases. Air heated in the channel is fed to the furnace from below, through a grate grid. The duration of burning is ensured by:

  1. Large volume of the fuel.
  2. Full overlap of air access in a firebox in standby mode. After turning off the fan, the gravitational flap is triggered, covering the air duct and in such a way that does not give the chimney to inflate coals.

The rear and heat-tube heat exchanger device is shown in the following drawing:

Tools and Materials for Manufacture

On the blanks for the assembly of a solid fuel boiler of long burning, there is usually low carbon steel grades of Art 3, 10, 20. The best option - Article 20, made from it heat generators serve to 15 years. Steel containing more carbon (ST 35, 45) has the property to be embedded from high temperature, and therefore for welding the heat generator is unsuitable.

If you have sufficient experience of welding work and the opportunity to buy a metal is more expensive, then the combustion chamber can be made of heat-resistant steel, doped chromium and molybdenum (for example, 12xm, 12x1mf). How to independently determine the brand of steel with a sufficient approach, told in this article.

List of blanks, of which you will collect a solid fuel boiler with your own hands, is given in the form of a table:

The statement of materials - the size of the boils of the boiler

Council. Billets are best chopped on guillotine scissors somewhere in the workshop. So you will save a mass of time on hand cutting and sweeping from burrs.

Such materials will be required:

  • a corner of an equal 50 x 4 mm for the manufacture of grate;
  • DN50 pipe - heat exchanger and nozzles connecting heating system;
  • pipe DN150 - on chimney nozzle;
  • Pipe Profile 60 x 40 mm for air canal;
  • steel strip 20 x 3 mm;
  • Basalt insulation density of 100 kg / m³ and 2 cm thick;
  • Smooth sheet metal 0.3-0.5 mm with polymer color;
  • Ready handles on the doors;
  • Cord, cardboard asbestos.

From the tools it is worth noting the apparatus of welding, grinder and drill, the electrodes of ANO-21 or MP-3C are used for welding. The rest is a standard set of measuring devices and tools available in each home.

Automation set for wood heat generators
The fan and the control unit of Polish production is suitable for any self-made TT-boiler

As used in the TT-boiler, a set of automation consisting of a control unit, a fan and a temperature sensor - Polish production (do not confuse with Chinese, it looks the same). Marking of the control unit - KG Elektronik SP-05, fan - DP-02.

Assembly of the heating aggregate

First step The manufacture of a long burning boiler is to assemble the casing of the metal of metal with a thickness of 4 mm welding on the patches. It all starts with the bottom of the unit, to which the side walls are grabbed, the cover of the arch and opening of the door, as shown in the photo:

Assembling chamber combustion wood boiler

The bottom sheet is produced in each direction in accordance with the drawing, at the same time it serves as the lower framed of the doors of the ashtar. Inside the chamber on the weld, the shelves are fixed from the corners, where the grate grille will be rejected. The assembled fuel is thoroughly rocked on all the joints and is checked for tightness.

Side-made TT-Boiler Top Side

Second phase - Installation of a water shirt made of metal 3 mm. Its thickness in the side walls is 2 cm, so the segment of the steel strip should be segged to the body of the fifuel, by releasing them by 20 mm. These grabbed steel sheets of the sheath.

How to make a water shirt boiler

Attention! The water shirt begins at the level of the grille and does not wash the ash chamber.

In the middle of checker, so-called clips are set. This is a steel circle, passed through the holes in the wall of the boiler tank and welded to the oscillate. The second end of the clip is boiled around the hole, as shown in the photo:

How to fix the waters of the water shirt TT-boiler
In the photo on the right, it can be seen where the bottom of the water shirt is located, on the left - a boiler

A few words about how to make additional clips on the edges of the water shirt of the self-made solid fuel boiler. You need to take a 20 mm strip and insert it from the end between the walls to a depth of 50-100 mm, and then welcome on both sides.

Third stage - Installation of heat pipes in the upper part of the boiler tank. To do this, in the rear and front wall, the holes cut through the drawings where the pipes are inserted. Their ends are hermetically copier, as well as all the junctions of the water shirt.

How to make a fire-cutting heat exchanger of the boiler
Heat exchanger iron pipes diverge to fan from chimney nozzle

Fourth stage - Production of the door and grate grid. The doors from the inside weld the strip in 2 rows, and the asbestos cord is investing between them, it will be a seal of the gunner. Colonsets are made from the corners No. 5, welded with an outer angle down. So they serve as air scatteers served by a fan in the ash bar.

Homemade doors and coopers of boiler installation

At the fifth stage In the walls of the boiler tank, fittings are embedded to connect the feed and return pipeline, the chimney can be installed and the air channel from the pipe 60 x 40 mm with the fastening flange of the fan. The air duct enters the ash chamber in the middle of the rear wall, immediately under a water jacket.

Channel forced air supply to the heating unit chamber

Stage Sixth - welding of door loops and mortgage parts 2 cm wide for fastening the decorative sheatting of a long-burning boiler.

How to make staples to cover a wood heat generator

Stage seventh , last. The boiler tank is placed on the side and above the basalt insulation, the latter is fixed with the cord. After it remains to fasten the sheets of painted metal with self-draws to mortgage parts and install doors.

How to insulate the combustion chamber TT-boiler
The dense basalt fiber warms the body and calmly maintains the heat. Glazed not worth applying

At the end, the fan is attached at the response flange of the duct, and the control unit is installed on the boiler on top. The temperature sensor must be attached to the basalt insulation from the back of the rear wall of the unit. In addition, a number of useful additions can be made in the design of the home-made boiler for long burning, according to your desire:

  • Built in a boiler tank of water circuit of water heating at the DHW;
  • to provide a submersible sleeve for setting the thermometer - in case of turning off the electricity, when the controller display goes out;
  • the same - for the installation of a security group;
  • Install an electric tan, warming the coolant after burning firewood.

A few words about how to make the circulation of hot water in a solid fuel boiler for the purpose of it for heating on economic needs. You need to take 10 m copper tubes with a diameter of 8-12 mm and to bring a coil from it in the form of a spiral. The latter is wound inside the boiler tank around the heat pipes, and the ends are outward from the rear side of the unit. We get a dual-circuit boiler for long burning.

Note. The practice of exploitation of heat generators has shown that the installation of the electric heater is necessary for the homeowners who wishes to damn the house at the night rate. In other cases, the length of the burning is enough, so as not to run into the boiler room among the nights in order to throw firelines.

The legs of the unit can be attached at any stage by choosing the right segments of the metal. Details and secrets of assembling TT-boiler, see the author's video master - the creator of the heating unit:

Copper with upper burning fuel

In the post-Soviet space, these heat generators are known in two varieties:

  1. Baltic aggregates of the company "Stropuva" and their derivatives from other manufacturers.
  2. Woody stoves like "bunch".

It is not known which of the heaters earlier, but the bunch of the bunch has won wide popularity as a heater for cottages, garages and other buildings with low product aesthetics requirements. What can not be said about the boilers of the upper burning, although many of them for some reason consider the only possible version of solid fuel heat generators of prolonged incineration. In fact, their only trump card is all the same - a large-sized fifth.

The principle of action of such boilers is to burn the fuel attached by the cargo in the direction from top to bottom. Moreover, the air is supplied to the burning zone is also on top, along the telescopic tube connected to the load. The working circuit of the unit is shown in Figure:

STROPUVA heat generator device - scheme
Original boiler scheme taken from Stropuva.ru

In the process of operation of STROPUVA boilers, many flaws were manifested, as evidenced by the reviews of the owners on the forums:

  1. It is impossible to throw in the firebox of the lane, until the previous bookmark burns. Physically, it is possible, but then the principle of the upper burning will break, the flame will cover all layers of fuel.
  2. When working on fresh sawdust and other small garbage, fuel residues "hang" on the walls.
  3. The effectiveness of the TT-boiler is not too high, since it does not have a heat exchanger. Due to the air heating chamber and a large fuel cell for the heat exchanger, there is no place left.

There is no more critical flaws from the heat generator, and something in the homemade version can be corrected in its understanding. For example, put the bottom and grate, organizing an ash chamber. You can get rid of a lack of a fitting device, if you put an additional door between the loading and ash opening. This idea of ​​upgrading the upper burning boiler belongs to another expert - Vladimir Sukhorukov, what he tells about in his video:

Preparation of materials

The round case creates some inconvenience in the manufacture, but you can't do it square, the fuel will "hang" in the corners. There is a problem and with the assembly of a telescopic pipe with a cargo, so that this part is better to take from the bunching furnace. Drawing of a long-burning boiler, comparable in size with a classic version, looks like this:

Drawing of the upper burning boiler in the context

Before making a boiler, we select materials according to the drawing:

  • pipe DN 400 with a wall of 5 mm - on the fuel cell;
  • The same, DN 50 - on air supply and water nozzles;
  • The same, DN 100 - for chimney;
  • Billet from a leaf of a thickness of 10 mm round shape with a diameter of 38 cm;
  • strip 40 x 4 mm - for air distributors;
  • Armature with a diameter of 16-20 mm of a periodic profile - to grate;
  • Basalt wool 3 cm thick and 100 kg / m³ density;
  • Polymer metal coated metal.

The choice of water shirt material depends on the method of its installation, because the domestic master is unlikely to be in stock rollers, capable of making metal with a thickness of 3 mm. Options are (are shown below in the diagram):

  1. Scheme number 1. Take a thin-walled pipe of a larger diameter, although it is not easy to find such, and the usual drowned the boiler.
  2. Scheme number 2. Two metal sheet bend in 2 places at an angle of 60 °, and then cook two halves together. It will take a press listogib.
  3. Scheme number 2 in another execution. Cook a shirt of 6 sheets - segments on clips.
  4. Scheme number 3. Cook a rectangular box, which will increase the volume of the boiler tank.
Round Boiler Water Shirt Production Schemes
Scheme number 2 can be implemented in two ways - cook from 2 bent halves or 6 flat sheets

Also need a sheet metal 3 mm on the framing of the door, the bottom with the lid and the air damper.

