Patent ID: 8640438

Claim:
High humidity gas turbine equipment comprising: a compressor for compressing air; a combustor for combusting compressed air generated by the compressor and a fuel; a gas turbine driven by combustion gas generated by the combustor; a generator for generating power by being driven by the gas turbine; a humidifier for humidifying the compressed air by bringing the compressed air from the compressor into direct contact with hot water; a regenerative heat exchanger for heating the compressed air from the humidifier by exhaust gas of the gas turbine, and feeding the heated compressed air to the combustor; a first heating device for heating water recovered from the exhaust gas of the gas turbine by utilizing a factory exhaust heat medium from the outside to generate hot water for the humidifier; a second heating device for heating water by utilizing the exhaust gas of the gas turbine to generate steam or hot water to be supplied to the outside; a water recovering device for recovering water from the exhaust gas of the second heating device; a supply pipe system for supplying water recovered by the water recovering device to the humidifier; a circulation pipe system for reusing the water used in the humidifier, again in the humidifier; wherein the first heating device comprises heat exchangers that receive the factory exhaust heat medium provided in both of the supply pipe system and the circulation pipe system; and wherein the temperature of the factory exhaust heat medium introduced in the first heating device is lower than that of the exhaust gas introduced in the second heating device.
