FIELD: power engineering.
SUBSTANCE: steam-gas plant with a steam-driven gas fuel metering unit-compressor comprises a gas turbine engine with a combustion chamber and a fuel control valve, a turbogenerator, an energy steam turbine, installed on the turbogenerator shaft, a heat recovery boiler with steam circuits of one or more pressures, a gas, steam and water piping system with control and stop valves, besides, the plant also comprises a compensation turbine, installed on one shaft with a driven steam turbine and a metering unit-compressor in the common tight body at the side of the metering unit-compressor.
EFFECT: invention makes it possible to simplify development of a steam-driven metering unit-compressor and adjustment of its operation in optimal mode in wide range of loads of a gas turbine engine, as well as to increase parameters of heat efficiency of a steam-gas plant.
