GAS TURBINE UNIT OF GAS PUMPING UNIT WITH ANTI-ICED DEVICE Russian patent published in 2022 - IPC F02C7/47 

FIELD: power plants.

SUBSTANCE: invention relates to power plants, and more specifically to gas turbine plants of gas pumping units with anti-icing devices. The gas turbine plant of a gas compressor unit with an anti-icing device contains an air cleaning device 1 and a gas compressor unit with an axial compressor 2, a combustion chamber 3, a compressor gas turbine 4 and a supercharger 6 driven by a power gas turbine 5, which is connected to the atmosphere through an exhaust pipe 9. At the inlet of the air cleaning device 1, an injection device 12 of the anti-icing system is installed, connected by a steam pipeline 11 of superheated steam to a steam generator 10, which is located in the exhaust pipe 9 of the power gas turbine 5, and chemically purified water from the chemical water treatment 7 is supplied to the inlet of the steam generator 10 by a feed pump 8.

EFFECT: invention makes it possible to exclude the formation of ice in the air-cleaning unit and in the axial compressor of the gas turbine plant and to increase the efficiency of the gas-pumping unit.
