PROBLEM TO BE SOLVED: To suppress adhesion of a scale to a pipeline of a system utilizing geothermal hot water and to other equipment.SOLUTION: A geothermal utilization system such as a binary power generation system includes a heat exchanger 30 and a binary power generator 12. The binary power generator 12 utilizes heat of fresh water heated by the heat exchanger 30 and supplied through a fresh water pipeline 24. In the heat exchanger 30, a primary side flow passage and a secondary side flow passage are formed. The primary side flow passage extends from a primary side inlet to a primary side outlet above the primary side inlet. In the secondary side flow passage, fluid subjected heat exchange with fluid flowing in the primary side flow passage flows. A hot water supply pipeline 22 for supplying geothermal hot water extends from underground, and is directly connected to the primary side inlet 41 of the heat exchanger 30.SELECTED DRAWING: Figure 1 |
