Abstract:
A gas turbine installation comprising a compressor which compresses air, a combustor which combusts the compressed air by the compressor and fuel, a turbine which is driven by combustion gas produced in the combustor, a regenerative heat exchanger which performs heat exchange between exhaust gas exhausted from the turbine and at least a part of the compressed air supplied to the combustor and a water spraying device which sprays water into intake air to the compressor or into the compressed air compressed by the compressor, wherein the regenerative heat exchanger is comprised by dividing into upstream side unit and downstream side unit with reference to flow direction of the compressed air, and the flow passage cross sectional area of the downstream side unit is formed small with respect to that of the upstream side unit.
