HEAT POWER COMPLEX Russian patent published in 2021 - IPC F24H3/02 

FIELD: heating systems.

SUBSTANCE: invention relates to heat supply systems of mines, mine workings and ground structures and is intended for production of heat carriers – hot air and hot water, and their supply to heating of mine ventilation air and heating of structures. Heat power complex (HPC) comprises air heating plant, having gas-air heat exchanger connected to hot air circuits, removal of flue gases (FG) and to furnace arrangement arranged with lining, which has an afterburning furnace and a combustion chamber located in front of it, equipped with a flue-type furnace with blow zones, secondary blowing nozzles connected to the blowing system and the FG circulation path, the fuel dosing unit and the slag unloading assembly. Focal chamber height is partially divided by dividing arch starting from its rear wall and connected to afterburning chamber by gas passage nozzles, which are located above the separating arch and directed tangentially relative to the vertical axis of the vortexes formed, mutually rotating in the afterburning chamber, in the lower part of the afterburning chamber there installed is a flue bin with a take-back system connected to the furnace chamber below the separation arch, and in the upper part of the afterburning chamber there are nozzles connected to the FG circulation circuit, which are also directed tangentially to vertical axes of the formed vortexes.

EFFECT: technical result is simplification and improvement of reliability of HPC elements structure at possibility of coal and coal containing wastes burning with provision of good indicators of economy and ecology.
