P91钢高温联箱失效的定量风险评估
摘要
采用随机性方法
对某超临界600MW机组锅炉的P91钢高温过热器出口联箱建立失效概率模型
计算出联箱失效概率
并对影响失效概率的因素进行了分析
结合失效后果
给出了定量风险评估的结果
并据此提出了该600 MW机组锅炉高温联箱的维修策略。
Abstract
By using method of randomness
a failure probability model for outlet header of the high-temperature superheater made from P91 steel for boiler of supercritical 600MW unit has been established
the failure probability of said header being calculated
and factors affecting the failure probability being analysed.Combining with the concequences of failure
the quantitative assessment result of risk has been given
and the maintenance strategy of high-temperature header of boiler for 600MW unit being put forward on this basis.
