摘要
A compressor 1 for compressing the air which has an intake, a combustor 2 to generate the combustion gas burnt to be mixed with natural gas fuel and the compressed air compressed by the compressor 1, was generated by the combustor 2 In LNG cold utilization gas turbine including a gas turbine 100 having a turbine 3 driven by the combustion gas, and a load driven by the turbine, and the intake and is disposed in the intake system 36 that guides the intake air to the compressor 1 the extract air cooling system with the intake-air cooling device 6 for cooling, is installed in the extraction cooling system can be arranged to supply bleed air cooling system 16, 17 in the high-temperature portion of the 3 turbine bleed air extracted from the compressor 1 an extraction cooling system 45 for cooling the bleed air flowing down a casing cooling system 47 for cooling a casing of the turbine is installed in the turbine 3, the exhaust gas for discharging the exhaust gas to drive the turbine from the turbine 3 and an exhaust heat recovery device 7 for recovering the waste heat from the exhaust gas is installed in the system 15, the cooling medium of the heat recovery device 7 the intake cooling device 6, bleed cooling system 45, 46, and casing cooling device 47, LNG cold energy utilization gas turbine that is configured to use to cool the cold of this natural gas 35a by arranging to supply natural gas cooling system 35 natural gas as 35a.
