循环流化床煤与生活垃圾混烧过程中HCl的排放

Hydrogen Chloride Emission During The Co-combustion of Municipal Solid Waste in A Circulating Fluidized Bed

在０．２ＭＷｔｈ循环流化床上进行垃圾与煤混烧实验．测量ＨＣｌ排放浓度，探讨城市生活垃圾掺烧比率和床层温度对ＨＣｌ排放浓度的影响．实验结果显示，在混烧过程中，随垃圾加入量的增加。ＨＣｌ排放量增加，温度对ＨＣｌ排放浓度的影响很小。垃圾中Ｃａ／（Ｓ＋０．５Ｃｌ）摩尔比对ＨＣｌ自脱除有影响．采用三相流态化垃圾净化系统时，ＨＣｌ在尾气净化系统中的脱除效率高于８０％。

Tests on the co-combustion of municipal solid waste (MSW) and coal were performed in a cirulating fluidized bed and focused on the hydrogen chloride (HCl) emission. The results show that the addition of MSW leads to higher HCl emission. Cholorine rentention have strong correlaton with Ca/(S+0.5Cl) molar ration. The hydrogen chloride can be effectively removed from the flue by gas cleaning system and the retention efficiency are higher than 80%.
