摘要
简述了电厂高温锅炉管道的寿命评估方法——持久强度法、蠕变损伤法以及蠕变曲线逐步外推法,深入讨论了其可靠性,并指出了应注意的问题。结果表明:持久强度法可靠性差,蠕变损伤法及蠕变曲线逐步外推法可靠性较高。
Life evaluation methods of high temperature boiler tube in Power Plant-high temperature strength method, creep damage method and creep curve extrapolation method are proposed in this paper. These methods＇s reliability is discussed deeply. Noticeable problems are also Pointed out in this paper. The results are that high temperature strength method isn＇t reliable, Creep damage method and Creep curve extrapolation method are reliable.
