Title:
GEOTHERMAL POWER GENERATION SYSTEM
Document Type and Number:
Japanese Patent JP2021152355
Kind Code:
A
Abstract:
To recover an output of a geothermal power generation system in which hot water is depleted, without receiving energy supply from the exterior.SOLUTION: Hot water pumped out from the underground is compressed by a booster pump, and is heated by a second-class absorption heat pump to increase the temperature, and steam with increased temeperature and pressure is supplied to a steam turbine. Since the temeperature and pressure of the steam in the steam turbine are increased, and the heat efficiency of the steam turbine is thus improved, a power generation amount of a generator in connection with the steam turbine can be recovered with less amount of hot water.SELECTED DRAWING: Figure 3
