摘　　要：为了实现燃煤机组烟气排放达到最新环保标准,通过烟气调质提高电除尘器的效率是现阶段成效明显的一种手段。从不同烟气调质技术入手,以具体电厂为研究对象,分析了烟气调质对电除尘器工作效率的影响。结果表明:煤炭中的含硫率与灰分电阻率成指数下降关系,通过调质能够改变灰分电阻率,进而达到提高除尘效率的目的,这对改善电除尘性能有重要的参考意义。In order to achieve the latest environmental protection standards for flue gas emissions from coal-fired units, the efficiency of improving the electrostatic precipitator through flue gas conditioning is a means of obvious effect at this stage. The effect of flue gas quenching on the working efficiency of electrostatic precipitator was analyzed. The results showed that the relationship between the sulfur content in coal and the ash resistivity index decreased ,through the quenching and tempering can change the ash resistivity ,and thus achieve the purpose of improving the efficiency of dust,which improve the performance of electrostatic dust has important reference value.