Production of heat generator

The production of work begins with cutting blanks and openings in the pipe wall in size in the drawing. Doors are made from the cut parts, sheds and purchased handles are fitted. From the reinforcement, the grate grille shown in the photo:

How to make a grate of the armature grid

In general, the algorithm for assembling the boiler of the upper burning looks like this:

  1. In a round billet for cargo cutting hole, insert a pipe into it and ribbon.
  2. To the lower part of the cargo, welcome 6 curved bands, which will serve air distributors.
  3. Attach the bottom of the bottom, set inside the grate.
  4. Cutting a hole in the center of the cover for the air pipe, to adapt it to the fuel. Before that, you need to put the pipe with the cargo in place.
  5. Siggle the flue of the chimney.
  6. Mount the water shirt on the selected scheme, hermetically rolled all the joints.
  7. Conduct the cutting of the pipes for the coolant.
  8. Perform insulation and boiler trim, install doors.
  9. Put a damper on the top of the air pipe.

For air distribution, it is enough for six lanes-distributors

Installing automation and superimposed on the boiler for a long-term upper combustion is difficult, because the fan will not stick to the moving pipe. It is necessary to make a flexible sleeve, and for the temperature sensor to provide a submersible sleeve. It is impossible to invest it under the insulation, because the burning zone in this form of heaters is constantly shifted down.

Testing the boiler is better, of course, on the street

Conclusion

Both designs of solid fuel boilers of long burning made by their own hands have the right to life. But to manufacture a reliable heating unit is not easy - the joints of the metal need to trip well and tightly. Without experience and qualifications, the welder can not do. Hence the output: If you see that you will not overcome an independent assembly or you do not have time for this, refer to the masters. So you will save up to 50% of the funds compared with the purchase of a factory TT-boiler.

Sometimes it is advisable to make a solid-fuel long burning boiler with your own hands: drawings and schemes are free access. The ability to handle the tool and skillful hands have a good service when building your own home or cottage. There there is always the need to build any design yourself. After all, this significantly heshes any idea. No exception and heating units. In the old days, people hired a burn for masonry brick stoves. Today, boilers on solid fuel for long burning are most popular.

A solid fuel boiler for long burning is quite realistic to do it yourself.

Principle of operation of solid fuel boilers and their device

Solid organic fuel is the most ancient source of energy for humanity. It is impossible to refuse it completely, even in the modern world. Moreover, in addition to firewood and stone coal, many other types of combustible solids appeared today:

  • peat briquettes - dried and compressed peat highlights a lot of heat during combustion;
  • Woodworking waste briquettes - compressed sawdust, chips and trees bark;
  • Birch coal - the same as for the manga;
  • recycled garbage from landfills;
  • Fuel heating granules - fine fuel obtained by pressing sawdust. Can be fed automatically;
  • Ordinary dry sawdust.
TverDoTOPLIVNYJ-KOTELNOGO-GORENIYA-FOTO-Video-CHERTEZHI-KAK-SDELAT-SVOIMI-RUKAMI-2
Various options for raw materials for use in solid fuel boilers.

It is clear that all this fuel is obtained by processing various waste, which solves the problem of recycling in enterprises and goes in line with the Green Economy.

On a note! The most affordable fuel, of those listed above are wood sawdust. If you intend to use them for heating - make sure that they are with a humidity of less than 20%. The greatest indicators of this parameter will not allow the pyrolysis gas to be produced, since most of the heating energy will go on drying fuel.

As a result of human activity, a tremendous amount of waste is formed, which can be transformed into high-energy fuel, which led to the emergence of long-burning heating boilers in the market. Unlike conventional furnaces, these aggregates do not work on the combustion of the fuel itself, but on its splitting as a result of heating. In the working chamber of such boilers, gaseous products of solid fuel decay are burned. Such a scheme of work is several times more efficient than the usual combustion of organic fuel. Pyrolysis gas gives a large amount of energy.

Principle of operation of a solid fuel boiler for long burning.

The device of such a gas-generated installation is not very complex. You can even build a solid-fuel long burning boiler. The drawing of the simplest option looks like this:

  • The closed cylindrical tank, which has a hatch for a fuel laying, pondered and a hole for the installation of the chimney;
  • Inside the tank is a distributor of air, which creates a pyrolysis gas turbine. It is attached to the movable telescopic tube. All this design, similar to the piston, presses on fuel from above. The combustion of gas occurs over the piston, and the fuel is smoldering under it;
  • The heat exchanger is built into the upper chamber, where the maximum temperature is achieved.

Slowing solid fuel occurs in the bottom chamber. It is achieved by adjusting the air supply in thought. The gas released intensively burns in the upper chamber and heats the coolant.

Scheme of a private house heating system using a solid fuel boiler.

On a note! You should not use the simplest design for the manufacture of the boiler, which will heat the residential building on an ongoing basis. For this you need, or purchase a finished product, or make a more complex and reliable option.

The boilers on solid fuel for long-burning can be indispensable in private homes, in economic structures, garages and greenhouses. Especially they will be beneficial where there is a large wood processing production, as waste at such enterprises give almost free. These units are needed and locally, where there are regular gas supply interruptions. These installations have many advantages, but there is one important disadvantage - a very high cost. That is why today is relevant manufacturing with its own hands of hard-fuel long burning boilers. Drawings for this can be used by varying degrees of complexity. It depends on the level of skill.

How to make it yourself a hard-fuel length boiler: drawings and design schemes

Before starting the manufacture of the boiler, it is necessary to decide on its design. Its selection depends on the appointment of the aggregate. If it is intended for heating a small household room, a garage or a country house, then it is not necessary to do in it a water circuit. The heating of this room will occur directly from the surface of the boiler, by convection of air masses indoors, as from the furnace. For greater efficiency, you can arrange forced by air by air with a fan. In the presence of a liquid heating system in the room, it is necessary to provide a device in the catering boiler in the form of a coil from a pipe or other similar design.

Connection diagram of a solid fuel boiler to the heating system.

The choice of option depends on the type of solid fuel to be used. For heating, ordinary firewood requires an increased amount of firebox, and for the use of small fuel granules, you can arrange a special container from which the granular fuel is supplied to the boiler automatically. For the manufacture of a boiler of solid fuel long burning with their own hands, the drawing can be taken and universal. It is suitable for any kind of solid fuel used.

Drawing of a solid fuel boiler for a long-term combustion of 25/30/40 kW.

We will tell you step by step, how and from which details you can make the heating boiler on solid fuel for long burning along the proposed scheme:

  • Prepare a place where the future unit will be installed. The base on which it will stand should be smooth, durable, hard and refractory. Best for this is a concrete foundation or thick cast iron or steel plate. Walls need to be chopped by refractory material, if they are wooden;
  • We collect all the necessary material and tools: of which we need a device for electric arc welding, Bulgarian and roulette. Materials: sheet 4-mm steel; 300 - mm steel pipe with walls 3 mm, as well as other pipes 60 and 100 mm diameter;

The structure and principle of operation of a solid fuel boiler.
  • In order to make a boiler on a solid fuel for long burning, you need from a large 300 mm pipe cut a piece of 1 m long. You can and slightly less if there is a need for this;
  • From the steel sheet, we cut the bottom on the diameter of the pipe and weld it, supplying it with legs from a channel up to 10 cm long;
  • Air distributor perform in the form of a circle of steel sheet with a diameter of 20 mm smaller than a pipe. In the lower part of the circle, the impeller is welded from a corner with the size of the shelf 50 mm. To do this, you can use a smoothlier of a similar size;
  • From above in the middle of the distributor welding 60 - mm pipe, which should be above the boiler. In the middle of the disk of the distributor, cut the hole on the pipe, so that there is a cross-cutting tunnel. It is needed for air supply. In the upper part of the pipe, the flap is cut, which will allow adjusting the air supply;

  • In the lowest side of the boiler, we produce a small door, equipped with a valve and loops, leading to the ash bar for the convenience of removing ash. From above in the boiler cut the hole for the chimney and weld to this place 100 - mm pipe. Initially, it goes under a slight angle of lump and up to 40 cm, and then strictly vertically up. The flow of the chimney through the overlap of the room should be protected by fire safety regulations;
  • We complete the construction of the heating boiler on solid fuel for long burning by the manufacture of the upper cover. In its center there must be a hole for the pipe of the air flow dispenser. Aditting to the walls of the boiler should be very dense, excluding air entering.

On a note! To ignite, made with your own hands, a solid-fuel long burning boiler, the drawing of which was presented above, it is necessary to: remove the cover and raise the regulator, fill the boiler to the fire and hide it with a fuel liquid, put everything in place and throw a burning beam into the tube of the regulator. When fuel turns around, reduce the flow of air to a minimum so that it starts only to smooth. After that, pyrolysis gas and the boiler will start fire.

Reviews about the homemade solid fuel boiler for long burning

Alexander Nikolaev, Syktyvkar

"I work on the sawmill. Previously, I got home the knots and cutting by the carts. I learned about the boiler solid fuel long burning, the reviews read and decided to do. Happened. Now the firewood leaves three times less, and the heat is as much. "

Nikolai Platonov, Surgut

"I saw a miracle boiler in the garage. We repaired the car with him in the morning. He, as a firewood put in him, so more until the evening and did not touch. I could not understand anything while he did not explain to me the whole scheme. Here, too, I caught fire the idea of ​​myself in the garage to put. A friend said, give drawings. "

How the duration of the burning of solid fuel increases

The dream of many homeowners is to put the boiler on solid fuel, to which you do not have to run with firewood every 4-6 hours. Using this, manufacturers and sellers of heating equipment apply the prefix "Duration of burning" to all in a row heat generators, including a pellet, working independently up to 7 days.

TT boilers with top and front fuel bootVarieties of classic boilers with an enlarged fuel chamber

The duration of the combustion process is made to justify the use of mode with limited air supply. But burn firewood and coal in this way ineffective, and that is why:

  1. Wood and coal boilers reach their efficiency 70-75% during the maximum burning. When draining the efficiency of the unit is reduced to 40-50% (as in conventional burzhuyki).
  2. Glowing firewood is isolated by little thermal energy. Who needs a "long-playing" heat generator, not a heating house fully?
  3. Fresed tree of certain rocks (for example, poplar, IVA) and low-calorie fuel can not be burned normally in the mode of tension.

