| Popis: | Both the properties of slag and ash, and the processes of deposition and growth must be clarified in order to solve slagging trouble (1),(2) . This report presents the effective thermal conductivity measuring results of ash deposit and the estimating results of ash deposit internal temperature. The experiment was carried out by accumulating molten ash onto the heat transfer measuring probe disk. The main results are as follows. 1. Thickness of sintered layer decreases as the probe disk surface temperature increases. 2. The ash deposit average porosity and the ash deposit effective thermal conductivity are correlated with the distance from probe disk surface to measuring point. 3. Temperature at the interface between sintered layer and molten layer is estimated as IDT; initial deforming temperature of ash. |
