Abstract:
Apparatus for augmenting power produced by a gas turbine comprising:a) a precompressor having a pressure ratio of about 1:1.15 that precompresses ambient air prior to supplying it to a compressor of the gas turbine when the temperature of the ambient air exceeds the design level thereby introducing temperature and pressure rises in the air supplied to the compressor of the gas turbine;b) an indirect cooler that indirectly cools precompressed air exiting the precompressor using liquid supplied thereto to a temperature approximately ambient air temperature;c) a secondary heat transfer cycle for cooling the liquid suppled to said indirect cooler; andd) a diverter that supplies cooled, precompressed air to the inlet of the compressor of the gas turbine when required and otherwise supplies ambient air to the inlet of the compressor of the gas turbine.
