The technical result is ensured by the fact that the solid fuel boiler includes a housing, a water jacket made around the entire perimeter of the boiler, a furnace chamber, a chamber for exhausting flue gases into the chimney, primary air supply means, secondary air supply means, a grate, first water inlet and outlet pipes a circuit including a water jacket, a heat exchanger containing two packets of horizontal pipes. The heat exchanger tubes are placed in the chamber for exhaust gas discharge into the chimney across the movement of the exhaust gases and provide the possibility of turbulization of the exhaust gas flow and additional heat removal. In addition, the boiler further comprises an exhaust gas afterburner formed by horizontal walls separating the afterburner from the combustion chamber and the exhaust chamber to the flue, and having a fireclay wiring. At the same time, secondary air injectors are located in the afterburner, connected to the secondary air supply tunnel, made at the rear wall of the furnace chamber and providing the possibility of supplying secondary air from bottom to top through the furnace chamber. Tunnel-catalysts made of fireclay bricks are made in the afterburner. The solid fuel boiler further comprises secondary water inlet and outlet pipes, including a heat exchanger. At least part of the furnace chamber inside is made with chamotte lining.

In accordance with a particular case of execution, the device has the following features.

The surface of the water jacket is made developed by means of recesses formed by means of a stamp and provided with an electric rivet.

The essence of this utility model is illustrated by the illustration, which shows an isometric image of the device.

The following structural elements are displayed in the illustration:

1 - the chamber door of the furnace;

2 - a door of adjustment of supply of primary air;

3 - pipe outlet water;

4 - the door of the technological window;

5 - window for secondary air intake;

6 - water shirt;

7 - chamber for afterburning of exhaust gases;

8 - catalyst tunnels;

9 - a chamber for discharging flue gases into the chimney;

10 - heat exchanger pipes;

11 - the chamber of the furnace;

12 - chamotte lining;

13 - injector.

The solid fuel boiler includes a housing, in front of which a furnace door 1 and a primary air supply adjustment door 2 are made (a window through which air enters is a primary air supply means). Water for heating enters through the inlet pipe and exits through the pipe 3. These pipes are pipes of the first circuit, including a water jacket 6, made around the entire perimeter of the boiler. The surface of the water jacket 6 can be made developed by means of recesses formed by means of a stamp and provided with an electric rivet. This increases its rigidity and increases the safety and life of the device.

In the upper part, the housing is connected to a chimney equipped with a gate with a damper regulator. In addition, a technological window is provided in the front of the casing, equipped with a door 4. In the lower part of the casing there is a window with a hinged lid for intake of secondary air 5. The boiler contains several chambers: an afterburning chamber for flue gases 7 made with chamotte lining and with tunnels made of catalysts fireclay brick 8 and located between the chamber for removal of exhaust gases 9 into the chimney and the furnace chamber 11, including the grate, the grate shelf, the chamber floor and the chamotte lining 12, made on the top of the chamber and 11, on at least part of its walls.

The exhaust gas afterburner chamber 7 is formed by horizontal walls separating the afterburner chamber 7 from the furnace chamber 11 and the exhaust gas chamber into the chimney 9. Moreover, there is a labyrinth in the afterburner chamber 7 including tunnels-catalysts made of fireclay brick 8 and the secondary air injector 13 connected to the secondary air supply tunnels made at the rear wall of the furnace chamber 11 and providing the possibility of supplying secondary air from the bottom-up from the secondary air intake window 5 and through the entire furnace chamber 11.

A heat exchanger is provided in the chamber for discharging exhaust gas 9 into the chimney 9, containing two packages of horizontal pipes 10, which are placed in the chamber for discharging exhaust gas 9 into the chimney across the movement of the exhaust gases (at different angles) and allow the turbulence of the exhaust gas flow. At the same time, the pipes 10 are washed along the entire length with exhaust gases to ensure heat removal and heating of the water. In addition, the coupling of the electric heating element is integrated in the heat exchanger.

The boiler also has secondary water inlet and outlet pipes, including a heat exchanger.

The boiler provides water for heating the room from the first circuit, and hot water for water supply from the second circuit.

The boiler operates as follows.

For long-burning boilers with flue gas afterburning, the main type of fuel is firewood or sawdust briquettes, coal can also be used as an alternative fuel.

Open the door of the furnace 1, lay paper or wood chips for ignition. Install the primary air supply adjustment door 2 at an angle of 45 °, open the gate (using the damper control) in the chimney exhaust pipe completely to ensure maximum traction.

They set fire to wood chips or paper, report a few small firewood to the resulting fire, close the firebox door 1. Then lay 1/3 of the firebox chamber with firewood.

Five to seven minutes later, completely lay the firewood in the firebox.

After that, the primary air supply adjustment door 2 must be half closed so that smoke does not escape through the air gap. After the air in the heated room heats up, close the door for adjusting the air supply 2, leaving an air gap of about 3-5 mm. Then close half the gate in the flue pipe.

Thus, the correct operation of the boiler will be ensured and, accordingly, the most efficient and sufficiently long operating mode. The mode of operation of the boiler is also economical, since in the chamber 7 is the afterburning of exhaust gases. The secondary air entering the chamber 7 does not lower the temperature, since the secondary air supply tunnels are made at the rear wall of the furnace chamber 11 and provide secondary air supply from the bottom up. The execution of tunnels at the rear wall of the chamber of the furnace 11 is due to the fact that it is more intense heating that takes place in it. In addition, the device effectively uses the heat of the exhaust gases, which also heat up the chamotte lining of the device. The afterburning chamber 7 is made with a labyrinth of fireclay bricks including catalyst tunnels 8, which provide ignition and stabilization of combustion and afterburning of pyrolysis gases during the transition of the boiler to pyrolysis or afterburning without primary air. A heat exchanger is provided in the chamber for discharging exhaust gas 9 into the chimney 9, containing two packages of horizontal pipes 10, which are placed in the chamber for discharging exhaust gas 9 into the chimney across the movement of the exhaust gases (at different angles) and allow the turbulence of the exhaust gas flow. At the same time, pipes along the entire length are washed by exhaust gases to ensure heat removal and water heating.
