<p>PURPOSE: A geothermal power-generation system using heat exchange between molten salt and working fluid and a method thereof are provided to generate electricity by rotating a turbine using heat exchange between molten salt and working fluid after storing solar heat or waste heat in the molten salt. CONSTITUTION: A geothermal power-generation system using heat exchange between molten salt and working fluid comprises a heat collecting part(100), a plurality of molten salt accommodating parts(300), an heat exchange part(200), a plurality of working fluid accommodating parts(400), a turbine part(600), and a generating part(700). The heat exchange part delivers a heating source of the heat collecting part to a heating source of the molten salt accommodating parts. The working fluid accommodating parts accommodate working fluid which is delivered by heat exchange. The working fluid accommodating parts surround each molten salt accommodating part and are separated with a constant interval on the ground. The turbine part is connected to the working fluid accommodating parts and generates mechanical energy using vapor which is generated in the working fluid accommodating parts. The generating part is connected to the turbine part and generates electric energy using the mechanical energy. The working fluid accommodating parts are made from a U-shaped pipe having a spiral fin to increase the heating surface area in the outer circumference. The vapor which is generated by evaporating of the heated working fluid flows in the turbine part through the exit of the working fluid accommodating parts.</p> |
