摘　　要：本文针对1台运行超过10×10^4h的300MW机组电站锅炉进行了寿命评估研究，定量评估了该炉受热面当前状态。同时引入敏感性指标，定量研究了不同受热面处当量温度T及应力σ对寿命的影响程度。寿命评估结论及建议对该炉的运行及检修具有有益的指导作用。The life assessment was performed for a 300MW power plant boiler whose service life is more than 100,000h. The current condition of this boiler＇s heating surfaces was quantitatively assessed. Meanwhile, the sensitivity parameter was adopted and the influence of equivalent temperature T and stress σ at different heating surface were quantitatively evaluated. The conclusion and advice of life assessment are helpful for the boiler＇s operation and examination.
