摘要
大型电站锅炉高温受热面管内氧化皮生长及脱落问题已成为影响锅炉安全运行的主要矛盾。介绍了一种锅炉高温受热面管内氧化皮应力分析解析方法,并针对某600 MW超临界电站锅炉末级过热器的TP347H和T91 2种管材进行了计算分析,得出了停炉过程中氧化皮的应力、应变状态和可能的失效模式。
The oxide scale of the high temperature heating surface tube growth and exfoliat- ion problem has become one of the main contradictions that affect the safe operation of the u- tility boilers. Described an analytical method for the stress analysis of the oxide scale of the high temperature heating surface tube of the utility boiler, calculated and analyzed the TP347H and T91 tube of the final superheater of a 600 MW supercritical boiler, obtained the stress and strain state and possible failure modes of the oxide scale in the shutdown process.
