GAS TRANSFER UNIT Russian patent published in 2020 - IPC F04D25/02 

FIELD: gas industry.

SUBSTANCE: invention relates to gas pumping units with high-temperature gas-turbine engines as drives. Invention objective is to increase efficiency of gas turbine engines with high-temperature turbines. Solving said task is achieved in a gas transfer unit comprising a gas turbine engine with a compressor, a combustion chamber and a turbine, a free turbine and a discharge compressor, fuel system and a synthesis gas system, which comprises a second gas bleeding system and an air bleed system from behind the compressor, an ejector-mixer to which are connected the second gas withdrawal system and the air bleed system, in series, the first heat exchanger installed in the exhaust device and the second heat exchanger installed on the housing of the chamber and the catalyst are connected to the outlet from the ejector-mixer. At that, the auxiliary fuel header is made inside the nozzle plate or on it and with additional channels it is communicated with nozzles of synthesis gas installed on the injector plate between fuel-air injectors, and the catalyst is placed in nozzles of synthesis gas.

EFFECT: higher efficiency of gas transfer units with high-temperature GTE as a drive.
