INTAKE AIR COOLING METHOD, INTAKE AIR COOLING DEVICE EXECUTING SAID METHOD, AND WASTE HEAT RECOVERY FACILITY AND GAS TURBINE PLANT EACH COMPRISING SAID INTAKE AIR COOLING DEVICE

摘要

An intake air cooling device (150) is provided with a water supply line (131) and a heat pump device (151). The water supply line (131) sends water to a waste heat recovery boiler (110) which generates vapor utilizing the heat of exhaust gas (EG) from a gas turbine (10). A heat pump device (151) transfers the heat of air (A), which is sucked in by the gas turbine (10), to water flowing through the water supply line (131), thereby cooling the air (A) and heating the water.
