Beschreibung
Zusammenfassung:	A natural gas fired combined-cycle power generation system is provided with: a vaporization device, a cooling device, a circulation flow path, a pump, and a gas-turbine combined power generation device. The vaporization device includes: an intermediate medium evaporation section that causes heat to be exchanged between an intermediate medium having a coagulation point lower than that of water and water flowing out from the cooling device, to cause at least part of the intermediate medium to evaporate; and a liquified natural gas vaporization section that causes heat to be exchanged between the intermediate medium and liquified natural gas to vaporize at least part of the liquified natural gas.
