Different CaO Content Influence on Fusibility of Coal Ash

Abstract:

Selecting the Zichang coal as the sample coal, the chemical composition of the ash is analyzed with X-ray diffraction. The fusibility of coal ash temperature is measured for the ash with the different CaO content. The results shows that fusibility of coal ash drops with the increasing CaO content until it reaches 3.0%; then it increases with the increasing CaO content. We can explain this behavior by SiO2–Al2O3–CaO ternary phase diagram. The temperature of fusibility is lower when the additive amount reaches 3.0%~3.5% of coal.
