Solid fuel boilers of long burning helps maintain heat without frequent cutting of firewood.
Instead of ordinary 2-4 hours, one bookmark In the boilers of long burning, there is enough at least on 8-12 hours Equipment work. The exact time between loads depends on the design and type of fuel used.
Long operation of the device with the heat exchanger on one batch of firewood Provides special design:
Fire covers the top layer of fuel. Deduced by the dosage flow of the air flow is formed smooth, mesmer flame. Lower bookmarks are gradually heated as firewood is improved.
In standard drawings install thermal cylinder generator. The rectangular body for classic long burning boilers does not fit.
The equipment works as follows:
In addition to firewood, peat or coke is used.
Photo 1. Classic solid fuel boiler for long burning with firewood in a fire chamber and a lack of heat exchanger.
In gas generator devices firewood is smolder slower. Fuel smoke is allocated, which enters a separate zone and produces additional thermal energy. The design includes:
Two cameras Parts fire-resistant overlap with nozzle and holes. From the secondary air flow depends the heating rate inside the heat exchanger.
Photo 2. Pyrolysis boiler equipped with a loading chamber, heat exchanger, chambers are separated by fire-resistant overlap.
Devices working on the principle of conventional fuel combustion, Easier pyrolysis. The design includes:
After loading and ignition, fuel highlights combustible gases. Through the hole they enter the chamber with the heat exchanger, heating the latter. Smoke gives energy and comes out through the pipe, and hot water enters the heating network.
Photo 3. Cable for long combustion of mine type with a heat exchanger in which the fuel highlights combustible gases after ignition.
To choose the right design, recommend to take into account the area of \u200b\u200bthe room and the type of fuel. If the boiler build for a garage or cottage house of a small square, in the water circuit there is no need. Heating comes from the surface of the device due to hot air convection.
Attention! To increase efficiency and efficiency, the device is complemented environmental blowing system with fan. If there is a heating network with a liquid heat carrier in the room, projects with a contour are chosen in the form of a "coil" based on pipes.
The type of fuel affects the volume of the chamber. For woodcuts Boilers are suitable projects with enlarged furnaces. When using pellets or chips, it is possible to arrange a container for automatic granules.
Easier to build a design based on metal with brick. To do this, they make a heat exchanger from profile pipes of round and rectangular cross section, which is installed directly into the brick boiler.

To reduce costs, choose products from alloy steel 20 brands.
When building a heat exchanger and boiler use:
For the assembly of the heating device of long burning suitable electrodes MR-3C or ANO-21.
Heat exchanger with their own hands of 4 pipes 60x40 mm, round blanks D40 and D50 mm. Optimal wall thickness - 3-5 mm. From rectangular pipes long 300 mm Make vertical racks - 2. Front and rear of the register. For this:
Important! Rightness on the surface of the pipes necessarily remove Bulgarian for accurate welding.
To prepare a connection racks, follow these steps:
Front vertical racks connect with rear 8 long (800x50 mm) Round pipes. They are exhibited perpendicular to each other and weld. Between the rear racks spend 4 short (300x40 mm) round pipes . From the bottom of the front racks install long (500x50 mm) rectangular pipe With a feeding hole.
Important! All faces are located strictly perpendicular to each other. The welding is performed on an even base to avoid the distortion. It is better to connect racks and pipes with an assistant.
When the heat exchanger frame is ready, short segments ( 100-150x50 mm) We weld to the places of connection to the heating network, and all open ends of the racks are closed with metal sections.
To checkheat Exchanger on impenetrable Before installation, the bottom hole is closed, and the container is filled with water through the top.
Design is located in a vertical position. In the absence of leaks, the heat exchanger is ready for installation.
Before creating a brick case building concrete foundation Taking into account the size of the device. It is laying out the confusion chamber, the grate is mounted. The heat exchanger is installed with the inclination towards the flow of cold water.
The output nozzle must be located above any top of the design. Minimum difference in height - from 10 mm or more. This eliminates the risk of aircraft formation, improves water circulation.