Super-top burning boilerFactory boiler with increased pop-up, where firewood burns from top to bottom

In fact, solid fuel boilers of long burning are those that have an increased fuel chamber, only its size affects the duration of the process with other things being equal. The principle is simple: the more in the firewood firewood, the longer they burn and distinguish heat.

Household boilers capable of working with one bookmark 8-12 hours on firewood and up to 24 hours on the corner, there are such species:

  • classic, with forced air supply;
  • existing on the principle of the upper combustion (such as the Baltic "Rods").

These designs of TT-boilers are quite realistic to make at home in the presence of necessary tools and practices in the welding business. Even on the Internet, you can find drawings of mine boilers on solid fuel and sawdust, but such heaters are quite cumbersome and difficult in manufacture, and therefore deserve a separate topic.

How the aggregate works

Conventional solid fuel boilers are able to work on one bookmark about 6-7 hours. If after this time in the furnace is not to throw another portion of fuel, it will lead to a decrease in temperature in the house. The reason lies in the circulation of the main heat indoors on the principle of free air movement: after heating, it rises up and goes into the street. The heat resource of one laying of firewood of a long-burning device is designed for 24-48 hours. In some models, burning is supported for almost a week.

The secret here is as follows: Unlike traditional boilers, the diagram of a long-burning boiler includes not one, but two combustion chambers. The first of them is intended for burning fuel, the second - for the gases received from the first chamber. The quality of the process largely depends on the timely air supply, for which there is a fan in the design. Such an approach is innovative: it was first introduced by the Lithuanian company STROPUVA in 2000, after which the drawings of solid fuel boilers of long burning were adopted by leading manufacturers of boiler equipment.

Solid fuel boiler with his own hands drawings

To date, the aggregates working on this principle are the most inexpensive and practical option for heating houses in areas devoid of gasification. The essence of the devices of this type is the burning of the upper fuel. Typically, the location of the furnace is the lower part: as a result, the cold air after heating has the ability to rise up. Long burning boilers are very similar to pyrolysis: the release of the main portion of heat is not due to the combustion of solid briquettes, but from the gas distinguished.

For combustion inside the design there is a special closed space. The chambers are interconnected by a telescopic tube, according to which the gas separated from the first branch comes into second. The process of its survival is accompanied by mixing with cold air, an injected fan. This procedure stems without pauses, until the fuel is complete. It is characterized by a rather high temperature regime - up to +1200 degrees.

The solid fuel combustion chamber has more extensive dimensions: its volume sometimes reaches 500 dm3. It can load coal, sawdust, firewood, pallets. Stable air injection is provided by a built-in fan. The combustion process is characterized by a very slow fuel consumption rate. As a result, the efficiency of boiler equipment increases sharply.

The reason for slow burning lies in the injection of the air, as a result of which only the upper part of the fuel laying is roasted. An increase in air supply takes place only after the top layer is complete. There are a number of heating devices on sale, the essence of which is the same drawing of a long burning boiler on firewood. Different degrees of their economy and efficiency are explained by differences in the size, manufacturing materials and the presence of additional functions. To work universal TT boilers, you can use any fuel, which greatly simplifies their maintenance. The most cost-effective models are the wood tt boilers.

Construction Features and Device

The camera for laying fuel of any long burning boiler is distinguished by impressive sizes. This parameter directly affects the flourishing time of the fuel laying. Currently, there are two successfully competing technologies implemented in TT boilers: it is about the devices of the buleryan and a sling. Dorganiza and the complexity of manufacturing a drawing of a long-burning boiler makes certain obstacles to the dissemination of the last of them in our country. Unlike him, the buleryan method is widely used by folk craftsmen for an independent organization of the heating of country houses.

The drawing of a boiler's long burning boiler on solid fuel consists of the following nodes:

  1. Metal case closing internal chambers.
  2. Lower chamber for burning fuel.
  3. Top chamber for burning gas.
  4. Doors to bookmark firewood. It is located in the upper part of the design due to the large size of the lower compartment for booking the resource.
  5. Smoke nozzle. It is in the top of the boiler and is connected to chimney.
  6. Solo camera. Located at the bottom of the boiler and is intended for its cleaning.

homemade long-burning boilers

There is also another curious detail. As you know, in conventional furnaces, the function pondered by a ash-like: it is through it that the air required for burning. In the case of a buleryan, the ash compartment is made completely sealed: the air supply channel here is the upper air chamber. To adjust the oxygen supply at the top of this chamber there is a damper. In the course of the combustion of firewood in the furnace gradually settle, which leads to lowering the distributor. This ensures a continuous supply of fresh air.

To implement a new load, the distributor can easily be returned to the initial position by pulling it up. The position of this lever serves as a peculiar level of the level of the remaining fuel: in this way, you can determine how much loading the following portion of firewood. Boilers of the buleryan features high ecology, which is explained by a complete blow of fuel and gas: carbon dioxide in the atmosphere practically does not fall. See also: "How to make a boiler on firewood with your own hands - step-by-step instruction."

The device of a solid fuel boiler for long burning as follows:

  • Fire. The main structural element of any boiler or oven. It is intended for burning fuel in it.
  • Department for download gas. Here the gases arrived from the furnace.
  • Solnik. Coupling to assemble ash. It needs regular cleaning.
  • Chimney. Channel for a lead from the branch of the combustion products.

Strong and weak sides

Large dimensions and difficulty performing the drawing of a solid fuel boiler for long burning makes it favorable to use such devices only in large cottages. As for small cottages, it is recommended to choose more economical options for them.

The main advantages of TT boilers of long burning are:

  • High efficiency (about 95%)
  • Autonomy of heating.
  • Efficiency.
  • Reliability and durability.
  • High efficiency.
  • Availability of fuel.
  • Ecology.
  • Wide selection of fuel (coal, firewood, sawdust, pallets).

Long burning boiler drawings on solid fuel

There are also disadvantages:

  • Large dimensions.
  • The need for equipment of a separate boiler room.
  • A complex device of a long burning boiler on firewood.
  • Need in constantly maintenance.

The boilers of this type have a fairly decent cost, but such structures can be manufactured independently.

Advantages of homemade units:

  1. Cheapness.
  2. Universalism in terms of fuel used.
  3. The possibility of subsequent improvements in order to increase the efficiency and addition of power.

The most difficult thing is to make a cylindrical design: for this you need to use a rolling machine. If it is not, there is an option with old propane cylinders. Any pipe of the appropriate section will also be consolidated: the thickness of the metal walls should be at least 5 mm. In the villages were accustomed to be satisfied with small brick furnaces, demonstrating good effectiveness when heating single-storey houses and cottages. If you need to give a vast cottage, then in this case you will need a large fuel reserve. In addition, not to avoid large temperature drops as it removes from the furnace, and it is much more complicated to care for it than for a solid fuel boiler.

Recommendations for the manufacture of homemade boiler

Getting Started by the manufacture of a long burning boiler with their own hands, it is necessary to arm the following tips:

  • In order to use any fuel in the process of operation of the appliance, it is better to make firecase from heat-resistant alloy steel. Some of the work budget helps the use of seamless steel pipe brand 20.
  • Before you make a homemade unit into a boiler house prepared for it, it is recommended to test it on the street, equipping by temporary chimney. This will give the opportunity to check the reliability of the heater and make sure that the body assembly is correct.
  • The main chamber made from the gas cylinder is able to provide a duration for 10-12 hours, because Firewood in it is a bit. Initially, the small inner space of the propane cylinder decreases after removal of the lid and the ash bar. To increase the parameters of the boiler, it can be made of two cylinders. This will obtain a fairly large flue chamber for heating extensive premises and increase the time between the wood bookmarks.
  • The zolnik door must be sealed to close, which will not give the outer air to seep inside the chamber. This is achieved by styling around the perimeter of the doors of asbestos cord. If the boiler has an additional door to make the fuel without removing the lid, it is also sealed in a similar way.

Drawing of a long burning boiler with their own hands

Standard solid fuel uses firewood, anthracite, sawdust, briquettes, peat, stone and brown coal. Special complaints about fuel quality are usually not presented. However, it is desirable that the fuel material is as dry as possible, which will give a high efficiency warranty.

Advantages and disadvantages

Due to large dimensions, the complexity of the design scheme, such an aggregate is rational to use a large cottage for heating. But for a small cottage, this option is not suitable, as they do not justify the cost-effectiveness.

pros

  • high efficiency (about 95%);
  • autonomy of the heating system;
  • economy;
  • reliability and durability;
  • high efficiency;
  • availability of fuel;
  • Environmentally friendly option of home heating;
  • The versatility of fuel (coals, firewood, sawdust, pillars).

Minuses

  • the bulky structures;
  • Under the device it is necessary to equip a special room;
  • complexity of design and installation;
  • The need for constant cleaning.

The boiler of long burning is not necessary to buy in the finished form, because its price is several times higher than ordinary stoves. This design can be made independently if you have at least a small experience in construction and repair.

Exterior of self-made design

Exterior of self-made design

The homemade design, compared with the factory analogue, have a number of advantages:

  • low cost;
  • the ability to make the boiler universal for any type of fuel;
  • The possibility of improving the design and the addition of power.

The only complexity is to give the cylindrical form of the boiler. Without roller machine, this form is very difficult for the metal.

But there is a good solution. You can use empty cylinders for propane or any pipe of a suitable diameter. You should choose pipes, the wall thickness of which is at least 5 mm.

For the village and a small cottage you can add a small brick oven and rejoice in its effectiveness. But for a large cottage this option will be less practical, as it will require a large stock of firewood for the winter. Caring for a conventional oven, compared to a long-burning boiler, is much more complicated, and large temperature differences in the rooms remote from the furnace are not allowed to organize a comfortable microclimate in the house.

