摘要：

为了科学评价电站锅炉过热器的风险状况,制定合理的管理和维护策略,减少非计划停炉,研究基于风险检验（RBI）技术的过热器风险评定方法.研究过热器炉管的失效机理,建立适用于过热器炉管的高温烟气冲蚀因子和高温蠕变因子计算方法；结合我国超期服役、炉管材料初始缺陷等情况,提出基于剩余寿命参量的失效可能性修正系数；进一步确定合理的经济损失法来计算炉管失效后果,建立失效后果等级划分准则.通过对某末级过热器炉管失效的可能性和失效后果进行定量分析和计算,评定了炉管风险等级,制定了合理的管理和维护策略.
Abstract:

The risk assessment methodology based on risk-based inspection (RBI) was analyzed in order to evaluate the risk situation of the power station boiler superheater to establish the reasonable management, and maintenance strategy and reduce the non-plan shutdowns. The failure mechanism of power station boiler was analyzed, and the creep damage factor computing technical module and high-temperature smoke erosion thinning technical module for power station boiler tubes were conducted. The failure probability correction factor was presented based on the remaining life, considering China’s national condition, including the extended service and initial material defects etc. Moreover, the proper financial risk calculation method was established to assess the risk consequence, and the grade distinguish rule was established. The risk level was evaluated through the failure possibility and consequence quantitative analysis and calculation of a superheater, and the reasonable management and maintenance strategy was established.
