Patent ID: 8151549

Claim:
A high humidity gas turbine equipment comprising: a turbine driven by combustion gas; a compressor, which compresses air; a humidifier, which brings the air compressed by the compressor into contact with feed water to humidify the air; a regenerative heat exchanger, which causes the air humidified by the humidifier to be heated by exhaust gas from the turbine; a combustor, which burns the air heated by the regenerative heat exchanger and fuel to generate the combustion gas, which drives the turbine; a deaerating equipment including a deaerating section, to which the feed water used in the humidifier for humidification of air and makeup water, comprising water recovered from the exhaust gas and external water to the humidifier, are supplied and which deaerates the feed water and the makeup water with steam, a water storage tank, in which the feed water deaerated in the deaerating section and the makeup water are stored, and a steam generating section, which causes the feed water and the makeup water in the water storage tank to be heated by the exhaust gas from the turbine to evaporate and supplies the steam to the deaerating section; and a feed water supply pipe, through which the feed water and the makeup water in the water storage tank are supplied to the humidifier.
