Production of solid fuel boilers long burning their hands: drawings and assembly process

Before proceeding to the self-production of boilers for solid fuels, it is necessary to prepare sketches. They are basic and additional elements should be reflected. The basis of the drawings is proposed to take a long solid combustion boiler. With their hands to make them entirely possible.

Exterior design homemade

Advantages and features of continuous burning structures

From conventional boiler supporting long analogs are distinguished by the combustion of two working chambers. The first of these is burned directly pledged fuel, and the second - the gases produced. The important role played by the timely supply of oxygen. As for the air injection can be used with a conventional fan uncomplicated automation.

Basic elements of prolonged heating combustion boiler

Of the merits of the aggregates should be noted:

  • minimum amount of fuel bookmarks;
  • high efficiency;
  • the use of different types of solid fuel;
  • a small amount of carbon black in the tubes during operation;
  • reliability of the design.

The principle of operation of a modern model

The manufacturing process of solid fuel boilers long burning their hands: and assembly drawings

Immediately should stipulate that the structures can have both upper gas combustion chamber, and a bottom. In the first case, the combustion products enter into the working compartment under the action of natural forces, while in the latter - with an additional means for air injection.

design drawings for individual processing

Since the presence of boilers afterburning chamber bottom are difficult to manufacture and require the installation of additional equipment for installation, treat them does not make sense. Faster and more economical to make a design with the upper chamber for the combustion gases.

EXAMPLE manufacturing step of homemade unit

Further, it describes how to make a long burning solid fuel boiler, using available materials.

To produce the structure required:

  • tube section 500 mm and 1300 mm in length;
  • pipe with 450 mm diameter and 1500 mm in length;
  • pipe section of 60 mm and a length of 1200 mm;
  • two rings 25 mm in width and 500 mm in diameter;
  • metal corners and pieces of sill;

Drawings of solid fuel boilers with their hands

The article describes in detail how to make drawings for Boiler slow and extremely long burning his hands. The process is only at first glance it seems a difficult and unique, but following the instructions in the article, you will have to do no worse than the masters, the main carefully watch the video.

Drawing simple continuous burning boiler

This design solid fuel boiler is quite simple. The heat exchanger can be made of sheet steel in the form of "water jacket". For maximum heat transfer efficiency and to increase the area of ​​contact with the flame and hot gases, its construction provides two reflectors (inward projections).

Drawing a simple tverdotoplevnogo boiler

With this structure, the heat exchanger is combining "water jacket" around the combustion chamber and the slot-like additional register of sheet metal in the upper part thereof.

1 - chimney; 2 - water jacket; 3 - slit exchanger; 4 - loading door; 5 - wood; 6 - lower door for igniting and cleaning; 7 - grate; 8 - door for controlling air supply and ash cleaning.

In these embodiments, the "water jacket" supplemented with heat exchange tubes of the registers at the top of the combustion chamber. In addition, these units are designed to prepare them food. 4 embodiment with greater capacity and top loading door.

This unit differs from the previous ones - firstly, the shape (circular cross section and it may be made of pipes of different diameters), and secondly, a method of burning fuel in it (it is burnt therein from top to bottom). In order to provide such a process is necessary to provide the combustion air supply from above, directly to the combustion. This function performs here telescopic air supply pipe, which rises up when loading fuel and falls down after the fuel ignition. With his gradual combustion tube under its own weight goes down. In the lower part of the tube to ensure uniform supply of air is welded "pancake" with blades.

To ensure the best combustion conditions in the upper part of the air heating chamber is located. air supply, and hence the burning rate, regulated valve at the inlet to the chamber top. The heat exchanger is designed as a "water jacket" around the combustion chamber.

Pyrolysis boiler burning solid fuel

The difference of this design is that the solid fuel is not burned in it as in the conventional, and the shortage of supply of primary air, "distilled" in the tree (pyrolysis) gas, which is burned in the afterburner chamber at a special feeding secondary air into it. Such a supply can be both natural and forced.

As mentioned feature of such boilers is the presence of two chambers: the loading chamber large vertical (shaft) and the heat exchanger chamber. Fuel is ignited from below into the first chamber through the orifice and the flame enters the other, and wherein its energy to the coolant through the heat exchanger.

Such boilers can be as with a conventional fuel combustion and pyrolysis with. In the first case, all the necessary air is supplied through the lower door, and the products of combustion passing through the heat exchanger, removed in the chimney. In the second case, the location of combustion is fed limited amount of primary air, where the wood are burned with the pyrolysis gas evolution. Moreover such designs are equipped with additional afterburning chamber, where the supplied secondary air and combustion gas is carried out. In the upper part of the heat exchange chamber located valve, which separates the ignition and allowing flue gases directly leaving the chimney.

