ANTIICING SYSTEM OF GAS TRANSFER UNIT WITH GAS TURBINE DRIVE Russian patent published in 2016 - IPC F02C7/47 

FIELD: machine building.

SUBSTANCE: gas/air duct transporting the mixture of hot air and exhaust gases to the air intake channel, connected at one side with input guide vanes of the axial compressor, and from another side with air cleaning device, is equipped with the vortex pump, and motor driven control and shutdown valves controlled by valves control block by signals from atmosphere air and air intake channel transmitters, and is connected with air heater that by means of the air ducts and gas/air ducts is connected with the axial compressor, combustion chamber, gas turbine and chimney. The motor driven control valve is located in the air duct connecting the vortex pump and air duct, connecting the axial compressor and air heater, and motor driven shutdown valve is located in gas/air duct connecting the vortex pump and gas/air duct connecting the air heater and chimney.

EFFECT: increased reliability of gas transfer units with gas turbine drive by supply of the gas/air mixture at elevated temperature to the air intake channel of the axial compressor before the input guide vanes using the vortex pump.
