Synergistic Effects of CaO and MgO on Ash Fusion Characteristics in Entrained-Flow Gasifier

Ash fusion temperatures (AFTs) are important parameters influencing the stable operation of industrial entrained-flow gasifier. It is well known that the separate addition of CaO and MgO can ameliorate the ash fusibility. However, the synergistic effect of CaO and MgO on the ash melting characteristics is still unclear. For this sake, the ash fusion temperature analyzer (AFTA), X-ray diffraction (XRD), Raman spectrum, and FactSage thermodynamics...
