FIELD: heat power engineering.
SUBSTANCE: according to invention, heat system of gas-turbine plant is communicated with heat system of steam-turbine plant with possibility of changing over heat flows from waste-heat boiled and steam extractions from compartment of steam turbine to optimize heat and energy loads by making waste-heat boiled with possibility of cutting off its system water heaters and delivering feed water into steam generator from condenser through waste-heat boiler. Invention provides cutting off specific capital outlays, high reliability and long service life, reduced exhaust of dangerous nitro gen oxides (NOx) to levels below tolerable ones.
EFFECT: possibility of self-contained operation of gas-turbine plant and steam-turbine plant.
