  • The Zhujixi washed coal has high ash fusion temperature which were studied by adding fluxes calcium carbonate, ferric oxide, complex flux and dolomite. The results indicate that all fluxes can reduce the ash fusion temperature which is varied depending on different species and mass of fluxes addition. Ash fusion temperature can remarkably be reduced by adding small amount of complex flux or dolomite. By using thermodynamic FactSage software, the mineral compositions at high temperature of coal ash with flux were studied. This will be helpful to explain how the fluxes can improve the fusion properties.
