摘要
该文计算分析了锅炉受热面管子热应力松弛，内壁氧化膜生长及管子壁厚损失的进展过程及它们在管子破坏中的作用，并把分析结果用到高参数锅炉管子寿命计算中，得到了合理的结果。
Abstract In this paper the relaxation of thermal stress in heat absorption tubes of boilers is mathematically analyzed, as well as the growth of the tubes' oxidized layers, the progressive diminuation of the tube wall thicknesses and its role in tube failures. Results of the analysis have effectively been applied to life assessment of boiler tubes operating with high steam parameters.
