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

FIELD: gas pumping units.

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, free turbine and discharge compressor, fuel system and synthesis gas system, which comprises second gas bleed system and air bleed system due to compressor, ejector-mixer, to which outputs of the second gas bleed system and the air bleed system are connected, to the outlet of the ejector-mixer there connected in series to the first heat exchanger installed in the exhaust device, and a second heat exchanger mounted on the housing of the chamber and a catalyst. At that, the catalyst is installed inside the auxiliary fuel collector, which is made inside the nozzle plate or on it and with additional channels is communicated with air channels of the injector plate.

EFFECT: higher efficiency of gas transfer units with high-temperature turbines.
