EXHAUST SYSTEM OF GAS TRANSFER UNIT Russian patent published in 2019 - IPC F01D25/30 E04H12/28 F23J13/00 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, namely to gas transfer units with gas turbine engine, converting energy of fuel combustion products into mechanical and discharging exhaust gases into atmosphere, and can be used in gas industry, in particular, on natural gas liquefaction complexes. Exhaust system of gas transfer unit includes housing with exhaust pipe and bypass gas duct, heat exchange coil, separating device, guiding off-gases into exhaust pipe and/or bypass gas duct, wherein heat exchange coil is made of sections of pipes fixed by guide lodgments, with steeply bends, in heat exchange coil is used hydrocarbon heat carrier, separating device is implemented in the form of double dampers, also the exhaust system is equipped with an external air fan with two discharge air ducts, one of which is placed in the exhaust pipe between the heat exchange coil and the separating device for cooling air supply, and second is used to supply sealing air between dual gates depending on their position.

EFFECT: higher efficiency of heat removal from exhaust gases of gas turbine engine.
