Research on Ash Fusibility and Viscosity-temperature Characteristics of High-calcium Shanxin Coal Ash

Coal ash fusibility and viscosity-temperature characteristic are the decisive indices to judge the operation of gasifiers.SiO2 was added to decrease the fusion temperature and improve the viscosity-temperature characteristic of the high-calcium Shanxin coal ash.The FactSage 6.2 software was used to deduce the phase change law when the coal ash melted under different temperature ranges.The changes of ash fusion temperature and viscosity caused by...