Attention! Between the brick surface and the extreme part of the heat exchanger, be sure to leave the gap minimum 10 mm.
The finished design with a pipe is plated with fire-resistant or chammatory brick. The optimal thickness of the walls of the fuel ½ block.
Leave the openings in advance and install 2 doors:
The latter is installed on the lid or front wall of the device. The bottom door is optionally replaced by two separate smaller size.
Masonry produce with mandatory dressing of seams. The outer brick case is erected above the pipes minimum by 20-30 mm. The top is closed with a cast-iron sheet for quick dismantling if necessary. In designs are used smoky pipe Metal or brick residues. It is installed on the height from 5 or more meters relative to the level of the grate.
The finished device is designed to work in the offline network. with the natural and compulsory circulation circulation of the energy carrier. In the first case, the following steps:
All locations of the compounds must be wrapped up and covered sealant.
Equipment is installed only on the concrete base. Steel rental does not withstand weight and boiler sacks. This leads to loss of density of compounds and damage to pipes.
Use homemade door For fireboxes and ash splices are not recommended. The slightest irregularities Reduce the efficiency of burning firewood.
Moreover, perhaps deposition of coal Through the gaps with subsequent fire. With independent manufacture of the door, it is strictly under the hole, provide dampers and thermal insulation between the layers.
If the heat exchanger boiler is used in the local heating network, circulation pump Install on the return. So the device works in gentle mode for 6 or more. To solve the problem of low-temperature corrosion on the bypass (jumper), you set a three-way thermostatic valve and adjust by 55 degrees.
The resistant smell of creosote and smoke in the boiler room speak of low fuel quality. Cheap wooden sleepers are not suitable for heating and form evil coal residues on the walls less than per day burning. To eliminate heat loss through the chimney, the latter is equipped damper. It prevents the outlet of heated air, reduces the fuel burning rate.
The video presents one of the schemes for creating a solid fuel boiler with minimal cost.
The basic welding skills are enough to build a long-burning boiler with a heat exchanger without assistance.
Detailed instructions helps to assemble a device with a heat exchanger for heating at home an area of \u200b\u200bup to 100 m2 with six 7-section radiators made of cast iron and wiring with 2 pipes.
In accordance with SNiP, before the first launch of the boiler perform 24-hour hydraulic check. For this:
A simple method helps make sure that there are no leaks. Be sure to check the sections of the threaded connection and welds. The pressure level should be saved unchanged. When any problems are detected, the boiler is disconnected from the heating network and eliminate problems.

An interesting fact: Among the variety of solid fuel boilers coming on sale, it is not easy to choose an aggregate that can work on firewood or angle at least 6 hours and at the same time to highlight the required amount of heat. The sellers of heating technology declare and more, but their words are rarely true. Hence the conclusion: if you can buy the desired product, either too expensive, then nothing remains, except to make the boiler for long burning with your own hands. Do you own welding and want to start making? Then this article is for you.
Before considering different options for wood and coal heating units, we propose to clarify the question of where the duration of burning is taken as such. Thanks to the efforts of sellers and advertisers, most users have an opinion that it contributes to the smoldering of the boiler operation, in which the wood is burned very slowly.
In real life, you cannot constantly exploit the heat generator in the mode of radiation and that's why:
In fact, sales representatives are shy or they themselves do not understand what they are talking about. Real solid fuel boilers for long burning are equipped with an increased volume. The more firewood is placed in it, the longer they burn and efficiently give warmly. Specifically, this is expressed in the numbers: the volume of the furnace of a conventional unit with a capacity of 20-22 kW does not exceed 65 liters, and the time of operation is 6 hours. Our goal is to make a long-burning heat generator with an 80-100 liters, which is not working with 1 wood laying. less than 7-8 hours, and coal - up to 1 day.
ATMOS C 20S (left) and Viessmann Vitoligno 100-S VL1A024 (Right)
Reference. Let us give a few examples of factory manufacturer boilers that meet this requirement (shown above in the photo). This is a Viessmann Vitoligno 100-S VL1A024-25 kW (100 L), Atmos C 20S (20 kW - 100 liters) and, of course, stropuva with a giant camera is 260 liters (this is the secret of long burning). This also includes modern aggregates on pellet, whose fuel supply in the bunker allows you to continuously provide heating to 7 days.
