Technical result in a heating device containing a housing with side walls, two upper walls, two lower walls formed by straight convective pipes, on top of which sheets are installed, a front wall, a rear wall and a chamber for sand, wherein the housing is made with a door installed on the front wall of the housing , air supply pipe, air supply damper, afterburning chamber, nozzle, chimney pipe with damper, gas guide lower and upper gas guide shield, firebox, protective sheet, is achieved due to the fact that two straight convective pipes are installed vertically on the rear wall.

In the closest analogue, the rear wall is exposed to high temperatures, which leads to its wear.

In the claimed utility model, the rear wall is equipped with straight convective pipes, which increases thermal conductivity, dissipates excess heat into the room, and increases the rigidity of the rear wall.

The utility model is illustrated by drawings, where

Fig. 1 - shows the heating device, front view;

Fig. 2 - shows the heating device, side view.

The heating device consists of a housing 1 with a front wall 4, a rear wall 3 and side walls 2, two upper walls 19, two lower walls 20.

Straight convective pipes 11, having a polygonal shape in the horizontal section, form the side 2, two upper walls 19, two lower walls 20 of the housing 1. The two upper walls 19 form the roof of the housing 1, the two lower walls 20 form the bottom 18 of the housing 1.

Sheets 21 are installed on top of the straight convective pipes 11, forming the side 2, two upper walls 19, and two lower walls 20 of the housing 1.

Housing 1 is made with a door 5, an air supply pipe 6, an air supply damper 7, a hatch for cleaning the afterburner chamber 8, an afterburner chamber 14, a nozzle 9, a chimney pipe 12 with a damper 16, a lower gas guide 10 and an upper gas guide shield 13, a firebox 15, a protective sheet 17.

The protective sheet 17 together with the bottom 18 of the housing 1 form a chamber for sand. On the front wall 4 of housing 1 there is a door 5 with a built-in pipe 6 and a damper 7, a hatch 8 that provides access to the afterburner chamber 14 when cleaning it from combustion products, a built-in nozzle 9 for supplying secondary air to the afterburner chamber 14.

Gas directing shields - lower 10 and upper 13 separate the furnace 15 from the afterburning chamber 14. The gas directing lower shield 10, attached to the front wall 4 of the housing 1, ensures the movement of the draft from the door 5 to the rear wall. The gas-directing upper shield 13, attached to the rear wall 3, ensures that the flue gases turn to the front wall 4 and back to the rear wall 3. Two straight convective pipes 11 are installed vertically on the rear wall 3.

The heating device operates as follows. Before starting work, sand is placed on the bottom 18 of the firebox 15, a protective sheet 17 is tightly laid on it. Door 5 located on the front wall 4 of housing 1 is opened. Kindling material is placed in the firebox 15, set on fire, door 5 is closed, and the air supply damper is fully opened. 7, located on the pipe 6 and the chimney damper 16, located on the chimney pipe 12. After the kindling material has flared up and draft has been established, firewood or another type of solid fuel is placed in the firebox 15, the door 5 is closed and the air flow is regulated by the air supply damper 7.

Under the influence of heat from fuel combustion, the walls 2, 3, 4, 19, 20 of housing 1 and straight convective pipes 11, sheets 21 outside the housing are heated, while hot air rises through the open ends in convective pipes 11, and in its place is constantly supplied cold air from below. The gas guide lower shield 10, gas guide top shield 13, protective sheet 17, and sand are also heated. The gas-directing lower shield 10 and the gas-directing upper shield 13 ensure uniform heat distribution to the housing 1 and convective pipes 11. Convective pipes 11 installed on the rear wall 3 provide heat exchange between the rear wall 3 and the surrounding air, thereby preventing it from overheating.

When the required temperature is reached in the room, the stove is smoothly switched to the “smoldering” mode, which ensures the maintenance of fuel combustion; the air supply damper 7 regulates the air flow and the damper 16 regulates the outflow of combustion products. Secondary air enters the afterburning chamber 14 through the holes in the nozzle 9.

As the fuel burns, new portions of it are added to the furnace 15. If necessary, adjust the air supply to the firebox 15 using damper 7 and the outlet of flue gases using damper 16.

The afterburning chamber 14 is periodically cleaned as follows. The hatch 8, located on the front wall 4, is removed from the body 1 and the afterburner chamber 14 is cleaned.

The use of the claimed utility model will improve the thermal conductivity and reliability of a heating device formed using convective pipes.
