Other AbstractThe vitrification parameter was investigated by cooling and solidifying the molten simulated municipal solid waste incinerator(MSWI) fly ash. The results indicated that the vitrification was unaffected by Cl and S from fly ash in melting process at 1350°C; the melt was more easily vitrified by air cooling than by in-furnace cooling; Ca2+ had more destructive effect on vitrification network structure than Na ion in the air-cooling condition, and the reverse happened in in-furnace cooling condition;Al ion played a dual role in the vitrification process; a part of B ion could replace Si ion to build the network structure as network former. O/F was defined, the empirical data of coefficient were given, and the condition for vitrification was obtained, i.e. O/F<3.2 in the case of in-furnace cooling and O/F<3.4 in the case of air cooling, which was validated by MSWI fly ash, sampled from MSWI plant in Shenzhen, vitrified with SiO2 and B2O3.