Solid fuel boiler extremely long burning his own hands

Homemade heater will have the structure:

  1. Furnace - "box" 460 mm deep, 360 mm wide and 750 mm high with a total volume of 112 l. The volume of the fuel load to a combustion chamber of 83 liters (the entire volume can not fill the firebox) that allow the boiler to develop power to 22 - 24 kW.
  2. The bottom of the furnace - of the corner lattice, which will be stacked wood (air therethrough to enter the chamber).
  3. Under the grating should be 150 mm high compartment for collecting ash.
  4. The heat exchanger 50 liter predominantly located above the combustion chamber, but the bottom portion thereof covers with its 3 sides in a water jacket of 20 mm thick.
  5. Connected to the upper portion of the furnace flue has a vertical pipe, and horizontal flues arranged inside the heat exchanger.
  6. The firebox and ash pan closed airtight doors, and the air intake through the tube in which a fan and gravitational damper. As soon as the fan is switched off, the flap falls under its own weight, and completely covers the air intake. Once the lock sensor coolant temperature reduction to a predetermined level by the user, the controller will activate the fan for the air flow valve and opens in the furnace fire breaks out. Periodic "off" boiler in combination with bulking furnace allows to extend the work on a single load of fuel to 10 - 12 hours with wood and up to 24 hours on carbon. Well established Polish company Automatic KG Elektronik: controller with temperature sensor - model SP-05, the fan - Model DP-02.

solid fuel boiler extremely long burning his own hands

The furnace and the heat exchanger enveloped basalt wool (insulation) and placed in the housing.

The process of making the boiler with his hands.

The first step is to prepare all the necessary blanks:

  1. Steel sheet thickness of 4 - 5 mm for the manufacture furnace. Well suitable heat resistant alloyed steel grades 12H1MF or 12KhM (with additives of chromium and molybdenum) but it must boil under argon atmosphere, so need professional welder services. If you decide to make the furnace of structural steel (without alloying elements) should be used low carbon grade, such as steel 20, since the high-carbon from the extremely high temperatures can lose ductility (their hardening occurs).
  2. Sheet steel of thickness 0.3 - 0.5 mm, the colored polymer composition (decorative plating).
  3. 4-mm sheet of structural steel for the hull.
  4. DN50 pipe (flame tubes within the heat exchanger and connections for connecting the heating system).
  5. DN150 pipe (pipe for the connection of the chimney).
  6. 60x40 rectangular tube (air intake).
  7. Steel strip 20X3 mm.
  8. Stone wool 20 mm thick (density - 100 kg / cu m.).
  9. Asbestos cord for sealing openings.
  10. Handles for doors prefabricated.

Welding details should perform electrodes MR-3C or ELN-21.

Heat exchanger for solid fuel boilers with their hands

First, of the two side, one rear and one upper wall going firebox. The seams between the walls performed with full penetration (they must be sealed). Bottom to the furnace with 3 sides horizontally welded steel strip 20X3 mm, which will serve as the bottom of the water jacket.

Further, the side and rear walls of the firebox need to weld end faces at random short lengths of small diameter tubes - the so-called clip, which will provide structural rigidity of the heat exchanger.

Now to-bottom strip can be welded to the outer wall of the heat exchanger with preformed holes clips. clip length must be such that it extends slightly beyond the outer wall, to which they must be sealed weld seam.

The front and rear walls of the furnace heat exchanger are cut coaxial holes into which fire tubes are welded.

It remains to be welded to the heat exchanger tubes for connection to the circuit of the heating system.

The unit must be collected in the following order:

  1. First, the housing is made, taking short seams to its bottom sidewalls and framing the openings. Bottom ash frame opening is itself bottom of the hull.
  2. From the inside to the body of welded corners, which will be laid grill firebox pan (grate).
  3. Now you need to weld itself grille. Corners of which it is composed, it is necessary to weld the outer inclined downward, so that the air incoming from below uniformly distributed two inclined surfaces of each bracket.
  4. Next to the corners, which is stacked grate furnace welded to the heat exchanger.
  5. Firebox and ash doors are cut out from the steel sheet. Inside they are framed by steel strip stacked in two rows, between which you need to put asbestos cord.

Further welded pipe and fume collection duct with a flange for installing the fan. The duct is put into the boiler through a hole in the middle of the rear wall just below the grate.

Now you have to be welded to the boiler drum loops mates doors and several arms 20 mm wide, which will be attached paneling.

The heat exchanger is necessary to impose on three sides and on top of basalt wool, which shrinks the cord.

With screws to the brackets bolted lining.

On top of the heat generator is installed automation controller and screwed to the flange of the duct fan.

The temperature sensor should be placed under the basalt wool, so that it is in contact with the rear wall of the heat exchanger.

If desired the boiler may be equipped with a second circuit, allowing it to operate as a heater.

