    摘要: A method for recovering energy from bleed air (68) from a compressor (20) of a gas turbine (12) is provided. The method includes directing bleed air (68) from a compressor (20) of a gas turbine (12) into a cooling unit (76). The bleed air (68) is compressed air from the compressor (20), and the bleed air (68) is not directed into a combustion chamber (18) of the gas turbine (12). The method also includes cooling the bleed air (68) within the cooling unit (76). The method further includes expanding the cooled bleed air (68) within a turbo-expander (72) to generate power.