Now list the popular types of homemade boilers:
About how to make a pyrolysis heat generator with your own hands, we were previously told, so we will not be reused. As for the mine boiler shown in the diagram, its assembly and operation is associated with some difficulties. The product is quite cumbersome and material, in addition, too large tubular heat exchanger is quickly clogged with soot when using wet wood.
Design of a mine heater in the context
You ask - why with compulsory upgrade? It is necessary to avoid the notorious mode and economically burn solid fuel. The principle of action is as follows:
Note. The inexpensive automation kit shown in the photo involved in this boiler allows you to organize air injection in several intensity modes for wood and coal of different quality and humidity.
Presented below in the drawing, a solid fuel boiler for long combustion of the universal type of coal / firewood has the following technical parameters, proven in practice:
The device of the wood heat generator is quite simple: the furnace stretched into the height is equipped with sandbresses, and from above - a heat exchanger of 4 pipes placed inside the tank.
Air injection is performed in the ash chamber along the channel from the profile of 60 x 40 mm, heated by the rear wall of the fuel. The fan and the automation unit are installed on top, which protects them from dust and dirt. All the details of the design are shown in the drawings that you can take the basis for self-making.
Homemade water boilers Long burning, where the burning of fuel is organized from top to bottom, are made by the type of a widely known oven bunch, whose we gave earlier. The heat generator is the same stove, only equipped with a water jacket, as demonstrated in the drawing.
Working diagram with top burning wooden chocks
Important moment. The principle of the heater is considered relatively new and lies in the fact that the air to the fuel array is supplied from above, along a pipe with a heavy metal disc at the end. The burning zone is also located at the top, and the firewood as burning is seated under the weight of the cargo. As a rule, the air flow moves naturally due to the thrust of the chimney, although, if desired, you can organize a forced feed.
Judging by the reviews of real users on thematic forums, similar boilers on solid fuel for long burning are not very well proven. There are several reasons:
More interesting features Cylindrical design boilers will reveal the heating expert in his video:
Building a reliable TT-boiler capable of listening to more than 15 years, requires the use of such materials:
Council. It is not necessary to use high carbon steel on the fuel tip above ST20. Firstly, it is more expensive at the price, and secondly, it turns out of welding and can crack on the joints. Handles for doors with ebonite overlays are better to buy ready, they are tightly kept and looks more beautiful.
Of the additional materials you will need a basalt fiber with a density of 80-100 kg / m³ for thermal insulation of the case and asbestos-graphite cord on the seal of the door-facing. A set of automation and fan, which was mentioned in the previous section - Polish production, model KG Elektronik SP-05. There are Chinese analogs on the market, they are cheaper.
To cook the fuel chamber, you must cut the metal of 4 mm on the billet in size specified in the drawing. Collect Start from the bottom of the ash bar - grab the side walls and the lid to it, and then form the framing for the boot and the clean door, as is done in the photo.
Note, heat pipes converge in a bunch of chimney nozzle
Council. If you have conceived to make a dual-circuit boiler for long burning, then the water coil for the DHW is put at this stage. The best place For a heat exchanger from a copper or stainless tube - inside the upper boiler tank, next to iron pipes.
The doors of the fuel and ash chamber are made by flexing the edges of the billets and welding the internal frame where the basalt insulation is stacked. From above, insulation is hermetically closed with a lid, and an asbestos-graphite cord is tightly inserted into the resulting groove on the perimeter.
What else to do:
To insulate and bind a homemade TT-boiler, on the corners of the water shirt, it is necessary to spend the mortgage parts from any metal, if only its width exceeds 20 mm (on the rear wall - 4 cm). Also pride the racks for attaching the computer on the top of the unit.
The heat insulation of the boiler tank is simply performed - the walls are placed outside basalt wool slabs, which are fixed with the cord. Make sure the insulation tightly lightened to the frame of the boot and ash opening, as well as to the profile pipe of the air duct.
