COMBINED UTILIZING POWER GAS TURBINE POWER PLANT OF MAIN LINE GAS PIPELINE COMPRESSOR STATION Russian patent published in 2021 - IPC F02C6/18 

FIELD: turbines or turbomachines.

SUBSTANCE: combined utilizing power gas turbine plant of compressor station of main gas pipeline includes drive gas turbine plant and a subatmospheric waste heat power plant operating on a Brayton reverse cycle. In addition, M-cycle apparatus, air-cooler-condenser, condensate discharge pipeline with pump are used in it. Device of M-cycle is installed at atmospheric air inlet to compressor of driven gas-turbine plant, containing "dry" and "wet" air channels separated by metal wall covered with hydrophilic surface water-wet. Atmospheric air is supplied into "dry" and "wet" channels. Due to evaporation of water from hydrophilic surface temperature of metal wall is lowered, in the "dry" channel the air supplied to the compressor of the gas-turbine plant is cooled. In the "wet" channel the air is cooled and moistened, then heated in the regenerative air heater, expanded in the turbine of the sub-atmospheric waste heat power plant, is cooled in air cooler due to water not evaporated from hydrophilic surface, compressed in compressor and discharged into atmosphere. Operation of turbine is used for compression of moist air in compressor and generation of electric power in electric generator. Due to the use of atmospheric energy in the M-cycle apparatus and the psychrometric temperature difference of moist and dry air, the thermal efficiency and power of the drive gas turbine plant and electric power and thermal efficiency of sub-atmosphere waste heat power plant.

EFFECT: disclosed is a combined utilizing power gas turbine plant.
