利用热机械分析仪测定煤灰熔融性的研究
Study on using thermo-mechanical analysis to determinate the coal ash fusibility
摘要
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.关键词
