Title:
THERMAL STORAGE POWER GENERATION SYSTEM AND THERMAL STORAGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/190040
Kind Code:
A1
Abstract:
[Problem] To provide a thermal storage power generation system and a thermal storage device making it possible to achieve a heating unit and a thermal storage unit of suitable structures. [Solution] According to one embodiment, this thermal storage power generation system is provided with a thermal storage unit that comprises a thermal storage material for storing heat, and that uses the heat stored in the thermal storage material to heat a heat transfer fluid. The system is furthermore provided with a first heating unit that is provided within the thermal storage unit and heats the thermal storage material. The system is furthermore provided with a power generation unit for using the heat transfer fluid that has been heated by the thermal storage unit to generate power. The thermal storage unit is provided with: an inlet through which the heat transfer fluid is supplied when heat is being stored in the thermal storage material; and an outlet through which the heat transfer fluid is discharged when heat is being stored in the thermal storage material. The first heating unit is provided with one or more heat generation sources disposed to be inclined toward the inlet side, from between the inlet and the outlet. The first heating unit heats the thermal storage material using the heat generated from the heat generation sources.
