The coal gasification for the synthetic gas needs high temperature reaction more than 1, 100°C. But at that high temperature, the ash in the coal is shown complicate behavior from soild phase to liquid phase.
The authors are considered on the behavior of the ash at high temperature in this paper.
As rising the ash temperature, first, the compounds in the ash which has low melting points, begin to melt and to show sticky property.
Next, the ash is change to slurry, and last, melt all over the ash and change to liquid phase.
When add some CaO to the ash, the melting point of the ash is more higher than the original ash. When add some Fe2O3, liquidus slag viscosity of the ash is down remarkably.
