HEAT POWER COMPLEX FOR HEAT SUPPLY OF MINE WORKINGS AND PREMISES OF LARGE VOLUME AND METHOD Russian patent published in 2020 - IPC E21F3/00 F24H3/02 

FIELD: soil or rock drilling; mining.

SUBSTANCE: heat and power complex for heat supply of mine workings and premises of large volume and method relate to heat supply systems of various objects of both ground and underground purposes and are intended for production of heat energy (hot air) and supply. Proposed heat and power complex includes fuel supply system, ash-slag removal system, automated control system and air-heating plant. In its turn, air heating plant includes at least one combustion chamber with supplied to it blowing air system and secondary blowing system. Heat-and-power complex ensures production and dosed supply of hot air for heat supply of mine workings ventilation, use of heated air of furnace and secondary blowing and use of multistage cleaning of flue gases, aimed at reduction of harmful emissions into atmosphere, increases efficiency of operation and efficiency of air heating plant.

EFFECT: technical result of claimed invention in part of device and method is higher efficiency and safety of operation of complex due to new scheme of supply of blowing air and use of modified system of multistage cleaning of flue gases.
