通过对锦州发电厂６号锅炉引风机积灰振动原因的分析，提出了风机的改造方案。改造后实际检查和试验结果表明：引风机性能完全满足锅炉带额定负荷的要求，从根本上解决了引风机磨损和积灰振动等问题，达到预期目的，该方法已在４、５号炉引风机上推广应用。
Through the analysis of the reason of the fouling vibration of the induced draft fan of No. 6 Boiler in Jinzhou Power Plant, the reformation plan of the fan is put forward. The actual inspection and test results show that the performance of the induced draft fan completely meets the requirements of the rated load of the boiler, and fundamentally solves the problems of draft fan wear and fouling and vibration and achieves the expected purpose. The method has been applied in No.4 and No.5 furnaces Fan on the promotion and application.
