FIELD: power engineering.SUBSTANCE: steam-gas plant based on a moist steam NPP comprises a steam turbine with high and low pressure cylinders connected to each other by a steam line with a separator and a live steam reheater, having pipelines of heating steam condensate, a gas turbine with a combustion chamber and a compressor, a waste heat steam generator. The waste heat steam generator is connected along the heated side to the pipelines of heating steam condensate of the live steam reheater, along the heating line - to the tract of spent gases of the gas turbine 11. Besides, the pipelines of heating steam are connected to outlets of the waste heat steam generator, at the same time the intermediate reheating of the main flow of steam is realised in the system of steam-steam reheating of the steam turbine by the intermediate steam coolant, generated in the waste heat steam generator of the gas turbine.EFFECT: invention makes it possible to eliminate significant hydraulic and thermal losses of steam and gas tracts, inertia of steam turbine load control, and also makes it possible to eliminate uncontrolled speeding in case of its emergency shutdown and sharp drop of the load in a power generator.1 dwg |
