Research Abstract

We proposed a new recycling system for municipal solid waste incineration fly ash-"WCCB". "W" means washing ; the first "C" means calcinating : the "CB" means changing the treated fly ash with bottom ash into raw material in cement industry to cut down the amount of residue and its chlorine content as much as possible. By using sodium reagents as an additive in the flue gas treatment, the chlorine in fly ash was easily removed in both washing and calcinating processes and the amount of the final residue was significantly reduced. The inhibition mechanism of dioxin formation on fly ash by using the sodium reagent was revealed.
