DEVICE FOR COOLING CYCLE AIR OF A GAS TURBINE UNIT Russian patent published in 2023 - IPC F02C3/00 F02C7/12 

FIELD: gas turbine units.

SUBSTANCE: invention can be used to cool cycle air before supplying it to an axial compressor, to increase the efficiency and economy of gas compressor units. The device for cooling cycle air of a gas turbine unit contains a gas turbine unit with a compressor, a combustion chamber, a gas turbine, a smoke exhauster, a heat exchanger, an air mixing device and an absorption lithium bromide refrigeration unit. The selection of exhaust gases for operation of the absorption lithium bromide refrigeration unit is carried out by a smoke exhauster from the exhaust shaft. The heat exchanger and the air mixing device are installed in the complex air cleaning device.

EFFECT: implementation of the invention provides a solution to the following technical problems: reduction of electricity consumption, facilitation of the technological process of cooling cycle air, excluding the coolant in the role of water, and ensuring versatility of the system. Invention improves the efficiency, environmental friendliness and economy of gas turbine units.
