<P>PROBLEM TO BE SOLVED: To provide a power generator which is not required to raise the pressure of vapor-state air to the vicinity of a critical point. <P>SOLUTION: Liquid air injected to the liquefied layer of a cold insulation tank 8 is sprayed with high pressure to an electric heater 16 with a high pressure pump 14 and thereby, is heated and expanded to drive a turbine 17 for power generation and a power generator 18. Thereafter, vaporized air discharged from the turbine 17 for power generation is caused to flow into a heat exchanger 21 and is fed to the vaporized layer of the cold insulation tank 8 by the exhaust pressure of the turbine 17 for power generation, and the greater part of the vaporized air is released to the air from a pressure regulation valve 3, and remaining vaporized air is regenerated into liquid air by a refrigerating and liquefying machine 7. Further, the liquid air injected into the cold insulation tank 8 is forcibly fed to a heat exchange tube 22 with the high pressure pump 14, vaporized air discharged from the turbine 17 for power generation is forcibly fed to an expansion valve 4, is regenerated to liquid air by the expansion valve 4 and is fed into the cold insulation tank 8. <P>COPYRIGHT: (C)2012,JPO&INPIT |
