Title:
ガスタービン吸気冷却システム
Document Type and Number:
Japanese Patent JP3561772
Kind Code:
B2
Abstract:
In a gas turbine inlet air cooling system that includes a heat exchanger to cool gas turbine inlet air which is taken from the atmosphere, by using chilled cooling water and a gas turbine using gas turbine inlet air as air for combustion and a chilled refrigerant supply apparatus to supply the chilled cooling water to the heat exchanger, the gas turbine inlet air cooling system has an adjustment valve that makes the cooling water of the cooling water return pipe heated by the heat exchanger join the chilled cooling water of the cooling water supply pipe that is supplied from the chilled refrigerant supply equipment. The gas turbine inlet air cooling system detects the temperature of the cooling water that is supplied to the heat exchanger with a temperature detector and controls the temperature of the cooling water by adjusting the opening of the adjustment valve. The present invention improves the gas turbine output by repressing the occurrence of drain water in the heat exchanger controlling the chilled refrigerant temperature to be supplied to the heat exchanger that cools the gas turbine inlet air.
