摘　　要：研究了垃圾焚烧后灰渣中固相氯受水分、氯化物、温度的影响向气态氯转化的规律。结果表明随着气氛中水汽含量的增加、灰渣中氯化钠含量的增加及温度的升高烟气中气态氯含量也增加,并且灰渣中固相氯含量越高受到的影响就越大。研究表明这是因为在高温条件下,垃圾焚烧灰渣中的氧化物和盐能与气氛中的H2O和O2之间相互作用,促使灰渣中的固相氯生成气态氯。The effects of the temperatures, moisture and NaCl on solid-state chlorine transforming to gas state chlorine in residue of waste incineration were studied. The results showed more chlorine in residue transformed to gaseous chlorine with increasing moisture,NaCl and temperatures. At the same time the research also shows chloride sulfates,oxides and other compounds can react each other with H2O,O2 in fume under high temperatures, which makes solid-state chlorine in residue transform to gas-state chlorine.
