An analysis was made of the physicochemical characteristics of fly ashes from seven municipal solid waste incinerators (MSWIs) in China. Based on the analysis of these characteristics, the relationship between the components of raw refuse and total/soluble chlorine content, heavy metals distribution of fly ashes was discussed. The results show that heavy metal contents of fly ashes have close correlation with the components of raw refuse and refuse collection mode. Fly ashes have a high chlorine level (5.21%~14.49%) and soluble chlorine contributed 40.60%~83.96% to the total chlorine. Chlorine shows wide range content in different incineration plant, the fly ash of incineration plant from city on a comparatively developed economic level tends to have higher level of chlorine. The chlorine (especially soluble chlorine) in fly ash is mainly from kitchen wastes.
