SOLAR THERMAL POWER GENERATION SYSTEM USING SINGLE HOT MOLTEN SALT THERMAL ENERGY STORAGE TANK

摘要

A single thermal energy storage tank is used so that costs can be reduced and an installation space can also be reduced compared to a case where two tanks, i.e., a high temperature tank and a low temperature tank are provided. In addition, the single thermal energy storage tank includes a porous block so that passage of molten salt can be more easily performed and flow pressure drop can be reduced. In addition, the porous block is configured by stacking a plurality of unit blocks so that the capacity of the single thermal energy storage tank can be easily adjusted. Furthermore, a plurality of single thermal energy storage tanks are connected in parallel so that the plurality of single thermal energy storage tanks can be selectively used according to an operation load and thus the solar thermal power generation system can easily cope with the operation load.

主权项

1. A solar thermal power generation system using a single hot molten salt thermal energy storage tank, the solar thermal power generation system comprising:
a solar collector that collects solar heat; a single thermal energy storage tank that is formed in a shape of a porous block so as to form a flow path on which molten salt heated from the solar collector passes and that forms heat of the molten salt as a layer and stores the heat; and a power generator that generates electricity by receiving the heat stored in the single thermal energy storage tank.
