摘要

使用自行设计的燃煤烟气汞形态测量装置

在燃烧石煤的循环流化床锅炉上进行了汞排放及其控制试验研究。试验结果表明 :静电除尘器对汞的排放有一定的控制作用

除尘器后烟气中汞的含量明显低于除尘器前 ;烟气经过除尘器后汞的形态分布变化较大

排入大气的汞主要为单质态汞 ;燃煤中添加石灰石后

使得烟气中的气态汞向固态汞转化

有利于汞的脱除。

Abstract

Using selfdesigned measuring facility of mercury formation in flue gas from fuel coal

an experimental study on mercury emission and control has been carried out on a circulating fluidized bed （CFB） boiler firing stone coal. Results of experiment show that the electric precipitator （EP）has certain control effect for mercury emission

the mercury content in flue gas after EP is obviously lower than that before EP

the variation of mercury formation distribution in flue gas after EP being comparatively large. The mercury discharged into atmosphere is mainly mercury in single substance state. After adding limestone into fuel coal

transformation of gaseous state mercury into solid state meicury in the flue gas has occurred

being helpful for alleviating mercury.
