1. A gas turbine power generator comprising:
a compressor for compressing air;
a combustor for burning the compressed air and fuel;
a turbine driven by combustion gas produced in said combustor and driving said compressor and a generator;
a regenerative heat exchanger for exchanging heat between exhaust gas from said turbine and the compressed air led into said
combustor;
humidifying and cooling means for humidifying and cooling intake air flown into said regenerative heat exchanger, and
control means for controlling a flow rate of humidifying water supplied by said humidifying and cooling means to a value required
for making an intake air temperature at an inlet of said regenerative heat exchanger coincident with a saturation water vapor
temperature.
