| Outline of Final Research Achievements |
For producing chemically stable slag from municipal solid wastes melting, this study dealt with kinetic study on the dissolution of free-CaO, which causes pop-out phenomena, into CaO-SiO2-Al2O3 molten slag.
The effects of slag compositions, melting temperature, and initial particle diameter of free-CaO on dissolution rate of CaO particle were experimentally investigated. The rate expression for the dissolution of CaO particles into molten slags derived from the film theory enabled to predict the time required for complete dissolution of free-CaO into molten slags.
