PROBLEM TO BE SOLVED: To provide a hot spring heat power generation system using a hot spring water storage tank, capable of generating electric power even in existing spring facilities where device installation location is narrow or at a location at which it is difficult to secure a large quantity of cooling water necessary to generate electric power from hot spring heat, reducing failure risk and disassembly cleaning burden due to closed scale of an indirect heat exchanger, and achieving high efficiency generation of the electric power while suppressing degradation in power generation efficiency due to cooling of a power generation medium and transport power.SOLUTION: A closed loop circulation type hot spring heat power generation system configured so that a power generation medium is evaporated and gasified by a direct heat exchanger 2 in a hot spring water storage tank 1, generated steam is introduced into an expansion turbine 4 installed in an upper portion of the tank 1, the steam is formed into condensed liquid using cold water obtained from an adsorption or absorption refrigerator 9 using hot spring heat in the tank 1 as a drive source, and the condensed liquid is caused to flow again downward from the upper portion of the tank 1 into the heat exchanger 2 in the hot spring water storage tank 1, is constituted in the hot spring water storage tank 1 and the upper portion thereof. |
