GAS PUMPING UNIT Russian patent published in 2022 - IPC F02C3/00 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to gas pumping units, GPU, with high-temperature gas turbine engines as drives. The expected result was achieved in a gas pumping unit containing a gas turbine engine, an inlet device, a compressor, an annular combustion chamber with a heat pipe having an external heat wall and fuel-air nozzles on the nozzle plate connected through a fuel collector to the main fuel line, a turbine, a free turbine and an exhaust device, a synthesis gas system that contains a second a gas extraction system and an ejector line with an ejector mixer, to which the outputs of the second gas extraction system and an ejector line are connected, a preheating heat exchanger installed in the exhaust device is connected to the inlet from the ejector mixer, and a final heating heat exchanger with a catalyst is connected to the outlet of the ejector mixer through the second collector, characterized in that the ejector line is made in the form of a fuel ejector line, the final heating heat exchanger is installed inside the heat pipe on its outer heat wall and equipped with synthesis gas nozzles, and the catalyst is installed in the fuel channel of this heat exchanger.

EFFECT: task of the invention is increasing the efficiency of the unit.
