| Abstract: | The unit is forced to be shut down due to the lost of regulation function of included draft fan with abnormal sound during the startup.By inspection and analysis of operation and maintenance,the included draft fan going into stall with abnormal sound is mainly caused by moving blades drifting due to unsmooth blockage.It puts forward some prevention actions for the fault occurred,which provides advice for the operation and maintenance of the similar axial flow fans. |
