摘　　要：以实际工程中固体蓄热装置的蓄热砖体作为研究对象,将蓄热砖体简化为仿真模型,添加不同蓄热材料属性,通过定容及定功率两种分析路径,得出现有几种蓄热材料基于实际工程结构的温度场变化。结果表明:镁砖、硅砖、陶瓷在定容分析中最终时刻的蓄热温度差值率分别为:1.15、0.82、1.31,在定功率分析中最终时刻的蓄热温度差值率分别为:1.36、0.73、1.47,由此得出在性能方面,镁砖是现有固体蓄热材料中最优蓄热材料,相比硅砖、陶瓷蓄热材料,其基于工程结构的蓄热温差范围小,单位蓄热密度高。Taking the regenerative brick body of the solid heat storage device in practical engineering as the research object, the heat storage brick body is simplified into the simulation model, the properties of different heat storage materials are added, and the temperature field changes of several existing heat storage materials based on the actual engineering structure are obtained by two kinds of analysis paths of fixed capacity and fixed power. The results show that the difference rate of heat storage temperature in the final moment of magnesium brick, silicon brick and ceramics is: 1.15, 0.82 and 1.31 respectively, and the difference rate of heat storage temperature in the final moment in the fixed power analysis is: 1.36, 0.73 and 1.47 respectively, which leads to the result that allording to the performance, Magnesium brick is the optimal heat storage material in the existing solid heat storage materials, compared with silicon brick and ceramic heat storage materials. Its heat storage temperature difference range based on engineering structure is small, and the unit heat storage density is high.
