| Abstract: | The characteristics of fly ash from two kinds of incinerators--pure MSW(municipal solid waste) grate incinerator and MSW-coal CFB incinerator weres analysed. The results show that these fly ashes had a similar size distribution. The concentrations of heavy metals in the fly ash of grate incinerator were higher than those of the fly ash of CFB. The leaching characteristics of heavy metals in MSW fly ash was depended on the pH of leachate. |
