HEATING DEVICE Russian patent published in 2015 - IPC F24C13/00 

FIELD: heating.

SUBSTANCE: invention relates to heat exchange equipment, and namely to devices for air-and-liquid heating of rooms of different purpose at use of all types of solid fuel. A heating device includes a bell-type and a furnace chamber, the walls of which are made of fire brick along the housing outline. The furnace chamber includes a solid fuel loading door with a damper, a heat exchanger, a stack and a stack gate valve. The heat exchanger is made in the form of a water penal and installed in the middle of the bell-type chamber with a possibility of flue gas heating on all sides. Above the furnace chamber there installed is a rectangular metal plate on two transversely located angles, which together with the penal base made of a metal plate and installed on transversely located shaped rectangular metal pipes forms a flue gas combustion duct. An ash pit door is installed sideways on the rear side of the furnace chamber for the supply and control of secondary air supplied to the flue gas combustion duct. Additionally, a door with a damper is installed at the inlet of the bell-type chamber for the supply of the secondary air to the bell-type chamber and for final afterburning of the flue gas in it. In the heating device there vertically located are two rows of shaped rectangular metal pipes installed in seams of the brick masonry of the stack from a binder to the second stack gate valve with a possibility of heating the air from the hot flue gas inside the shaped rectangular metal pipes and by means of convective heat and mass exchange with a possibility of heating a room and a room that is located one floor above, where the stack is installed.

EFFECT: increasing heat and mass exchange of the heating device with air masses of a heated room or a liquid heat carrier.
