Experimental Study on Optimization of Thermal Shock Resistance of Solid Heat Storage Components
摘要
Abstract
To address the problems of poor thermal shock resistance and short service life of solid heat storage components in solid heat storage electric heat-ing devices,an experimental study on the thermal shock resistance of such components was carried out.The main material was selected as MgO,and the addi-tive materials were fine Fe2O3 powder and fine ZrO2 powder.By adjusting the ratio of the three materials,solid heat storage components with better thermal shock resistance were explored,and the operation pro-cess of the solid heat storage electric heating device was simulated.The experimental results show that when the mass ratio of sintered magnesia,Fe2O3,and ZrO2 is 86.4∶9.6∶4.0,the solid heat storage component exhibits a small attenuation rate of thermal conductiv-ity and specific heat capacity after repeated high-low temperature shock tests.The simulation results indi-cate that the solid heat storage electric heating device equipped with the optimized solid heat storage compo-nent has the lowest frontsurface temperature and the best thermal shock resistance.Compared with the origi-nal device,the service life of the device using the opti-mized solid heat storage component is improved.关键词
