Heat Release Simulation Research Based on Solid Heat Storage and Release Materials

Abstract To promote the actual investment of solid electric heat storage heating devices, three different heat storage and heat release materials are used to simulate and analyze the heat release. The results show that “magnesia brick has the best heat storage and release capacity in 10 hours”. In terms of average temperature performance, silica brick is the best, and the standard deviation of temperature reaches the maximum value at 8 h, which is 75.13 k. It is less than the maximum value of 99.70 k for magnesia brick and 114.93 k for solid waste ceramic brick. However, the manufacturing cost of silica brick is the highest, and the cost of solid waste ceramic brick is the lowest. Solid waste ceramic bricks can be preferentially selected under the condition of meeting the requirements of heat storage and release.
