锅炉高温承压部件剩余寿命的评估及应用

Calculation Methods and Applications for Remaining Life of Boiler High Temperature Part

详细探讨了持久强度法、蠕变损伤法、Larson -Miller参数法、θ法计算锅炉高温部件剩余寿命 ,推导了各种方法的基本公式 。

The boiler high temperature parts are important components of the boiler, and their working condition affects the economy and safety of the whole unit. This paper discusses four calculation methods, including persistent strength method, creep law, Larson Miller parameter, and θ method, for remaining life of boiler high temperature part to forecast the remaining life of these components.
