At this time, the solar heater 7 heats the metal heat storage medium 2 made of a casting structure while being provided with a temperature of 200 degrees or more and a height of 1200 to 1300 degrees according to the size of the solar tracking light concentrator 100.
- the metal heat storage medium 2 heated to a high temperature of 200 to 1300 degrees is made of molten iron scrap, etc., and can store heat within a melting point (1538 degrees) of the ferrous metal. Therefore, it is possible to provide a high heat storage property while configuring a small size of the metal heat storage medium (2).
- the heat energy stored in the metal heat storage medium (2) is double surrounded by the inner insulation wall 31 of the quadruple structure and the outer wall structure (4) of the concrete structure to reduce the heat loss of the metal heat storage medium (2). Since long-term preservation is possible while minimizing, the metal heat storage medium 2 does not cool without additional heating for several days in a state of heating once at a high temperature.
- a heat exchanger 6 having a spiral shape is installed inward of the metal heat storage medium 2, and a heat exchanger 6 is formed in a spiral shape by introducing a cold fluid into the supply pipe 61. After slowly heating while moving through the structure to be discharged through the drain pipe 62 to maintain a sufficient heat exchange time will be able to heat the fluid to a high temperature.
- the present invention is applied to a domestic boiler, and the metal heat storage medium 2 is used as a storage medium. If configured, it can be used for heating in winter, and heating with clean solar energy is possible.
- the heat storage temperature is lower than that of the present invention, and the chemicals are manufactured by forming a chemical substance, which has a problem of shortening the lifespan due to oxidation during long time use.
- the storage medium 2 is a cast product, it can be permanently used by a method such as anti-oxidation treatment of only the surface.
- the metal heat storage device provided in the present invention can be used for home solar boilers as well as industrial solar boilers, heat storage devices for power generation, and the like.