If you do not have enough money to create a full-fledged heating system for the house, or the construction of such a system is inappropriate - much more reasonable in this situation will make a solid fuel boiler for long burning with their own hands and not worry about its preservation and aesthetic appearance.

All questions and clarifications associated with the device of a solid fuel boiler and its manufacture can be discussed personally with Vitaly, whose contacts are listed on the page "Our Experts".

Device and overall dimensions of a long-burning filling boiler for manufacture with your own hands are shown in the drawing:

Traditional TT-Boiler Drawing - Front and Side Procedure

The heat generator successfully functions both on firewood and in coal fuel. The useful capacity of the fuel is considered to the lower edge of the loading opening, since the chamber is undesirable to fill the top. The work of the boiler is happening in this order:

  1. After laying and ignition, the solid fuel doors are tightly closed.
  2. The desired temperature of the coolant is displayed on the electronic control unit, it is recommended not lower than 50 ° C. Then the unit is turned on to work by pressing the corresponding button, the fan starts.
  3. When heated to the set temperature, the fan is turned off, air access to the fuel is stopped. The TT-boiler is in standby mode, firewood is very weak and practically do not give heat.
  4. After the temperature drop in the boiler tank, the controller gives the command to start the fan and the combustion process in the furnace is resumed.

The controller changes the performance of the fan at its discretion to achieve maximum combustion efficiency. Burning in this homemade boiler is absent, it is either in a state of waiting, or burns wood and carbon in intensive mode.

The internal device of the unit is shown in the drawings of the boiler in the section:

How the TT-boiler is a long burning

In the heating installation, a classic method of burning solid fuels with a direct transmission of heat walls of a water shirt and a severity that is the bottom of the boiler tank is implemented. This tank is immersed with a winter-tube heat exchanger that selects the heat of flue gases. Air heated in the channel is fed to the furnace from below, through a grate grid. The duration of burning is ensured by:

  1. Large volume of the fuel.
  2. Full overlap of air access in a firebox in standby mode. After turning off the fan, the gravitational flap is triggered, covering the air duct and in such a way that does not give the chimney to inflate coals.

The rear and heat-tube heat exchanger device is shown in the following drawing:

Tools and Materials for Manufacture

On the blanks for the assembly of a solid fuel boiler of long burning, there is usually low carbon steel grades of Art 3, 10, 20. The best option - Article 20, made from it heat generators serve to 15 years. Steel containing more carbon (ST 35, 45) has the property to be embedded from high temperature, and therefore for welding the heat generator is unsuitable.

If you have sufficient experience of welding work and the opportunity to buy a metal is more expensive, then the combustion chamber can be made of heat-resistant steel, doped chromium and molybdenum (for example, 12xm, 12x1mf). How to independently determine the brand of steel with a sufficient approach, told in this article.

List of blanks, of which you will collect a solid fuel boiler with your own hands, is given in the form of a table:

The statement of materials - the size of the boils of the boiler

Council. Billets are best chopped on guillotine scissors somewhere in the workshop. So you will save a mass of time on hand cutting and sweeping from burrs.

Such materials will be required:

  • a corner of an equal 50 x 4 mm for the manufacture of grate;
  • DN50 pipe - heat exchanger and nozzles connecting heating system;
  • pipe DN150 - on chimney nozzle;
  • Pipe Profile 60 x 40 mm for air canal;
  • steel strip 20 x 3 mm;
  • Basalt insulation density of 100 kg / m³ and 2 cm thick;
  • Smooth sheet metal 0.3-0.5 mm with polymer color;
  • Ready handles on the doors;
  • Cord, cardboard asbestos.

From the tools it is worth noting the apparatus of welding, grinder and drill, the electrodes of ANO-21 or MP-3C are used for welding. The rest is a standard set of measuring devices and tools available in each home.

Automation set for wood heat generatorsThe fan and the control unit of Polish production is suitable for any self-made TT-boiler

As used in the TT-boiler, a set of automation consisting of a control unit, a fan and a temperature sensor - Polish production (do not confuse with Chinese, it looks the same). Marking of the control unit - KG Elektronik SP-05, fan - DP-02.

Assembly of the heating aggregate

First step The manufacture of a long burning boiler is to assemble the casing of the metal of metal with a thickness of 4 mm welding on the patches. It all starts with the bottom of the unit, to which the side walls are grabbed, the cover of the arch and opening of the door, as shown in the photo:

Assembling chamber combustion wood boiler

The bottom sheet is produced in each direction in accordance with the drawing, at the same time it serves as the lower framed of the doors of the ashtar. Inside the chamber on the weld, the shelves are fixed from the corners, where the grate grille will be rejected. The assembled fuel is thoroughly rocked on all the joints and is checked for tightness.

Side-made TT-Boiler Top Side

Second phase - Installation of a water shirt made of metal 3 mm. Its thickness in the side walls is 2 cm, so the segment of the steel strip should be segged to the body of the fifuel, by releasing them by 20 mm. These grabbed steel sheets of the sheath.

How to make a water shirt boiler

Attention! The water shirt begins at the level of the grille and does not wash the ash chamber.

In the middle of checker, so-called clips are set. This is a steel circle, passed through the holes in the wall of the boiler tank and welded to the oscillate. The second end of the clip is boiled around the hole, as shown in the photo:

How to fix the waters of the water shirt TT-boilerIn the photo on the right, it can be seen where the bottom of the water shirt is located, on the left - a boiler

A few words about how to make additional clips on the edges of the water shirt of the self-made solid fuel boiler. You need to take a 20 mm strip and insert it from the end between the walls to a depth of 50-100 mm, and then welcome on both sides.

Third stage - Installation of heat pipes in the upper part of the boiler tank. To do this, in the rear and front wall, the holes cut through the drawings where the pipes are inserted. Their ends are hermetically copier, as well as all the junctions of the water shirt.

How to make a fire-cutting heat exchanger of the boilerHeat exchanger iron pipes diverge to fan from chimney nozzle

Fourth stage - Production of the door and grate grid. The doors from the inside weld the strip in 2 rows, and the asbestos cord is investing between them, it will be a seal of the gunner. Colonsets are made from the corners No. 5, welded with an outer angle down. So they serve as air scatteers served by a fan in the ash bar.

Homemade doors and coopers of boiler installation

At the fifth stage In the walls of the boiler tank, fittings are embedded to connect the feed and return pipeline, the chimney can be installed and the air channel from the pipe 60 x 40 mm with the fastening flange of the fan. The air duct enters the ash chamber in the middle of the rear wall, immediately under a water jacket.

Channel forced air supply to the heating unit chamber

Stage Sixth - welding of door loops and mortgage parts 2 cm wide for fastening the decorative sheatting of a long-burning boiler.

How to make staples to cover a wood heat generator

Stage seventh , last. The boiler tank is placed on the side and above the basalt insulation, the latter is fixed with the cord. After it remains to fasten the sheets of painted metal with self-draws to mortgage parts and install doors.

How to insulate the combustion chamber TT-boilerThe dense basalt fiber warms the body and calmly maintains the heat. Glazed not worth applying

At the end, the fan is attached at the response flange of the duct, and the control unit is installed on the boiler on top. The temperature sensor must be attached to the basalt insulation from the back of the rear wall of the unit. In addition, a number of useful additions can be made in the design of the home-made boiler for long burning, according to your desire:

  • Built in a boiler tank of water circuit of water heating at the DHW;
  • to provide a submersible sleeve for setting the thermometer - in case of turning off the electricity, when the controller display goes out;
  • the same - for the installation of a security group;
  • Install an electric tan, warming the coolant after burning firewood.

A few words about how to make the circulation of hot water in a solid fuel boiler for the purpose of it for heating on economic needs. You need to take 10 m copper tubes with a diameter of 8-12 mm and to bring a coil from it in the form of a spiral. The latter is wound inside the boiler tank around the heat pipes, and the ends are outward from the rear side of the unit. We get a dual-circuit boiler for long burning.

Note. The practice of exploitation of heat generators has shown that the installation of the electric heater is necessary for the homeowners who wishes to damn the house at the night rate. In other cases, the length of the burning is enough, so as not to run into the boiler room among the nights in order to throw firelines.

Copper with upper burning fuel

In the post-Soviet space, these heat generators are known in two varieties:

  1. Baltic aggregates of the company "Stropuva" and their derivatives from other manufacturers.
  2. Woody stoves like "bunch".

It is not known which of the heaters earlier, but the bunch of the bunch has won wide popularity as a heater for cottages, garages and other buildings with low product aesthetics requirements. What can not be said about the boilers of the upper burning, although many of them for some reason consider the only possible version of solid fuel heat generators of prolonged incineration. In fact, their only trump card is all the same - a large-sized fifth.

The principle of action of such boilers is to burn the fuel attached by the cargo in the direction from top to bottom. Moreover, the air is supplied to the burning zone is also on top, along the telescopic tube connected to the load. The working circuit of the unit is shown in Figure:

STROPUVA heat generator device - schemeOriginal boiler scheme taken from Stropuva.ru

In the process of operation of STROPUVA boilers, many flaws were manifested, as evidenced by the reviews of the owners on the forums:

  1. It is impossible to throw in the firebox of the lane, until the previous bookmark burns. Physically, it is possible, but then the principle of the upper burning will break, the flame will cover all layers of fuel.
  2. When working on fresh sawdust and other small garbage, fuel residues "hang" on the walls.
  3. The effectiveness of the TT-boiler is not too high, since it does not have a heat exchanger. Due to the air heating chamber and a large fuel cell for the heat exchanger, there is no place left.

