FIELD: power industry.
SUBSTANCE: steam-gas installation of two-circuit nuclear power plant contains a reactor 12, main steam generator 11, steam turbine with HP cylinders 1 and LP cylinders 2 connected with each other by steam line with installed separator-superheater 3, a condenser 4, electric generators 5, condensate 6 and feed 8 pumps, LP heater 7 and HP heater 9, gas turbine 15 with waste heat steam generator 17 connected at heating side to exhaust gases 16 of has turbine 15. The waste heat steam generator 17 with heating steam line 20 is connected at the heating side to main condensate bleeding pipeline 19, at that the additional heating of the feed water is performed in the steam-water heater by the intermediate steam heating medium generated in the waste heat steam generator 17 of the gas turbine 15.
EFFECT: exclusion of hydraulic and thermal losses of water and gas channels, and control inertia of steam turbine load, increasing of effective heat use of exhaust gases and gas turbine.
