摘　　要：针对锅炉布袋压差升高的现象,进行烟气含湿量高和烟气温度低的分析,通过恢复净烟气清灰系统、减少锅炉掺烧燃气量以及关小引风机挡板等措施,有效遏制了布袋压差升高趋势。The pressure differential rise in boiler bag filter was analyz ed from high moisture content in flue gas and low flue gas temperature. The trend of pressure differential rise was restrained after restoring the flue gas ash cleaning system, reducing blended gas into the boiler, and closing a little the induced draft fan baffle.