There is no more critical flaws from the heat generator, and something in the homemade version can be corrected in its understanding. For example, put the bottom and grate, organizing an ash chamber. You can get rid of a lack of a fitting device, if you put an additional door between the loading and ash opening. This idea of ​​upgrading the upper burning boiler belongs to another expert - Vladimir Sukhorukov, what he tells about in his video:

Watch this video on Youtube

Preparation of materials

The round case creates some inconvenience in the manufacture, but you can't do it square, the fuel will "hang" in the corners. There is a problem and with the assembly of a telescopic pipe with a cargo, so that this part is better to take from the bunching furnace. Drawing of a long-burning boiler, comparable in size with a classic version, looks like this:

Drawing of the upper burning boiler in the context

Before making a boiler, we select materials according to the drawing:

  • pipe DN 400 with a wall of 5 mm - on the fuel cell;
  • The same, DN 50 - on air supply and water nozzles;
  • The same, DN 100 - for chimney;
  • Billet from a leaf of a thickness of 10 mm round shape with a diameter of 38 cm;
  • strip 40 x 4 mm - for air distributors;
  • Armature with a diameter of 16-20 mm of a periodic profile - to grate;
  • Basalt wool 3 cm thick and 100 kg / m³ density;
  • Polymer metal coated metal.

The choice of water shirt material depends on the method of its installation, because the domestic master is unlikely to be in stock rollers, capable of making metal with a thickness of 3 mm. Options are (are shown below in the diagram):

  1. Scheme number 1. Take a thin-walled pipe of a larger diameter, although it is not easy to find such, and the usual drowned the boiler.
  2. Scheme number 2. Two metal sheet bend in 2 places at an angle of 60 °, and then cook two halves together. It will take a press listogib.
  3. Scheme number 2 in another execution. Cook a shirt of 6 sheets - segments on clips.
  4. Scheme number 3. Cook a rectangular box, which will increase the volume of the boiler tank.

Round Boiler Water Shirt Production SchemesScheme number 2 can be implemented in two ways - cook from 2 bent halves or 6 flat sheets

Also need a sheet metal 3 mm on the framing of the door, the bottom with the lid and the air damper.

The production of work begins with cutting blanks and openings in the pipe wall in size in the drawing. Doors are made from the cut parts, sheds and purchased handles are fitted. From the reinforcement, the grate grille shown in the photo:

How to make a grate of the armature grid

In general, the algorithm for assembling the boiler of the upper burning looks like this:

  1. In a round billet for cargo cutting hole, insert a pipe into it and ribbon.
  2. To the lower part of the cargo, welcome 6 curved bands, which will serve air distributors.
  3. Attach the bottom of the bottom, set inside the grate.
  4. Cutting a hole in the center of the cover for the air pipe, to adapt it to the fuel. Before that, you need to put the pipe with the cargo in place.
  5. Siggle the flue of the chimney.
  6. Mount the water shirt on the selected scheme, hermetically rolled all the joints.
  7. Conduct the cutting of the pipes for the coolant.
  8. Perform insulation and boiler trim, install doors.
  9. Put a damper on the top of the air pipe.

Air supply pipe in TT-boiler with top burning firewoodFor air distribution, it is enough for six lanes-distributors

Installing automation and superimposed on the boiler for a long-term upper combustion is difficult, because the fan will not stick to the moving pipe. It is necessary to make a flexible sleeve, and for the temperature sensor to provide a submersible sleeve. It is impossible to invest it under the insulation, because the burning zone in this form of heaters is constantly shifted down.

Overview of solid fuel boilers

The decision to make a self-made boiler puts the task to get acquainted with various variants of devices and choose the most suitable. It is necessary to take into account not only the power and the possible display of the efficiency of the boiler, but also their strength. Without special construction skills, it is necessary to stop at the simplest, in the presence of experience in the manufacturer, you can swall ash on the model more comprehensive, or improve simple options for greater convenience and utility.

Make a picture of the variety of options boilers is very important. Reviews about purchased models often indicate their ineffectiveness. It is necessary to understand that usually the small efficiency is not connected with the characteristics of the device, but with improper installation and heating.

Classic wood boilers

Classic, or the standard option, simply arranged. It consists of parts such as:

  • Fire. In other words, the part in which firewood gets.

Attention! The volume of the furnace indicates the total power of the unit, both in the homemade and purchased models.

  • Solnik. The ash remains there, as well as this part serves to supply air required for burning.
  • Chimney. This part is required to remove gases. An important factor is its diameter. With the wrong selection of the Diameter of the efficiency, the efficiency is significantly reduced.
  • Heat exchanger. In the classic boiler, this area between the case is external and internal. The heat exchanger is filled with water, this water is tied with water in the heating system.

Top-burning heater

Such heaters are arranged on the principle of classical, but they have no ash bar. Instead, it has a peculiar gas feed, which helps helps to conveign not only the burning energy, but also the energy of the formed gases. Usually there is a fan in the gas feed. Thus, two different energies affect the heat exchanger, providing greater hours and increase efficiency. In a different way, this type of boilers are called pyrolysis.

Pyrolysis models

The principle of operation of a long-burning boiler is the separation of heat from the energy from the burning of firewood, but from gas that is formed when they are considered. It is quite convenient and provides heating for a larger time period.

From the classical model, such have a number of differences, for example:

  1. It is possible to adjust the power. There is an opportunity to speed up and slow down the flow of incoming air, which affects the power. In the classic, only the volume of heat combustion chamber affects the capacity
  2. Low-temperature mode of operation is possible. This significantly reduces the wear of the system.

Note! In classic boilers, the water temperature reaches 95 degrees and above. This is considered ineffective. In the pyrolysis model it is possible to achieve a temperature of 50-70 degrees, which is considered optimal for heating.

  1. Fuel combines almost completely. Due to the peculiarities of the device and the principle of operation in the pyrolysis boiler, contamination of the chimney decreases, the firewood is combined entirely.

Two-chamber

Mine heat generator

Mine unit works longer than standard pyrolysis. This is due to the fact that it usually is volume and massive. Mine boilers work both according to the usual principle and by pyrolysis.

In their device, two cameras are one for the heat exchanger, and the second fuel. When working on the usual principle of combustion, the fuel chamber is usually called the mine. It is from here that is the name. There are valves between cameras, the device also has pipes for a gas feed and air intake.

Such a heat generator is perfect for those who do not like to put fuel often. One maximum laying of firewood is enough for a 30-hour heating process, and one coal laying is 5 days.

Of course, when it comes to how to make a heating boiler, it should be understood that for the manufacture of such a design you will need certain skills and experience with instruments.

Step-by-step instructions for creating a solid fuel boiler for long burning with their own hands

The project of a solid fuel boiler - the task is not easy and new to cope with it will be not easy. Before proceeding with construction, prepare drawings and sketches.

Drawing of homemade solid fuel boiler

Drawing of homemade solid fuel boiler

Prepare also the following tools:

  1. Welding machine.
  2. Metal Tools: Pliers, Grinding Circle.
  3. Electric drill.
  4. Construction level and roulette.
  5. Marker.
  6. Bulgarian.
  7. Gloves and protective screen on the eyes.

Attention! When performing work on the manufacture of a homemade TT of a continuous burning boiler, you should be very careful and have at least basic practice with the welding machine. Use sure to protect when working with welding.

Materials will need:

  1. Empty gas cylinder.
  2. Sheet metal.
  3. Asbestos cord.
  4. Steel pipe with a cross section of 60 mm.
  5. Metal loops and handles.
  6. Metal corner or blade.
  7. Metal hood.
  8. Basalt fiber for the passage of the chimney pipe.

Before the start of the manufacture, we suggest you will get acquainted with the video instruction, how to correctly cut an empty gas cylinder, look carefully and do not neglect the safety measures!

Step 1. Marking of the case and the manufacture of the case

With the help of the marker, perform marking on the propane cylinder according to the drawing size.

We make a small rectangular hole under the doors of the ashtar, through which the boiler cleaning will be carried out.

On the upper part of the cylinder (throughout the perimeter), we carry out a flat line for the slice cut.

With the help of a grinder, cut off the top.

Cutting the top of the cylinder

Cutting the top of the cylinder

Now in the center we carry out the markup under the hole through which the pipe will pass. The hole, respectively, should be larger than the pipe diameter.

Cut the hole in the lid and weld the metal ring, which will be tightly wrapped the pipe inserted into the cylinder.

Weld the ring in a circle

Weld the ring in a circle

Watering with a small ring of sheet metal (4-5 mm) from the external and inner side of the balloon itself, to which the lid will be put on.

Step 2. Pipe Production

We take a metal pipe from 80 to 100 cm long. If you are using a non-propane standard cylinder, and independently boil the housing for the boiler, consider that the pipe height must be 20-25 cm above. After all, the essence of the work is that as the fuel is roasted, the pipe inside the case will fall down.

We weld to the pipe at its lower part metal circle - air distributor.

Cutting the top of the cylinder

Cutting the top of the cylinder

Cut from the sheet metal mounting, which are securely weld along the clarification line, pre-roof asbestos cord.

Weld the handles to the lid

Weld the handles to the lid

Cropped cut-off top so that it is easily shot and put back. Perform the handle metal and for ease of removal, also weld them to the case.

Step 3. Production of a nozzle to chimney

We make markup on the cylinder in the upper part of it under the hole of the nozzle.

We weld the pipe

We weld the pipe

Cut with the help of a grinder and weld the pipe to output combustion products.

Then the steel chimney pipe joins this pipe.

Step 4. Making asolnic

On the previously made markup under the ash chamber, cut the hole with the help of a grinder.

Cut the zolnik

Cut the zolnik

Separately from the sheet metal, we carry out the door, which then you need to fasten to the brackets to the boiler body.

Hole under the door of the ashbar

Hole under the door of the ashbar

For convenience, you can perform a small loop of thick wire or reinforcing rod and fasten as a handle.

Step 5. Cooking the air supply system

Measure the inner diameter of the cylinder case. Now on the sheet metal, draw the circle, the diameter of which will be 5 mm less internal diameter of the cylinder.

With the help of a grinder cut this circle.

So the air supply system looks like

So the air supply system looks like

We take a metal corner and cut it into 6 equal parts. The size of each part is ½ diameter of the metal circle. For these purposes, the impeller with old blades is still well.

Making the air supply system

Making the air supply system

We weld the metal circles in the same direction counterclockwise.

Step 6. Make the heat exchanger

We will make a heat exchanger designed on the principle of water circuit.

Making heat exchanger

Making heat exchanger

The size of this heat exchanger depends on your personal preferences. What it will be more, the greater the number of firewood you can lay on it, which means that your boiler will be distinguished by the greater burning.