Council. Before insulation and facing, a temperature sensor from the automatic block is required to be mounted in the case. The standard solution is the installation of the submersible sleeve, but it can be done easier to put it between the insulation and the shirt wall in the hottest place - in the area of \u200b\u200bthe furnace.
So mounted control unit and fan
The last step is the sheathing of the heat generator with a metal with polymer painting, screwed screws to previously welded mortgages. After that, the doors are hung and the automation unit is installed with a fan. To understand the assembly process will help you with the author's video from the developer of this TT-boiler of prolonged burning Vitaly Dashko:
In fact, the Internet has already published a huge number of instructions for the manufacture of such heating units, since it is for some reason they are considered to be long-burning boilers. True, none of them says how homemade Master Make a round case and water shirt without roller machine. The rectangular shape of the furnace will not fit - in the corners of the wood will be burned worse and "hang" on the walls.
Note. Old gas cylinder From under the propane used for the manufacture of bubfoni, it is not suitable for the boiler - too small volume (only 50 liters). With such a camera, the heat generator of super grade you will not get. Need steel pipe With a wall thickness of 4 mm and an outer diameter of at least 40 cm.
The simplest solution is to docile 2 gas cylinders and make a primitive shirt
It will take from the materials:
How can I wear a shirt on a cylindrical furnace
On the insulation of the case, take the same basalt wool of a large density and painted metal - on the facing. It remains to solve the main question - how at home to bend metal under cylindrical furnace to make a water shirt. Output options from the situation are reflected in the diagram - if there are no rollers nearby, the casing is performed from the segments in the form of a polyhedron or simply square section.
Council. Perhaps you will be able to find the pipe of the larger diameter and put it on the fifthly, but then the weight of the heater will be quite impressive, and he will warm up.
The assembly of the TT-boiler of prolonged upper combustion is made like this:
This assembly process is over. So that the unit looked attractive, paint all the unimposed elements in black or other dark color And go to tests.
If you managed to cope with the independent manufacture of a "long-playing" boiler, the next step is to check and operate it. Since homemade craftsmen do not always have a compressor for pneumatic tests, the best way - Put the heater in the yard, fill in water and ignite, bringing 90 ° C to the operating temperature. Lovely joints will be known about themselves, just need to withstand at least 1 hour in this mode. For heat leading, come up with some radiator or register from pipes.

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 lack of them are often refused when arranged heating system, 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 (exceptionally solid, of course).
The scheme of operation of such boilers is based on the features to smooth several hours, while 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.
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.
Allocated on the background of heating systems of other types. Of course, the main advantage is the duration of work, but there are other important points:
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 \u200b\u200bthe room.
Regardless of the modification, the boiler consists of three main zones:
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.
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.
Air can be served one of two ways:
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.
Method number 1. A serpentine is connected to the heat exchanger tube passing through the combustion zone, which is connected by the coil, through which water is heated in the tank.
Method number 2. A separate metal tank is formed, through which the chimney pipe is passed. Heated smoke warms the liquid.
The first method is more efficient, but at the same time complicated in performance. The second to do is easier, but it is advisable only in small houses.
Solid fuel boilers
Make such a design at home is easy, but for this you will need skills and clear instructions.
For the manufacture of the boiler will be required:
After training equipment and supplies You can proceed to work.
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 housing is clipped 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.
Step 2. The air distributor is formed. For this, the circle is cut out of the sheet, the diameter of which is less than the diameter of the design by 2 cm. In the center of the circle, the hole Ø2 cm is done.
The impeller is welded to the distributor with 5-centimeter blades fixed on it made from the same steel. The pipe Ø6 cm pipe is welding from above in such a way that in the middle fell earlier hole.
Note! This pipe should be equal to the height of the boiler housing (can be more).
From above, the pipe is equipped with a flap for adjusting the oxygen supply.
Step 3. Near the bottom of the boiler is equipped with a door to remove combustion products. The grinding from the steel sheet is cut out the rectangle, the loops with a shut-off handle are fixed. Rectangle and serve as a door.
