Abstract
A process and system which improves the capacity and efficiency of a combined cycle power plant. A LNG supply system fuels the combined cycle plant. Gasified LNG in a combustor mixes with the air from the air compressor to provide the hot combustion gas for the gas turbine. The expanding LNG is used to chill a primary heat exchange fluid, e.g. water, which primary heat exchange fluid cools and densifies the intake air for the air compressor. Subsequently, the primary heat exchange fluid is used to condense the spent steam discharged from the steam turbine. The primary heat exchange fluid is then re-chilled and recycled to cool and densify the intake air.
