Title:
GEOTHERMAL EXCHANGER AND GEOTHERMAL POWER GENERATING SET
Document Type and Number:
Japanese Patent JP2021181780
Kind Code:
A
Abstract:
To provide a geothermal exchanger which can stabilize a temperature and a flow rate of steam to be produced while being adapted to a situation of a temperature change of a well even in a situation that a temperature of withdrawn geothermal energy is not stabilized, can efficiently perform heat exchange even if using a geothermal zone in a middle-low temperature which is equal to, or lower than about 180°C, and can increase a geothermal energy sampling amount by increasing the number of places being objects of a geothermal development.SOLUTION: A geothermal exchanger 1 comprises a pressure water heater 14 for heating pressure water which is withdrawn on the ground, and heating by the pressure water heater 14 is performed by an external heat source other than a heat source which is acquired from a geothermal zone. The geothermal exchanger also comprises a circulation water heater 17 for heating water which is accumulated in a first circulation water tank 16, and heating by the circulation water heater 17 is performed by the external heat source other than the heat source which is acquired from the geothermal zone.SELECTED DRAWING: Figure 1
