<p>PROBLEM TO BE SOLVED: To provide a geothermal power generation system capable of increasing an amount of steam supplied to a steam turbine and increasing power generation amount without increasing the flow volume of gas-water mixture fluid of hot water and the steam pumped up from the underground.SOLUTION: An absorption heat pump including a regenerator 63, a condenser 64, an evaporator 61, an absorber 62, and the like; a high-pressure gas-water separator 51H; and high-pressure steam turbine 52H are installed in a conventional geothermal power generation system. A conventional gas-water separator and a conventional steam turbine are used as a low-pressure gas-water separator 51L and a low-pressure steam turbine 52L, respectively. A geothermal power generation system with the absorption heat pump absorbs heat from the hot water returned to the underground, generates high-temperature heat, heats the hot water pumped up from the underground with this heat, and generates high-temperature high-pressure steam. The generated steam is supplied first to the high-pressure steam turbine 52H and then to the low-pressure steam turbine 52L. The steam generated when the hot water is pumped up from the underground is supplied to the low-pressure steam turbine 52L.</p> |
