Abstract
The present invention relates to an air humidifier for adding moisture to a working medium of a gas turbine for humidification, and gas turbine electric power generation equipment for driving the gas turbine by the working medium of high moisture to general electricity. An object of the present invention is to reduce pressure loss of burned exhaust gas of the gas turbine to improve output or efficiency of electric power generation. There comprises a humidifier (3), a combustor (5), a turbine (6), a generator (7), and a water recovery unit (10), further comprises an exhaust gas reheater (11) for heating burned exhaust gas discharged from the water recovery unit by surplus water discharged from the humidifier.

18. Gas turbine electric power generation equipment comprising:
-
a compressor for compressing air;
a spraying device for spraying water to the air to be supplied to said compressor;
a humidifier for adding moisture to the compressed air;
a combustor for generating combustion gas by humidified air obtained by said humidifier and fuel;
a turbine driven by the combustion gas generated by said combustor;
a water heater for heating water supplied to said humidifier by the exhaust gas of said turbine;
a water recovery unit to recover moisture in the exhaust gas discharged from said water heater; and