The contour has the form of a copper tube of about 12 mm in diameter and 10 m in length, wound within the heat exchanger flues and outputted to the outside through the back wall.

Solid fuel boiler own hands: instructions for the production of home-made heat source

The lack of a centralized gas supply makes life difficult for the homeowner: warm winter will have wood or charcoal, which constantly need to enclose.

But there is this situation is a positive side: the heat generator has a simple structure, so it's easy to make yourself.

The user not only saves a considerable amount, but also receives the unit that suits best their needs. How is a solid fuel boiler with his hands, and what ideas you can borrow from the factory model?

In general terms, the principle of operation of the boiler on the solid fuel is as follows:

  1. In a special chamber, called a furnace, placed firewood, coal or the like fuel.
  2. Loaded fuel is ignited. The process of burning in different boilers may have some characteristics, but are always the same: the reaction occurs oxidation of organic molecules, releasing large amounts of heat. The combustion rate, and thus the power of heat will depend on the amount of air entering the furnace. It can be adjusted by the movable valve mounted on the air intake (podduvalom).
  3. During the combustion heat as heat of flue gases, heats the contents of the special tank - heat exchanger. Through the inlet and outlet pipes connected to the heat exchanger and the heating circuit becomes thus part of it. Heated in a heat exchanger medium due to convection or the pump enters the heating circuit, distributing heat energy thereon.

long burning boiler - working principle

Resulting from the combustion fumes by convection is removed through a vertical pipe - the chimney.

Long burning solid fuel boiler hands - drawings, the circuit design options

There are many types of heat sources. We will focus on a few basic types:

Classic direct combustion boiler

The furnace - is just a camera, and the fuel is ignited and burns in a conventional manner, such as in a fire.

Classic boiler is easy to manufacture, but it has a major drawback: the fuel burns too quickly - every 4 hours is necessary to lay a new batch. Improve the situation in several ways:

Narrowing via air intake valve so that fuel is not burned, but slow smoldering

This option is highly irrational:

  • Oxidation of the fuel becomes incomplete, resulting in smoke contains a large amount of soot, carbon monoxide (refers to harmful emissions) and various toxic substances.
  • Due to the low temperature exhaust a large amount of condensate, the above-mentioned saturated toxins.
  • Boiler efficiency is significantly reduced.

Equipped with a heat accumulator heating system

This bulky tank in which is stored margin superheated coolant. Wood in the boiler will burn quickly, but at the same time produced no heat will fly into the pipe, but will remain in the storage tank, as it remains in the brick walls of the Russian stove. Consequently, the need to heat the boiler will be less.

Automation system to equip the boiler with forced air

The idea is the following:

  • after generating sufficient heat (temperature monitored by the coolant) Automatic completely covers the flap;
  • the flame goes out and the boiler, you can say, turn off;
  • while cooling the coolant operator opens the valve and starts the fan that blows the fire in the furnace.

Supercharged boiler

Control box with a fan you can buy in the store. The only drawback of such a decision - the dependence on electricity.

This fuel heater is placed in a column and ignited from the top. In the downward direction moves the flame is much less readily than from the bottom up, so bookmark burns longer. Moreover, to prevent the rapid spread of fire air is fed precisely into the combustion zone.

Heat generator with an upper combustion apparatus rather complicated, but there is a simplified variant available for individual processing. This so-called oven "Bubafonya", the construction of which has been developed by Athanasius Bubyakin.

The problem is that the presence of the water jacket characteristics of this unit is strongly fall (very low efficiency, smokes heavily furnace), so its use as boiler irrationally.

Gasification (pyrolysis) boiler

Exposed to high temperature fuel organic molecules (biopolymers) partially decompose into various gaseous species (wood gas), many of which can burn. Such a decay is called pyrolysis. In normal combustion of the mixture gas is ejected mainly in the chimney. The gasification boiler is diverted into a separate chamber (afterburning chamber), where it is combusted.

Such a boiler has a number of advantages (high efficiency, long work on one tab, and so forth.), But it is complicated to manufacture, requires the use of special catalysts and needs a forced air supply.

Scheme gasification boiler

It is possible to produce a simplified version of the type furnaces "Professor Butakov», «Breneran» and «Bullerjan», which have a similarity afterburning chamber in the upper part of the furnace.

But such units are, firstly, are designed to operate in the smoldering mode, the shortcomings of which we have spoken above, and secondly, as "Bubafonya" loses much of its characteristics in the selection of the heat of the water, that is, when used as a boiler.

Thus, the most suitable for independent production is a classic boiler which in the presence of electricity in the house can be equipped with automatic blow-in fan.

Gas boilers Baxi with automatic gain in our country often. Reliability and price - the main components of the success of the consumer. Baxi boiler - instructions for use and the device unit.
