Abstract：Combining with international coal ash fusibility determination method, the fusibility of coal ash was studied using thermo - mechanical analysis ( TMA ). The results showed that: international coal ash fusibility determination method cannot describe the coal ash fusibility under high temperature quantitatively, but TMA can not only obtain the fusibility of coal ash and the dynamic change of coal ash fusibility under high temperature during the whole heating process, but also at the same time, obtain the fusion rate of ash under high temperature, so the fusibility of coal ash could be determined quantitatively using TMA, the design and operation of wet bottom boiler and gasifier could be guided.
