摘　　要：由于设计的煤质与实际生产中煤质相差较大,致使动力分场锅炉除尘系统不能满足生产需要,通过增大布袋过滤面积及除灰装置扩容等措施,减小除尘系统阻力,增加布袋使用寿命,降低除尘器出口烟气粉尘浓度,保证脱硫系统正常工作,确保环保达到要求。Because the coal quality in the actual production is largely different from the coal quality designed by the power station ,the boiler dust removal system from the original design could not meet the production in the power plant . Take measures of increasing the bag filtering area and expanding the dust removal system ,etc . ,for reducing dust removal system resistance ,extending the bag life , reducing flue dust concentration from the precipitator outlet ,and ensuring the desulfurization system to operate normally and the environmental protection to meet the requirements .
