HEAT STORING TANK AND SOLAR HEAT POWER GENERATION SYSTEM USING HEAT STORING TANK

摘要

PROBLEM TO BE SOLVED: To provide a heat storing tank capable of efficiently storing heat, and a solar heat power generation system using the heat storing tank.SOLUTION: A heat storing tank 40 storing heat supplied from a predetermined heat source has a heat storing tank body 41 in which a first heat transporting medium 21 transporting the heat supplied from the predetermined heat source flows into a lower part in the tank and flows out from an upper part of the tank in a heat storing mode storing the heat in the heat storing tank 40, a heat storing agent 42 arranged in the tank of the heat storing tank body 41 in a state of being mixed with the first heat transporting medium 21 having larger specific gravity than that of the first heat transporting medium 21, and separating from the first transporting medium 21 even though being mixed with the first heat transporting medium 21, and a heat exchanger 43 through which a second heat transporting medium exchanging heat with the heat storing agent 42 mixedly exists with the first heat transporting medium 21 through a heat exchanging surface in the tank of the heat storing tank 41 and transporting the heat to a predetermined supplying destination flows in a heat radiation mode radiating the heat stored in the heat storing tank 40.
