The amount and nature of the ash and its behaviour at high temperatures affect the design and type of ash-handling system employed in coal-utilization plants. At high temperatures, coal ash becomes sticky (i.e., sinters) and eventually forms molten slag. The slag then becomes a hard, crystalline material upon cooling and resolidification.


The coal first goes to a preparation plant where it is washed or cleaned to remove contaminants. The cleaning removes impurities like rocks, ash, sulfur and other substances.