From a sheet metal with a thickness of 5-6 mm, cut out sheets according to the scheme and weld them into a reliable housing, inside which our gas cylinder will be located.

In the upper and lower part of the housing, perform nozzles for connecting the feed and reverse line.

In the central part it is necessary to provide a hole through which fuel will be laid. We perform with a marker markup and cut out the grinder.

Step 7. Total assembly and installation of boiler

Fresh the coat of the roller on the furnace.

We note on the heat exchanger housing, the place where access to the ash tank will be made and cut out with the help of a grinder. We also equip this opening door, which should be very tightly closed, blocking oxygen access to the case.

Collect the boiler

Collect the boiler

Insert the cylinder inside the heat exchanger.

With the help of a welding machine, you brew the pot from above, as a result of which we get an absolutely sealed case, inside the round firebox.

The essence of the TT of a long-burning boiler consists in limited air supply from above, the function of which performs the oxygen supply system.

Fuel (firewood, coal, briquettes) should be loaded very tight so that there are as few spaces between the layers. If the firewood is different in size and tightly, it does not work, then between the layers can be filled with a chips, paper. The more denser this solid fuel mixture will be, the longer the firewood will burn.

Booting boiler should be dense

Booting boiler should be dense

How will this boiler be loaded?

  • Give the air supply limiter from the case;
  • We load fuel through a special door. Fuel is pre-splashing to sprinkle with a special fluid for ignition;
  • put back the pipe limiter;
  • Inside the boiler throw a lit match;
  • After you make sure that the fuel gradually begins to smooth, cover the door tightly.

As the firewood is roasted, the pipe inside the cylinder will gradually fall. At its height, you can always find out how much firewood is now inside.

Step 8. Motor of the Boiler

Such a simple boiler you can perform right on the street in the warm season and test it outdoors, equipping by temporary chimney.

Merging boiler

Merging boiler

If the area of ​​the room exceeds 30-40 square meters, then two cylinders can be cooked vertically, zooming, thus laying firewood.

Step 9. Installation of the boiler indoors

Take away very seriously to the fire safety of the boiler.

It is better to highlight a separate room or make a small fence from tenants to eliminate burns. Still, the housing of the boiler is metallic and unlike a stone oven, there is a high probability of getting a burn.

Install in the place where it is possible to find the chimney. You can remove the chimney in two ways: through the roof or through the wall.

Consider that you need direct access to the boiler, so at a distance of 50 cm next to it should not stand.

  • Perform a brick base under the boiler, putting a solid brick in 2 rows. Check the building level of the base.
  • Observe the distance from the walls (regulated by SNiP). From the furnace door to the wall, the distance should be at least 125 cm. The distance between the side parts and the back side of the boiler and the wall should be at least 700 mm.
  • If the walls in the house are made of wood or any other combustible material, it is necessary to protect the leaf metal or basalt space of the boiler adjoining to overlaps. It is possible to use the usual brick as thermal insulation, which should be put on the perimeter, the place of the boiler adjustment to the wall.

At the output of the chimney through the wall or roof, it is also necessary to ensure proper thermal insulation. To do this, basalt fiber is suitable, which should be tightly paved between the chimney and overlap.

  • Install the boiler on the prepared foundation and check the level as far as the device is worth it. Consider that the gas outlet should be on the same level with the chimney pipe. If the line is horizontal, then the thrust may be broken during operation.

Step 10. We connect the boiler to chimney.

Attention! It is necessary to lubricate the joints of the joints of the compounds of all parts of the chimney among themselves.

Connect the chimney pipe to the nozzle TT boiler. The diameter of the chimney should be no less than the pipe TT boiler. If these parameters do not comply, then the gas output throughput will be reduced.

Connect to chimney

Connect to chimney

As you can see, doing everything with your own hands, you can get excellent, everything is not so difficult as it seemed at first glance! If you clearly follow the instructions, then quickly evaluate the high performance and efficiency of a solid fuel boiler for long burning, which at times exceeds its competitors with the Open Flame principle. This will allow to maintain a comfortable microclimate in the house with minimal care.

Woodwood water boiler

For its manufacture we will need:

  • Protective gloves;
  • Overalls;
  • Welding mask;
  • Electrodes;
  • Welding machine;
  • Drill;
  • Metal drills;
  • Roulette;
  • Material for the manufacture of boiler (2 barrels or - metal sheet (thickness - at least 5 mm), doors, dampers, grille, corners)

    The only substantial lack of a wood boiler is low efficiency. But simplicity of manufacturing and maintenance is essential advantages that makes it the most popular.

Installation of wood boilers in the heating system

Independent manufacture of the boiler implies the presence of skills and experience in the production of welding, electrical and plumbing works. Knowledge of physics, heat engineering, materials science, installation rules of heating systems.

It is necessary to comply with the techniques and safety techniques. To assemble the boiler, an equipped room and tool are needed.

Material for the manufacture of pyrolysis boiler:

  • Sheet steel thickness 6, 5 and 4 mm (firebox, heat exchanger shirt and body);
  • Corner with sides of shelves 50 mm (rigid rigid rigid);

Two-round solid fuel boiler with accumulative hot water tank

  • steel pipe (heat exchanger strapping with heating system);
  • Suitable in the size of a cast iron grate or rod round with a diameter of 20 mm;
  • chammatory brick;
  • centrifugal fan;
  • Ready doors with reflector, fastening, handle and constipation;
  • Security group (temperature sensor, pressure gauge).

Welded parts are marked with chalk (place of connection, part number, dimensions). Specialized organizations offer services for cutting material at the place of acquisition.

Tools for the manufacture of boiler:

  • DC welding machine;
  • electrodes (diameter 3 ÷ 5 mm);
  • electric drill;

Connecting the heating boiler

Connecting the heating boiler

  • corner grinding machines (under a large 230 mm and small 125 mm circle);
  • Chatter, roulette, level.

The assembly of the boiler starts from the inner case. The quality of welds should ensure the strength and density of the structure, which is in direct contact with the coolant.

Instructions for manufacture

When there is everything you need (material and tool), it remains only to assemble the boiler in such a sequence:

  • We take 2 barrels with different diameters, the thickness of the walls of at least 4 mm;
  • Bulgarian cut the holes under the ashpan and water container;
  • We establish one cylinder of a smaller diameter in the other;
  • We weld the cover above them, the roller, the furnace;
  • Close the door;
  • We weld the water pipes, the nozzle for the check valve (discharge of pressure);
  • Inside the furnace mount the lattice;
  • We make a hole for chimney;
  • Install the pipe;
  • Check tightness.

When there are no leaks in the boiler, it is connected to the heating system and a water supply network.

If the coolant is exhaust oil or antifreeze, then they will be poured manually. Connections to the water supply, welding nozzles for this not need.

After installing the boiler with your own hands to the heating system, you need to check the correctness of its work. The correctly assembled device will heat the coolant (water or oil) during fuel combustion. If he does it badly, then you should check the presence of air traffic jams in the heating network, reduce the pressure of the vapor due to their discharge.

In any case, it is necessary to understand the principle of operation of this kind of boiler so that there are no excesses and problems in the process of its operation.

Installation of boiler and commissioning

To ensure a sufficient degree of air circulation, the homemade heating boiler on firewood must be installed on 20 -30 centimeters above the floor level on a refractory foundation, welding to the base of the unit steel legs.

Connecting the device to the heat supply system is carried out in two stages:

  1. Feeding and recycling pipes are connected to the housing using nozzles.
  2. Pipe smoke angles cras into a water tank.

Before connecting a standard or mini-boiler on firewood, a brick screen is built around it, increasing the efficiency of heating and providing protection against contacting the hot metal surface at least 30 centimeters.

маленький котел на дровах

The sequence of the unit introduction to work:

  1. From the boiler removed the lid and the heat dissipation disk.
  2. A thermal damper opens on the air duct.
  3. Firewood is not higher in the furnace compartment, firewood is stacked, on top of which small chips should be poured.
  4. Before extracting firewood is poured by a small amount of liquid intended for ignition.
  5. The boiler is covered with a disc and closes with a lid.

When the firewood is spoiled, the damper is covered.

Ordinary boiler

First we will analyze how to make a simple wood boiler with your own hands. The model is two cylinders placed in each other. The first is used as a firebox. With a horizontal arrangement, it can end the refractory brick from the inside.

The second acts as a convection carrier or is used to heal the coolant. The firewood tab is made directly to the furnace.

Screw materials

To reduce the volume of welding, you can use a thick-walled pipe or barrel. It is also possible to use other healthy materials.

A rectangular firebox welded from a thick sheet can be easily placed inside a cylindrical container.

Design features

In a woodcut, the boiler is encouraged for the influx of fresh air and chimney for removing the exhaust gases. Standing is located at the bottom of the pipe and allows the lower row of firewood, producing additional heat. Stamp on firewood in homemade boilers is performed through the top. For this, a special hatch is prepared.

Котел на дровах

To each laid stack of firewood burned as long as possible, it is often a special cargo performed in the form of a disc with blades and a hole having a diameter of 20 mm. Under the pressure of the cargo there is compressing burning fuel. At the same time, the volume of incoming air is significantly reduced, as it can only pass through the available hole.

Connection method

To the heating system, such a boiler can be connected in two ways:

Котел на дровах

  • Cutting the pipe with water right in the barrel. Circulating between the pipes, it will heat up to then enjoy the heating, heat the radiators;
  • Cutting the chimney into the tank with the coolant. The spent hot gases will flow into the container, gradually heating the coolant.

Using electric boilers

Котел на дровах

Diagram of installing an electric boiler in the heating system.

In order to heat all the housing with the help of electricity, a boiler is installed, which heats the water to a certain temperature, and then it circulates through the heating system by means of a coolant. Many believe that the installation and use of such boilers is an uneconomic option for a private mansion.

In this case, gas, compared with electricity, is much more practical, but this is if there is accessibility to the gas highway. Although the installation of gas equipment and service of gas boilers pays off for a very long time.

