Title:
GEOTHERMAL POWER GENERATOR
Document Type and Number:
Japanese Patent JP2021004603
Kind Code:
A
Abstract:
To provide a steam generator, a geothermal power generator and a geothermal power generation method capable of improving power generation efficiency by effectively utilizing heat obtained from a geothermal region on the ground.SOLUTION: A geothermal power generator (200) generating power by applying a medium heated by heat of a geothermal region as a heat source, has: a binary power generator (B) generating power by transferring the medium of high temperature absorbing heat from the geothermal region to a heat exchanger on the ground in a liquid state so that steam is not generated, by adding a pressure higher than an evaporation curve, using the medium in the heat exchanger as the heat source and evaporating a working medium (M1-M3) having a boiling point lower than the medium; and a storage portion (4) for keeping a water level of the medium cooled by heat exchange in the heat exchanger, constant in the entire system.SELECTED DRAWING: Figure 16