Step 4. From above on the boiler, the chimney tube Ø10 cm is attached. The first 40-45 cm pipe should go strictly horizontally, after which it is passed through the heat exchanger (the latter is performed as a metal tank).
Step 5. The cover for the boiler is cut, it is done in it for a air distributor. It is important that the cover adjacent to the housing is as tight as possible, otherwise the smoke will go through the slots.
All, long burning heat generator is ready to use.
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.
Note! Not only firewood can be used as fuel, but also sawdust, coal, peat, garbage (extremely combed) and so on.
Fuel is loaded into such a sequence.
Step 1. The upper cover of the design is removed.
Step 2. Air regulator is extracted.
Step 3. The boiler is loaded with fuel at the level of the chimney pipe.
Step 4. From above, the fuel is poured by a small amount of fluid for ignition (diesel oil, and solar oolars.).
Step 5. The air regulator is installed back, the cover is put on top.
Step 6. The air damper opens to the limit.
Step 7. The piece of paper is mounted, 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 sinking along with air regulator - On this peculiar indicator and you can determine the amount of the remaining fuel.
The boilers described are used not only for, but also winter heating Hellev, Sarai, 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 original combustion chamber provides an increase in the heat carrier heating area. The built-in circuit for cooling does not give the heat carrier to warm over 110 degrees.
Solid fuel boiler Protherm Beaver 40 DloOf the modern combustible materials in everyday life, solid fuel is considered. This category includes coal, firewood, peat, briquettes or pellets. Traditional ovens provide cheap and simple heating of houses. However, constant fuel boot is necessary. This method of work presents difficulties in the heating of the whole home. An excellent solution to the problem is a boiler for long burning with water contour.
For installation and operation, no resolution of the supervisory structures is required. Therefore, the heating unit is easy to make and mounted with your own hands. For this, you will need minimal financial costs, boiler drawings and detailed instructions on making.
Principle of operation
The aggregates are an improved type of solid fuel furnaces. Powerful boilers are able to effectively heat not only residential buildings, but also production, auxiliary and commercial premises. The water circuit boiler technology is built on a slow fuel combustion with a high degree of heat transfer. The boiler is a bulk furnace with a limited ignition area. Firewood or pellets are laying every 12-18 hours. Adjusting the air flow, served from above, intensive burning is transferred to slow drainage.
Exhaust gases are removed through a chimney pipe. It passes through the heat exchanger and heats the water for the heating system. Thus, the loading of fuel is made with a rare frequency, and the system functions almost in continuous mode.
Heating aggregates on firewood are an excellent alternative gas devices. They are characterized by multiple advantages:
1. High efficiency - due to the slow combustion of fuel, the efficiency reaches 90%.
2. Long activity - bulk firebox with a powerful injection fan is able to ensure continuous operation of up to 7 days.
3. Environmental friendliness - when combustion of organic fuel, an insignificant amount of carbon dioxide is released into the atmosphere.
4. Efficiency - Built-in electronics helps to configure the optimal boiler loading mode.
Heating aggregates of slow burning are presented in the modern market in three species.
Work on the corner, firewood or woody briquettes. Thanks to a small firebox, the combustion period of one bookmark is reduced. To ensure continuous functioning during the day, the fuel has to be filled with 4-6 times. The advantage of classic boilers is considered low price.
Design with a bulk bunker and a wide bootable opening. Dry bulk materials are used. Automatic control optimizes the combustion process. Depending on the download, the powerful boiler is running from 6 to 24 hours. The efficiency is no more than 75%.
Function on the principle of burning wood gases allocated in the process of slow radiance. The design provides high heat transfer efficiency and fast heat carrier heating. On one boot, the furnace works until the fuel is completely burndown, the KDP is 85%.
Scheme wood stove With water contour
Boilers according to the drawings of Vasily Emptychenko - these are simple and affordable installations that can be made with your own hands. The base is used by a semi-welded pipe, a steel barrel or a used gas cylinder. The thickness of the metal walls should be at least 3-4 mm. This reduces the burnout of the metal and provides long-term uninterrupted equipment. The height of the base varies from 800 to 1000 mm. From the value of this parameter, the volume of one-time loading of fuel depends.
