| 摘 要： | 以PVC为HCl的释放源，采用热重法对不同气氛下各种钙化合物的脱氯特性进行了研究，探讨了各种钙化物的脱氯机理以及脱氯效率。结果表明和PVC作为氯化氢的释放源是可行的。3种钙化物中氢氧化钙的脱氯效果最好。氧化钙与氢氧化钙的脱氯机理基本相似。各种钙化物在不同气氛下的脱氯机理是不同的。燃烧状态下，在高温段钙化物脱氯产物氯化钙有分解迹象。

| Abstract: | The mechanism and efficiency of chlorine removal by calcium in different atmospheres were investigated by means of thermogravimetry.The PVC was used as the chlorine emission source.The results indicated that PVC can be used as the chlorine emission surce.The efficiency of chlorine removal by Ca(OH)\-2 is the best in the three calcium compounds.The mechanism of chlorine removal by Ca(OH)\-2 is the same as by CaO.The chlorine removal mechanism in different atmospheres is individual.CaCl\-2 will be decomposed under high temperature. |
