摘　　要：对我国目前4种垃圾焚烧技术实际运用所产生的灰渣进行取样分析.飞灰中氯的沉积多以氯化物形态存在,氯化物经过氧化,产生氯气,穿过疏松的灰渣膜向金属扩散发生腐蚀.飞灰中硫含量随着炉型变化差异较大.氟、磷的含量较小,与垃圾组分含量密切相关.制约过热蒸汽温度提高的主要影响因素是灰渣中氯、硫的腐蚀.Ash and slag of municipal solid waste(MSW)incineration were sampled and analyzed from four kinds of MSW incieration technology used at present.Most content of chlorine transfers to chloride in ash and slag of MSW incineration.Chlorine is formed from chloride through oxidation reaction and penetrates the protective oxide scale to the metal to cause corrosion.Sulfur content in ash and alag greatly varies with MSW in cineration technology.Content of fluorine and phosphonium relatively is lower and mainly depends on that in MSW.Corrosion of chlorine and sulfur limits the further lifting of superheated steam temperature.