The main advantages of using electric boilers:

  • convenience in the operation of equipment;
  • Fast heating at home;
  • temperature adjustment;
  • Installing equipment at any time of the year.

The principle of operation of the electric boiler is practically no different from the gas heating system. The difference lies in the fact that water heating occurs by means of Tannov, not gas. At the same time, heat throughout the residential premises occurs similarly, as with gas heating, that is, in the pipeline with the help of the coolant.

Conclusion

On the one hand, the installation of a solid fuel water boiler - the procedure is quite simple in execution, harsh requirements for it is not extended and permits from officials is not required. On the other hand, the process of troublesome and time-consuming, associated with thousands of small nuances. However, the homeowner always has a choice: perform all work independently or give some part (for example, strapping) trained personnel by a specialized company.

With a thorough and correct study of the drawings of solid fuel boilers it is possible to make a long-term burning boiler with its own hands with reliable and economical.

Solid fuel boilers have already become considerable popularity, although they have one significant minus - they need constant fuel load (coal, firewood, etc.). Because of this, the shortage of them is often refused when the heating system is arranged, but it is easy to get rid of it - to make a length of long burning with its own hands, functioning almost on all types of fuel (extremely solid, of course).

How the homemade boiler of long burning is arranged

Principle of operation

The scheme of such boilers is based on the features of solid fuel to smoke a few hours, producing a large number of thermal energy. It is characteristic that the fuel in this case is burned more fully, and the amount of waste, as a result, is noticeably reduced.

Drawing of the boiler
Drawing of the boiler

Note! Replacing active incineration is possible due to a special device of the heating boiler.

The main element of the boiler is the furnace, where the burning is limited, and the air supply intensity is controlled using special devices. The fuel is loaded twice a day with large portions, after which it slows slowly (the limited amount of oxygen does not allow it to be fully lit).

The pipe by which the smoke is derived is passed through the heat exchangers and heats the fluid in the heating system. It turns out that only every 12 hours load fuel for uninterrupted heating at home.

Cottage scheme

Main advantages

Long burning boilers are highlighted against the backdrop of the heating systems of other types. Of course, the main advantage is the duration of work, but there are other important points:

Device device

For the manufacture of the boiler, it is more convenient to use the metal pipe Ø30 cm and more with a thickness of the walls of at least 5 mm (otherwise the latter will soon run out due to the high temperature inside the device). The height of the design may vary between 80 cm and 100 cm, it all depends on the area of ​​the room.

Pipe for housing
Pipe for housing

Regardless of the modification, the boiler consists of three main zones:

  • boot zone;
  • zones of tensions and heat generation;
  • The zones of the final burning where the ash is lit and smoky gases are derived.

Note! The device that limits the loading zone and, accordingly, the time is called the air distributor.

This element is performed as a metal circle with a thickness of 5-6 mm with a hole in the middle, through which the oxygen is supplied using a telescopic tube. The diameter of the product must be somewhat less than the diameter of the case. Height is adjustable by means of a special impeller.

Ask a question expert

Typically, the burning zone does not exceed 5 cm in height - if it is greater, the fuel will burn too quickly. By the way, the oxygen tube can be not only telescopic, but also whole. Its diameter is usually 6 cm, while the size of the opening in the air distributor does not exceed 2 cm, in order not to please the oxygen zone.

Copper long burning
Copper long burning

Air can be served one of two ways:

  • straight from the atmosphere;
  • From the special heating chamber (it is located in the upper part of the design), which provides a more efficient operation of the boiler.

For adjustment, a special air damper is used.

A chimney tube is welding from above. It should be carried out perpendicular to the corpus at least 0.5 m, otherwise excessive traction is formed.

The bottom is equipped with a door to remove combustion products. Cleaning must be carried out infrequently, because the fuel will be completely burned.

There are two ways to heat the coolant, each has their own strengths and weaknesses.

Make such a design at home is easy, but this will require the skills of working with the welding machine and clear instructions.

Stage 1. Preparation of all necessary

For the manufacture of the boiler will be required:

After training equipment and consumables, you can proceed to work.

Stage 2. Build construction

Note! The boiler must be installed on a flat surface. If required, a concrete base is equipped (everything depends on the total weight of the structure).

The sequence of action when assembling is as follows.

Step 1. The pipe that serves as a construction hull is trimmed in accordance with the selected length (from 0.8 to 1 m). If the length is greater, it will make it difficult to load fuel during operation. The bottom of the sheet steel is welded and (if required) the legs made from the chapellera.

Assembling the heating system

From a simple boiler, where a full air supply is necessary throughout the volume of fuel combustion, the construction of long burning, as noted earlier, is distinguished by limited this feed. Moreover, the loading volume directly affects the combustion time, so in our case the furnace is loaded extremely tight so that the gaps remain.

Step 1. Removed upper construction cover.

Step 2. An air regulator is extracted.

Step 3. The boiler is loaded with fuel in the level of chimney pipe.

Step 4. From above, the fuel is poured by a small amount of liquid for ignition (diesel oil, worked out and solar.).

Step 5. The air regulator is installed back, the cover is put on top.

Step 6. Air damper opens to the limit.

Step 7. The piece of paper is ignited, rushes inside the design. When the fuel starts to smooth, the air damper closes.

Therefore, permanent burning began, can be judged by the smoke that appeared from the chimney pipe. As the fuel burning, the pipe smaller diameter will be lowered along with the air regulator - on this peculiar indicator and you can determine the amount of the remaining fuel.

As a conclusion

The boilers described are used not only for heating houses, but also with winter heating of hlev, sheds, greenhouses, etc. If the assembly and installation works were carried out correctly, the device will function in economically and absolutely safe, and solid fuel can be used, including household garbage.

In addition, boilers do not need constant control, it is necessary only in practice to determine the time interval between downloads. It should be remembered that the combustion time depends not only on the volume of the structure, but also on the type of fuel.

The most optimal source of heating for remote areas without gasification and electrification is a solid fuel boiler for long burning. Thanks to reliability, efficiency and efficiency, it is often used to equip country houses and cottages.

How the aggregate works

Conventional solid fuel boilers are able to work on one bookmark about 6-7 hours. If after this time in the furnace is not to throw another portion of fuel, it will lead to a decrease in temperature in the house. The reason lies in the circulation of the main heat indoors on the principle of free air movement: after heating, it rises up and goes into the street. The heat resource of one laying of firewood of a long-burning device is designed for 24-48 hours. In some models, burning is supported for almost a week.

The secret here is as follows: Unlike traditional boilers, the diagram of a long-burning boiler includes not one, but two combustion chambers. The first of them is intended for burning fuel, the second - for the gases received from the first chamber. The quality of the process largely depends on the timely air supply, for which there is a fan in the design. Such an approach is innovative: it was first introduced by the Lithuanian company STROPUVA in 2000, after which the drawings of solid fuel boilers of long burning were adopted by leading manufacturers of boiler equipment.

Solid fuel boiler with his own hands drawings

To date, the aggregates working on this principle are the most inexpensive and practical option for heating houses in areas devoid of gasification. The essence of the devices of this type is the burning of the upper fuel. Typically, the location of the furnace is the lower part: as a result, the cold air after heating has the ability to rise up. Long burning boilers are very similar to pyrolysis: the release of the main portion of heat is not due to the combustion of solid briquettes, but from the gas distinguished.

For combustion inside the design there is a special closed space. The chambers are interconnected by a telescopic tube, according to which the gas separated from the first branch comes into second. The process of its survival is accompanied by mixing with cold air, an injected fan. This procedure stems without pauses, until the fuel is complete. It is characterized by a rather high temperature regime - up to +1200 degrees.

The chamber for burning solid fuel has more extensive dimensions: its volume sometimes reaches 500 dm 3. It can load coal, sawdust, firewood, pallets. Stable air injection is provided by a built-in fan. The combustion process is characterized by a very slow fuel consumption rate. As a result, the efficiency of boiler equipment increases sharply.

The reason for slow burning lies in the injection of the air, as a result of which only the upper part of the fuel laying is roasted. An increase in air supply takes place only after the top layer is complete. There are a number of heating devices on sale, the essence of which is the same drawing of a long burning boiler on firewood. Different degrees of their economy and efficiency are explained by differences in the size, manufacturing materials and the presence of additional functions. To work universal TT boilers, you can use any fuel, which greatly simplifies their maintenance. The most cost-effective models are the wood tt boilers.

Construction Features and Device

The camera for laying fuel of any long burning boiler is distinguished by impressive sizes. This parameter directly affects the flourishing time of the fuel laying. Currently, there are two successfully competing technologies implemented in TT boilers: it is about the devices of the buleryan and a sling. Dorganiza and the complexity of manufacturing a drawing of a long-burning boiler makes certain obstacles to the dissemination of the last of them in our country. Unlike him, the buleryan method is widely used by folk craftsmen for an independent organization of the heating of country houses.

The drawing of a boiler's long burning boiler on solid fuel consists of the following nodes:

  1. Metal case closing internal chambers.
  2. Lower chamber for burning fuel.
  3. Top chamber for burning gas.
  4. Doors to bookmark firewood. It is located in the upper part of the design due to the large size of the lower compartment for booking the resource.
  5. Smoke nozzle. It is in the top of the boiler and is connected to chimney.
  6. Solo camera. Located at the bottom of the boiler and is intended for its cleaning.

homemade long-burning boilers

There is also another curious detail. As you know, in conventional furnaces, the function pondered by a ash-like: it is through it that the air required for burning. In the case of a buleryan, the ash compartment is made completely sealed: the air supply channel here is the upper air chamber. To adjust the oxygen supply at the top of this chamber there is a damper. In the course of the combustion of firewood in the furnace gradually settle, which leads to lowering the distributor. This ensures a continuous supply of fresh air.

To implement a new load, the distributor can easily be returned to the initial position by pulling it up. The position of this lever serves as a peculiar level of the level of the remaining fuel: in this way, you can determine how much loading the following portion of firewood. Boilers of the buleryan features high ecology, which is explained by a complete blow of fuel and gas: carbon dioxide in the atmosphere practically does not fall. See also: "How to make a boiler on firewood with your own hands - step-by-step instruction."

