在循环流化床的锅炉中,有许多部件是在高固体颗粒浓度的不断冲刷环境下工作的。这些部件的磨损问题日益突出,严重影响了锅炉机组的安全经济运行。循环流化床锅炉中,部件的磨损主要表现在冲蚀磨损。所谓的冲蚀磨损,是指当流体或固体颗粒以一定的速度或角度对材料表面进行冲击所造成的磨损。冲蚀磨损分为两种类型,一种为冲刷磨损, In circulating fluidized bed boilers, there are many components that operate at constant high concentrations of particulate solids. The wear of these components has become increasingly prominent, seriously affecting the safe and economic operation of the boiler unit. Circulating fluidized bed boiler, parts wear mainly in the erosion wear. The so-called erosion wear, refers to the fluid or solid particles at a certain speed or angle of impact on the surface of the material caused by wear and tear. Erosion wear is divided into two types, one for erosion wear,
