Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Characteristics of high alkali in Zhundong coal ash may cause ash‐related slag discharge problems at entrained‐flow‐bed (EFB) gasifier. In this study, through exploring melting characteristics and viscosity–temperature characteristics, it is found that MN05, MN14, and MN23 show low FTs (< 1160°C).
