<p>PROBLEM TO BE SOLVED: To provide a heat storage device that has a wide range of temperature and an extended period of time, and also is effective.SOLUTION: The heat storage device is configured by: using a micro-perforated or foamed ceramic tube as a heat reception and heating element 1 of a heat receiving device 2; preventing heat dissipation with double transparent glass; performing capillary action water supply 5 or pump water supply; generating superheated steam; and using a glass tube or a ceramic tube with heat protection material wound circumferentially as external piping 6. The heat storage device uses salt (NACL), ionic liquid, ceramic heat storage material and rock as heat storage materials, and stores heat from low-temperature to moderate high-temperature. Multi-stage high temperature heat storage 3 (90-1200 degrees C) tanks are formed in order of descending temperature in each of several tanks, and in a nested structure with an insulated wall or an insulated bag, thereby achieving temperature gradient and safe storage. In use, the multi-stage high temperature heat storage tanks are sequentially switched and used in order of ascending temperature in each of several tanks.</p> |
