FIELD: power industry.
SUBSTANCE: combined-cycle plant with a steam-turbine drive of a compressor and a high-pressure steam generator, which includes a compressor, a high-pressure steam generator, a gas turbine, a heat recovery steam generator, a vacuum deaerator, a condensing steam turbine, a back-pressure steam turbine and an electric generator.
EFFECT: invention allows increasing a value of the ratio of steam consumption to gas consumption, increasing steam-generating capacity, reducing metal consumption of heat exchange surfaces, increasing electrical capacity, reducing gas temperature in the internal housing of a double-housing part of the high-pressure steam generator, as well as reducing formation of nitrogen dioxide in combustion products.
