Abstract

The applicability of differential thermal analysis to determine the fusibility behavior of coal ashes was investigated. The technique proved useful to obtain four specific temperature points. These are: the minimum sintering temperature, the softening point, the point of complete fluidity and the reaction temperature which is tentatively identified as the eutectic temperature. In addition, differential scanning calorimetry was used to determine the heat capacity of the ash powders between 100K and 850K. Ash heat capacities were correlated with ash constitution
