FIELD: heating.
SUBSTANCE: increase of effective efficiency of combined-cycle power plant with recovery of gas turbine spent gases heat in waste heat boiler, with water injection into stream of air that is compressed in compressor, with condensation of water steam that is contained into actuating medium of gas turbine plant in contact condenser is provided by the fact that actuating medium for gas turbine is prepared by mixing of combustion products with water steam of waste heat boiler of gas turbine and bleeding of steam from steam turbine plant in the area of combustion chamber completed burning.
EFFECT: increase of operation efficiency; provision of independence of loads of steam and gas turbines capacity and increase of combined-cycle power plant reliability and maneuverability.
