Filter-bag failure analysis of steel sintering flue gas desulphurization system
某钢厂烧结烟气脱硫系统滤袋失效原因分析

In order to know the reason of selecting PPS as filter media in sintering flue gas desulfurization system,the features of PPS were analyzed in this work.SEM,EDS energy spectrum analysis and loss on ignition experiments were used to analyze chemical composition of filter bag which is a failure filter-bag from one steel sintering flue gas desulfurization system.It was found that the main reason of failure is the mixed glass fibers in the material.This work provided the basis for choosing the filter-bag in future projects,minimized the unnecessary losses,and ensured the normal operation of flue gas desulfurization system.
