he causes of blade breakage in title induced draft fan with adjustable moving blades allocated for 1025t/h boiler of home-made 300MW unit at Zhujiang Power Plant in Guangzhou City have been analysed. It is considered that the main causes are as follows: (1) the quality of blade material isn't up to standard; (2) the quality of casting is bad; (3) the dynamic stress of blades in operation is larger. For these reasons
some measures
such as improving quality of the blades' material etc.
have been put forward
then the problem of blade breakage has been thoroughly solved.
