FIELD: steam-turbine power plants. SUBSTANCE: coal is burned by its delivery to reactor, subjected to heat treatment to obtain combustible gas and coke/ash residue, delivery of combustible gas to burners and coke/ash residue to aero-spout furnace, and cleaning of combustion products from hard fragments; coal layer in reactor is treated, in addition, by low-temperature plasma and hard particles resulting from cleaning are evacuated. EFFECT: improved efficiency of coal combustion. 1 dwg, 1 tbl