The device of a solid fuel boiler for long burning as follows:

  • Fire. The main structural element of any boiler or oven. It is intended for burning fuel in it.
  • Department for download gas. Here the gases arrived from the furnace.
  • Solnik. Coupling to assemble ash. It needs regular cleaning.
  • Chimney. Channel for a lead from the branch of the combustion products.

Strong and weak sides

Large dimensions and difficulty performing the drawing of a solid fuel boiler for long burning makes it favorable to use such devices only in large cottages. As for small cottages, it is recommended to choose more economical options for them.

The main advantages of TT boilers of long burning are:

  • High efficiency (about 95%)
  • Autonomy of heating.
  • Efficiency.
  • Reliability and durability.
  • High efficiency.
  • Availability of fuel.
  • Ecology.
  • Wide selection of fuel (coal, firewood, sawdust, pallets).

Long burning boiler drawings on solid fuel

There are also disadvantages:

  • Large dimensions.
  • The need for equipment of a separate boiler room.
  • A complex device of a long burning boiler on firewood.
  • Need in constantly maintenance.

The boilers of this type have a fairly decent cost, but such structures can be manufactured independently.

Advantages of homemade units:

  1. Cheapness.
  2. Universalism in terms of fuel used.
  3. The possibility of subsequent improvements in order to increase the efficiency and addition of power.

The most difficult thing is to make a cylindrical design: for this you need to use a rolling machine. If it is not, there is an option with old propane cylinders. Any pipe of the appropriate section will also be consolidated: the thickness of the metal walls should be at least 5 mm. In the villages were accustomed to be satisfied with small brick furnaces, demonstrating good effectiveness when heating single-storey houses and cottages. If you need to give a vast cottage, then in this case you will need a large fuel reserve. In addition, not to avoid large temperature drops as it removes from the furnace, and it is much more complicated to care for it than for a solid fuel boiler.

Recommendations for the manufacture of homemade boiler

Getting Started by the manufacture of a long burning boiler with their own hands, it is necessary to arm the following tips:

  • In order to use any fuel in the process of operation of the appliance, it is better to make firecase from heat-resistant alloy steel. Some of the work budget helps the use of seamless steel pipe brand 20.
  • Before you make a homemade unit into a boiler house prepared for it, it is recommended to test it on the street, equipping by temporary chimney. This will give the opportunity to check the reliability of the heater and make sure that the body assembly is correct.
  • The main chamber made from the gas cylinder is able to provide a duration for 10-12 hours, because Firewood in it is a bit. Initially, the small inner space of the propane cylinder decreases after removal of the lid and the ash bar. To increase the parameters of the boiler, it can be made of two cylinders. This will obtain a fairly large flue chamber for heating extensive premises and increase the time between the wood bookmarks.
  • The zolnik door must be sealed to close, which will not give the outer air to seep inside the chamber. This is achieved by styling around the perimeter of the doors of asbestos cord. If the boiler has an additional door to make the fuel without removing the lid, it is also sealed in a similar way.

Drawing of a long burning boiler with their own hands

Standard solid fuel uses firewood, anthracite, sawdust, briquettes, peat, stone and brown coal. Special complaints about fuel quality are usually not presented. However, it is desirable that the fuel material is as dry as possible, which will give a high efficiency warranty.

Safety regulations

To achieve good efficiency, durability and efficiency of homemade boilers of long-term combustion, during their operation it is necessary to comply with the basic fire safety recommendations:

  • Watch that the temperature inside the contour does not exceed the boundary indicators.
  • The feed pipe is prohibited to equip the lock valve.
  • In the immediate vicinity of the boiler should not be stored flammable materials.
  • Ventilation in the room should be fully serviceable.
  • The device can only be installed in a separate room (boiler room). This moment is thought out during the implementation of preparatory activities.

Drawing of a solid fuel boiler for long burning with their own hands

The equipment of the boiler room is the best option, since TT boilers work are somewhat different than ordinary furnaces on firewood. In addition, an externally, the device does not represent aesthetic interest, and most likely will break the overall interior. Since the use of solid fuel is accompanied by the appearance of dirt, it is best to install the boiler in a non-residential room.

Small instruments with a capacity of no more than 35 kW are allowed to place in the main room: For convenience, the installation location can be protected by a brick simple. The room where the boiler will be located, must have good ventilation. It is very important to organize a stable inflow of oxygen from the street.

How to make a solid fuel boiler for long burning with their own hands

Tools will be needed for work:

  • Welding machine.
  • Metal processing devices.
  • Electric drill.
  • Level and roulette.
  • Marker.
  • Bulgarian.
  • Gloves and eye protection.

Drawings of solid fuel boilers of long burning

It is recommended to start a similar procedure only to people who have at least a little experience in handling welding and know how the pot of long burning is arranged. The presence of special protective clothing is required.

It is also necessary to prepare such materials:

  • Empty gas cylinder.
  • A metal sheet.
  • Asbestos cord.
  • Steel pipe with a diameter of 60 mm.
  • Metal loops and handles.
  • Metal corner and extract.
  • Basalt fiber.

Work on the hull drawings

An empty propane cylinder is equipped with marking, according to the drawings of a solid fuel boiler for long burning with their own hands. A rectangular hole for the cooker doors is made designed to remove the ashes. On top of the cylinder around the circle, a smooth line under the cut cap is carried out: pruning is carried out using a grinder.

устройство котла длительного горения на дровах

In the central part, the markup of the niche for the output of the chimney is performed: the dimensions of this hole must exceed the cross section of the pipe. A hole is made in the lid and a metal ring is welded, a tightly clamping chimney channel. Metal ring with a thickness of 4-5 mm is used to deter base from the inside and outside. It will later dress the lid.

Chimney at the bottom is equipped with a metal circle that performs the function of the air distributor. The fasteners are welded along the cylinder cut line over the pre-padded asbestos cord. When attaching a cut top, it is important that it is freely shot. For convenience, it can be equipped with a metal handle.

Chimney pipe

In the upper part of the cylinder, the hole is planned under the nozzle, according to the drawings of the solid fuel boiler with their own hands. For cutting the chimney pipe, the Bulgarian is used: welding the nozzle over the cut hole, dress the main chimney body.

Solnik

An previously applied markup is used to cut the screw hole. The door is made separately from the sheet metal: its fixation on the body of the brackets. In order for the door to be convenient to open and close, it is equipped with an improvised handle from a metal rod or thick wire.

как устроен котел длительного горения

Air supply system

Armed with the parameter of the inner diameter of the cylinder, it is transferred to a metal sheet, reducing 5 cm. The grinding circle is cut on the applied markup. Next, six equal segments are made of metal corner, the length of which should be ½ diameter of the circle. In this capacity, you can apply an impeller having sharp blades. When welding metal elements, it is important to maintain the same direction.

схема котла длительного горения

Heat Exchanger

In the manufacture of the heat exchanger, the easiest way to use the principle of water circuit is the easiest. Selecting its parameters depends entirely on the wishes of the wizard. The sizes of the heat exchanger will directly affect the volume of fuel loaded at a time: the more, the longer the pause between the wood bookmarks. For the manufacture of the body of the device, metal sheets are used with a thickness of 5-6 mm: they boil them well at all joints. The upper and lower part of the housing is drawn up with nozzles for switching the feed pipe and returns. The central part must have a hole for fuel loading.

Final assembly and installation

In order to install the cooker's door, on the housing first need to be outlined and cut a niche for accessing the camera. Next, this opening is mounted a hermetically closing door. The balloon is inserted into the heat exchanger. Using the welding machine, the tank carefully boils from above: this makes it possible to achieve the absolute tightness of the body, with a round-shaped furnace.

During the operation of the homemade boiler for long burning with water circuit, it is important to achieve a dosed air supply. The fuel is loaded as close as possible: the emptiness between the layers should be minimized. It happens that the thick laying of the lane of different sizes is difficult: in this case, the remaining niches are filled with paper or chips. The density of the solid fuel bookmark does not directly affect the duration of its burning.

чертеж твердотопливного котла длительного горения своими руками

The order of fuel loading in TT boiler:

  1. Initially, you need to remove the air supply limiter.
  2. To lay the firewood through a special hole, having previously lubricating them with a fluid for quick ignition.
  3. Restrictor to set for your previous place.
  4. Next, you should light the match and throw it into the furnace.
  5. Making sure that the fuel begins to gradually flared up, close the door tightly.

In the process of burning fuel will be observed a gradual shrinkage of the pipe inside the cylinder. The height of its position gives accurate information about the amount of firewood in the furnace. The scheme of the boiler on the corner is practically no different.

Testing device

The work on the construction of the boiler is most convenient to implement in the warm season right on the street. It is also recommended to test the finished design, attaching a temporary chimney to it. In cases where it is planned to give extensive premises, it is recommended to use two cylinder installed on each other to make a heater.

Montage in the house

The fire safety issue of the boiler is a very serious moment. To install it, it is better to provide a separate room or an angle, separating it with brick masonry. Since the surface of the boiler is metallic, the likelihood of burns is high when they carelessly attack it. It is also important that in place of installation it was possible to conveniently remove the chimney into the street (through the roof or wall). For free access to the device, 50 cm space around the circle is released from any items.

Installation Rules:

  • Construction of a brick basis. It should consist of two solid rows of bricks, and correspond to sizes on a solid fuel boiler for long burning.
  • The distance from the furnace door to the wall is at least 125 cm. The distance between the side parts and the wall should be at least 700 mm.
  • There is no less than 125 cm between the heat door and the wall. The space between the side of the boiler and the wall is at least 70 cm.
  • If wood used for the construction of the walls, the sections of the contact of the boiler and overlap are additionally decorated with metallic or basalt protection. The same applies to the sediments of the chimney outward through the walls or ceiling.
  • The boiler is installed on the foundation strictly by level. At the same time, the outlet should be located on one line with chimneys, otherwise violations of thrust are possible (read also: "How the thrust regulator for solid fuel boilers works - views, principle of operation, advantages").
  • All connecting nodes must be sealing sealant.