The diagram of the heating boiler on firewood consists of three parts:
The flue chamber limits the air distributor. This is a metal circle with a thickness of 4-6 mm with a hole in the center. The telescopic (or one-piece) pipe supplying oxygen into the combustion zone passes through it. The dispenser disk is in motion, so its diameter is slightly less than the boiler body. In the injection pipe, the air falls out of the atmosphere, penetrating through the top valve.
Exhaust gases are removed through the chimney, fixed in the upper part. Below on the wall there is a door through which the ashes and ashes are removed. In durable burning boilers, solid fuel is burned almost completely, so waste is deleted infrequently. In addition, the design includes points to connect the supply and reverse water removal. Also define the location of the thermometer and the thrust regulator.
To warm the coolant in the water circuit in two ways:
1. Make a remote cumulative tank, inside which skip the pipe. Exhaust gases are moving along the chimney and simultaneously heat the water.
2. Skip the heat exchanger pipe through the combustion chamber. Connect a coil to it, which is located in a cumulative tank.
The effectiveness of the second method is higher. However, the technology of execution looks much more difficult.
If there is not enough money to buy a finished heating device, you can try to make it yourself. First you have to explore the drawings, familiarize yourself with the instructions and calculate possible costs.
To create a boiler, you will need materials and devices:
In accordance with the drawings, it is necessary to make a single case, chimney, air distributor, door and cover for the top.
Step-by-step instruction:
1. Crop the pipe with a grinder so that its length is about meter. How to level the edges. On the one hand, brew a round bottom, carved from the steel sheet. You can immediately attach the reinforcement legs.
2. Make an air distributor:
3. At the bottom of the housing, the grinder is cut out a square opening, through which it is convenient to clean the ash. Then the loops weld and hang the door with the valve.
4. In the top of the casing closer to the edge, a circular hole is cut. It is welded with a coupling with threads, on which the chimney pipe of the æ100-150 is fixed. A plot of up to 500 mm long should be strictly horizontally. Then the pipe passes through the heat exchanger, made in the form of a storage tank.
5. From sheet metal you need to make a cover with a hole in the middle. Through it will pass the tube of the distributor. So that the cover fits tightly to the combustion chamber and did not let the smoke, the seal from the asbestos cord is paved along the cutting diameter.
Since the equipment does not work on gas, but on firewood, its installation can also be carried out independently.
1. All long-burning boilers made by their own hands have a large mass. When loading firewood, the design becomes much harder. Therefore, under it you need a strong and even foundation. In the Installation Guide, it is recommended to fill with reinforced concrete with an admixture of rubbank or boot. Alternatively, you can lay out the base of the brick.
2. The outer walls of the case in the combustion chamber zone are strongly heated. Even if a water jacket is located around the furnace, it does not protect the surfaces from overheating. As a rule, all homemade long-burning boilers have a single casing. Therefore, the minimum distance to the nearest wall should be 50 cm.
3. If the room is decorated with combustible materials, a protective surface of galvanized sheets with a gasket from asbestos should be built. You can also fold brickwork.
4. The space of 25-30 cm wide between the overlap and the chimney pipe is filled stone Vata. And we are sewn with an asbestos layer. All these actions significantly increase the total costs of a long-burning boiler, but guarantee fire safety.
The manufacture of a solid fuel boiler with their own hands is a complex and responsible event that requires careful preparation. It is necessary to know the production technology, to own the skills of welding and working with metals. Following the main rules for the development of boilers, you will create the heating device quickly and with minimal costs.
General view of the boiler
A solid fuel boiler for long burning is a large furnace having a limited burning zone of solid fuel combustion and controlled oxygen flow. The principle of operation of the device is based on the ability of solid fuel elements to smooth for a long time with increased heat transfer. In the process, there is a complete extension of the substance with minimal waste generation.
