Wear is the most common problem in CFB boiler,which has a great impact on CFB boiler safely operating.Numerical simulating the wearing process of plated superheater in a CFB boiler is proved by CFX program and the result of wear is analyzed.It is concluded that tube failure was caused by wear which was resulted by distortion of plated superheater.Based on the conclusion,further improvement measures are given.
