In a combined cycle power system having a gas turbine and one or more bottoming cycle expansion turbines for driving one or more generators, compressor inlet air to the gas turbine is cooled. An extraction is taken from the distillation condensation sub-system of the Kalina cycle and throttled to a lower pressure, with a corresponding temperature drop for supply to a low pressure evaporator in heat exchange relation with ambient air flowing to the compressor inlet to cool the ambient air. The partially evaporated multi-component mixture exiting the low pressure evaporator is returned to the spent vapor stream from the low pressure expansion turbine for combination therewith and condensation. Consequently, compressor inlet air inlet to the gas turbine is cooled, thereby increasing mass flow and turbine output.

[ What is claimed is:] [1.] In a combined cycle power generating system having a plurality of turbines, including a first turbine and a gas turbine having a compressor, said turbines being drivingly coupled to one or more generators for producing electricity, and a distillation/condensation sub-system, a method of cooling ambient air entering the gas turbine, comprising the steps of:(a) expanding a working fluid comprised of a mixture of dissimilar components having different boiling points at the same pressure through said first turbine and generating a spent stream of said mixture of dissimilar components;(b) condensing said spent stream in said sub-system;(c) passing inlet air for the compressor of the gas turbine in heat exchange relation with said condensed spent stream in a first heat exchanger to cool the inlet air entering the gas turbine compressor;(d) flowing the cooled inlet air into the compressor of the gas turbine; andpassing the spent stream of step (a) through low and high-pressure condensors to provide first and second condensed spent streams, respectively, and passing the compressor inlet air in heat exchange relation in said first heat exchanger with the second condensed spent stream forming a first heated stream of dissimilar components.
