Abstract

Abstract: The induced draft fan and forced draft fan of four boilers in Huadian International Zouxian Power Plant were failed repeatedly since they were put into operation. Some improvement measures were adopted, and some results were obtained. The problems existed in erection and maintenance of axial flow fan with adjustable moving blade were presented. The diagnosis of mechanical failures occurred in fan operation was described, the failure reasons were analyzed, and the handling methods were given. All these can be used as reference for whom of same trade.

Key words: induced draft fan, failure diagnosis, analysis
