摘　　要：为了优化蓄热式烧嘴结构,提高其使用寿命,利用有限元分析软件对蓄热式烧嘴进行了热应力分析,通过对比实际情况验证了有限元分析的合理性,同时根据仿真结果并结合工艺特点对蓄热式烧嘴结构进行了优化,并对优化后的蓄热式烧嘴进行了热应力数值模拟及分析。结果表明,优化后的蓄热式烧嘴能有效解决传统蓄热式烧嘴热应力集中、换向时应力幅值大等问题,从而延长烧嘴的使用寿命。The thermal stress of regenerative burner was analyzed by a finite element analysis software in or-der to optimize its structure and prolong its service life, The comparative analysis of the results and the ac-tual situation verified the rationality of the finite element analysis method. According to the simulation results and process characteristics,the structure of the regenerative burner was optimized. The numerical simula- tion and analysis of thermal stress for the optimized regenerative burner were carried out. The results show that the optimized regenerative burner can effectively solve the problems of the traditional regenerative burner thermal stress concentration and the large stress amplitude during reversing ,and prolong the serv-ice life of the burner.
