Claims
- 1. Apparatus for retrofitting a combined cycle gas turbine system, and augmenting the power produced by the system which includes a main compressor having an inlet for receiving and compressing ambient air supplied to said inlet to produce compressed air, a combustor for heating the compressed air and producing hot gases, and a gas turbine responsive to said hot gases for driving said main compressor and supplying a load, and for producing hot exhaust gases, said apparatus comprising:
- a) a main conduit for receiving and carrying ambient air;
- b) a precompressor for receiving ambient air and producing precompressed air as an output;
- c) means for selectively connecting said inlet to either the output of said precompressor or to said main conduit;
- d) a direct contact heat exchanger for contacting and cooling air with cooler water for producing cooled air and warmed water;
- e) means for supplying said cooled air to said precompressor;
- f) a direct contact evaporative cooler for cooling the output of said precompressor with water; and
- g means for supplying said warmed water to said evaporative cooler.
- 2. Apparatus according to claim 1 including a filter for filtering air supplied to said inlet.