Loading a large amount of solid fuel in the furnace takes place on average 1-2 times a day, but there are aggregates that can function within a few days. By regulating the inflow of oxygen into the combustion zone, slowed down at elevated temperature. Smoke is output through a special pipe. It passes through the heat exchanger and warms the water for the heating system. Timely loading of the furnace provides almost continuous operation of the device.
Fuel combustion in a long-burning boiler is more often going down. In this case, as the upper layer is extended, the fire moves below, to the following layers. Such thermal units have many advantages that ensure their popularity among all groups of the population:
Standard long combustion boilers differ from the type of fuel used:
By type of work, all existing types of long-term combustion boilers can be divided into two large groups:
The area of \u200b\u200busing solid fuel boilers is extensive. Household models are heated private households, shops and similar residential and non-residential facilities. Large industrial aggregates, for the placement of which a separate equipped room is required, a small plant can be pulled out. The popularity of boilers is due to small cost and ease of operation.
Main nodes heating device
In short, the essence of the work and the device of a solid fuel pyrolysis of long-burning boiler can be reduced to the following:
A simple boiler can be done with your own hands.
For the manufacture of a boiler running on solid fuelIt is necessary to develop a drawing or scheme. It displays approximate appearance Aggregate in compliance with all proportions, parts and elements.
All nodes and details of the industrial boiler are indicated.
We will understand more about the creation of a pyrolysis boiler of long burning with their own hands. It functions on gas obtained from dried firewood or covered in waste pallets.
In the process of independent manufacture of a solid fuel boiler, a set of power tools and materials will be required, as well as a drawing or diagram with a display of all the desired parts and sizes.
Needed technique:
The process of creating a heating device is quite simple and passes in several consecutive steps.
Initially, the construction case is manufactured:
The door of the ashbar cuts up below
The size should be sufficient to bookmarker
The pipe is welded to the pipe for the withdrawal of smoke
After creating a metal body of a solid fuel boiler, you can start making and installing the air distributor:
The air distributor can be performed in the form of a pancake with welded chapels
This is one of the simplest ways to manufacture a solid fuel boiler. There are complicated schemes used in industrial and household models.
The manufacture of a pyrolysis solid fuel boiler of long burning occurs according to a similar pattern: the welding of the case, the air distributor, the installation of accessories, etc. The main difference from the classic device is the presence of two cameras. The first fuel burns, pyrolysis gases are burned. For such a boiler, it is very important to provide a constant inflow of oxygen.This can be done with the fan.
Solid fuel pyrolysis boilers with a lower combustion chamber differ according to the features of the design and combustion of fuel.
Pyrolysis units with an upper chamber are considered more productive. They provide slow and uniform burning fuel. Some industrial wood boilers can work for about two days. When bookmarking the same portion of coal, the term of work increases to the week.
To install the heating system, a specially equipped place may be required. In the residential premises, it is not recommended to put such a design: the danger of fires, leaks increases. Relevant services can impose a fine. Very often, homemade units are installed in greenhouses, technical and work premises.
When installing a solid fuel boiler, it should be guided by some requirements:
After assembling and installing a solid fuel boiler, you must make a test load called accelerating furnace. Load fuel for the first time it follows before the start of the heating season. In the event of troubleshooting, there will be some time before bringing the system to proper condition.
A solid fuel boiler can work almost on any fuel. For acceleration firebox, use the type of fuel that is planned for constant loading. The furnace is filled in completely, to the outlet tube. So that the fuel is better roasted, you can sprinkle a little standard fluid for ignition.
The boiler is lit with a long chip or lady, through the open damper. Until the loaded fuel was started, the damper cannot be closed. Then you can cover it. If the combustion rates are not enough to optimally work the heating device, the flap is opened to improve the thrust. With the first furnace, the loaded hard fuel should be completely ruined. It is possible to find out the smoke that appeared from the chimney. In the process of combustion of individual fuel layers, the air distributor pipe will be descended, it can also be determined by the rate of tension.
An independent manufacture of a long-burning boiler is a reality that is available to each, regardless of whether you are in its manufacture or not. The main thing is not to forget about fire safety: After all, each heating device is a potentially dangerous device.
