Risk-Based Inspection (RBI) has been wide used in petrochemical industry all over world with good performance. But its application in power station boiler is rarely reported. The “four tubes” of the power station boiler, namely economizer, water-cooling wall, superheater and reheater tubes, are prone to blast due to the direct fire heating, and it causes non-plan shutdown and leads to severe influence to safety. In this paper, the failure mechanisms of power station boiler were analyzed, the calculation of modification factors for high-temperature smoke erosion and high-temperature creep was researched. Considering the specific situations in China, the probability of failure modification factor based on remaining life was proposed. Then, the method of economic loss calculation was established based on the differences between the petrochemical equipment and the power station boilers, and the proper classification scope was established according an investigation. At last, a superheater project was carried out, the risk was fixed and the proper management and inspection suggestions were proposed.
