结合国标灰熔融性测定方法，利用热机械分析仪(TMA)对煤灰进行灰熔融性的测试研究。研究结果表明：国标灰熔融性测定方法得到的煤灰熔融特征温度无法定量描述煤灰在高温下的熔融行为，而 TMA 不仅能够获得煤灰的熔融性以及煤灰在整个加热过程中的熔融动态变化，同时可获得煤灰在高温下熔融的速率，因而可利用 TMA 定量测定灰熔融性，以指导液态排渣锅炉和气化炉的设计和操作。

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.
