FIELD: heat power engineering.
SUBSTANCE: proposed steam-gas power plant contains steam turbine unit with steam boiler operating on solid fuel and steam turbine, and gas-turbine unit with gas turbine using heated compressed air as working medium, surface heater of compressed air for heating compressed air by solid fuel combustion products, and gaseous fuel combustion chamber for additional contact heating of compressed air. Surface heater of compressed air is installed in high-temperature part of convection gas pass of steam boiler.
EFFECT: increased economy of steam-gas power plant at combustion of solid fuel.
