Gas turbine electric power generation equipment and air humidifier

Gas turbine electric power generation equipment comprising:

• a humidifier for increasing at least one of a quantity of steam, relative humidity, and absolute humidity of 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;
• an electricity generator driven by said turbine to generate electricity;
• a first heat exchanger for heat-exchanging between the burned exhaust gas discharged from said turbine and water supplied to said humidifier;
• and a water recovery unit for condensing moisture in the burned exhaust gas discharged from said first heat exchanger, said equipment further comprising:
• a second heat exchanger for heat-exchanging between a part of water obtained by said first heat exchanger and the burned exhaust gas discharged from said water recovery unit.

Gas turbine electric power generation equipment comprising:

• a compressor for compressing air;
• a humidifier for adding moisture to the compressed air obtained by said compressor;
• 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;
• an electricity generator driven by said turbine to generate electricity;
• a regenerator for heating said humidified air supplied to said combustor by the burned exhaust gas discharged from said turbine;
• a water heater for heating water supplied to said humidifier by the burned exhaust gas discharged from said regenerator;
• and a water recovery unit for cooling the burned exhaust gas discharged from said water heater to recover moisture in said burned exhaust gas, said equipment further comprising:
• an exhaust gas reheater for heating the burned exhaust gas discharged from said water recovery unit by a part of water obtained by being heated by said water heater, said water heater heating waste water discharged from said exhaust gas reheater to supply it to said humidifier.
