    An elongate combustion chamber is inclined at a 50 DEG to 80 DEG angle to the vertical, is connected at the lower end face to a feed duct through which fuel is pushed into the chamber and is open at the upper end face. The side walls forming the lower part of the chamber are downwardly converging and the free edges are spaced from each other at a distance decreasing in the direction of the open upper end face from the lower end face to form a primary air opening from a primary air channel therebeneath, the tapered opening covered by corresponding downwardly converging solid side walls connected at an apex and spaced from the other walls to form an air passage therebetween from the primary air channel to the combustion chamber. The upper side walls of the combustion chamber defining the lower partition of a secondary air channel and being provided with openings for secondary air feed into the chamber, end plates sealing the upper and lower ends of the chamber and primary and secondary air channels, and blast-air feed conduits connected into the lower ends of the primary and secondary air channels to supply air thereto from a blower.

    The invention relates to the burning of solid fuels - in particular wood.
    Known combustion chambers of solid fuel burning contain a longitudinally inclined body connected to an air source with a coaxially positioned peripheral gap for supplying air to a combustion chamber with upper and lower open ends, one of which is connected to the fuel source, the lower half of the chamber in cross section it has the shape of a tapered To the bottom of tray 1
    However, in such furnaces it does not reach with complete smokeless combustion of solid fuel due to insufficient contact with air.
    The purpose of the invention is to improve the efficiency of combustion by improving the contact of fuel with air.
    The goal is achieved by the fact that the combustion chamber is made with a quadrangular cross-section and is provided with an additional tray with its walls parallel to the adjacent sections of the chamber and forming a slit for the passage of primary air with the latter, with the side edges of the chamber adjacent to the side walls of the chamber , its upper walls are made perforated and the lower part has longitudinal openings that increase towards the bottom of the open end communicated with the fuel source.
    Fig 1 depicts the proposed furnace, a longitudinal section; in FIG. 20, resolve AA in FIG. one.
    The combustion chamber for fuel combustion has a case 2c inclined in the longitudinal direction and connected to the air source 1 and coaxially placed with
    5 Formation of a peripheral gap 3. for air supply with a combustion chamber 4 with the upper 5 and lower 6 open ends, one of the cotoolch LODCs with a source 7 of fuel, and the lower
    0 half of the chamber has the shape of a tapering down to the bottom of the tray. Chamber 4 is made with chetyrehugolyalm cross-section and section along the periphery of the lower part is equipped with an additional tray 8,

    5 with walls parallel to the walls: adjacent portions of the chamber and forming a slit 9 for the passage of primary air with the latter; increasing towards the lower open end 6 communicated with the source 7 of the fuel. The furnace works as follows. The fuel from source 7 is pushed through the lower open end B into the combustion chamber 4. As a result, the fuel in the combustion chamber 4 is pushed forward. The air is supplied to the peripheral gap 3 in two streams: primary air to the lower part and secondary air to the upper part. The primary air is heated from the lower walls of the chamber 4 and the additional tray 8 and through the slit 9 enters the combustion chamber 4. The secondary air from the upper part of the peripheral gap through the perforations in the upper walls 12 of the chamber 4 enters the combustion chamber 4 above the fuel. Making openings 13 in the lower part of the combustion chamber 4, increasing the missus towards the lower open end, allows for a more complete contact of the primary air with the fuel, which leads to more complete combustion of the latter. Secondary air enters the chamber 4 combustion through perforations in its upper wall as 12 jets, towards. towards each other, thanks to which it twists and mixes well with the gases released from the bottom of the body, which ensures their complete combustion. Thus, in the proposed furnace, a more complete by-smoke combustion of fuel is achieved. The invention is a furnace for burning solid fuel. a housing comprising a housing inclined in the longitudinal direction and connected to the air source, coaxially arranged to form a peripheral gap for supplying the air by the combustion chamber with the upper and lower open ends. One of which is in communication with the fuel source, the lower half of the chamber in cross section. provided with an additional tray with walls parallel to the adjacent sections of the chamber and forming a slit for the passage of primary air with the latter, the lateral edges of the chamber adjacent to the side walls of the housing, its upper walls are s perforated and the lower part has longitudinal apertures which increase toward the lower open end communicated with the fuel source.
