GAS TURBINE

PROBLEM TO BE SOLVED: To solve a problem that a thermometer get wet due to sprayed water and temperature near to wet-bulb temperature is detected, in a cooling method for directly spraying water to intake air, and a problem that generation of droplets on an inner wall face of an intake port prevents accurate measurement of intake air temperature, in a method for cooling air by a heat exchanger, although several methods for measuring intake air inlet temperature are proposed, in regard to a gas turbine supplying cooled intake air to a compressor. SOLUTION: The gas turbine A is provided with the compressor 10 compressing intake air supplied from an intake port 11 and discharging the intake air from a discharge port 13, a combustor 30 combusting fuel by the air discharged from the compressor 10, a turbine 40 driven by combustion gas of the combustor 30, and a cooling device 50 cooling the intake air. The discharge port 13 is provided with temperature detection means 61, 62, 63 for detecting the temperature of the air discharged by the compressor 10. Based on the temperature detected by the temperature detection means 61, 62, 63, the temperature of the intake air is measured. COPYRIGHT: (C)2005,JPO&NCIPI
