Based on the fact that wear is a common phenomenon of circulating fluidized bed boiler,this paper examines the actual situation of expansion wear of main heating surfaces during the maintenance period of circulating fluidized bed boiler in a power plant.The causes are analyzed and preventive measures are introduced to reduce the frequency of explosion and leakage of boiler equipment and eliminate potential safety hazards,and the method of using wormwood smoke to detect leakage in air preheater is put forward.To achieve long-term safe and economic operation of the boiler.
