摘要：

In this paper, a solid heat storage device with group switching is designed, based on this, complete the building of the experimental device with total heating power of 150 kW, simulate the temperature field distribution of furnace body with a numerical method of establishing the unsteady values of thermophysical parameters, and compare with the fixed value parameters to get the temperature curve and thermal storage curve of thermal physical parameters. Through numerical simulation and experimental data combination method, determine the feasibility of the numerical method of non-fixed value method. A heating mode of grouped switching is designed to analyze the heat storage and temperature of the solid regenerator with grouped heating. The results shown that the temperature gradient distribution range of the whole heating furnace is large, and the temperature of the sensor point is temperature difference. The temperature gradient distribution range of the furnace body heated by grouping is relatively narrow, and the temperature between sensors is almost equal. Under the same regenerative target temperature, the regenerative heat is increased by 6.0%. © 2021, Solar Energy Periodical Office Co., Ltd. All right reserved.
