Abstract:
A gas turbine power plant having no intercooler for compressed air and comprising:a compressor for compressing air; a combustor for burning fuel with compressed air from said compressor to produce combustion gas; a turbine driven by the combustion gas; a generator driven by said turbine to produce electric power; a regenerative heat exchanger, heating the compressed air with the heat of exhaust gas of said turbine and having a water spray arranged therein for spraying water droplets onto the compressed air therein; a spray device directly communicating with said compressor for spraying water onto compressed air of high temperature from said compressor to humidify the compressed air, the compressed air being led to said regenerative heat exchanger; and a further spray device for spraying water on to air to be sucked into said compressor.
