Slagging factor
WebSlagging is the formation of molten, partially fused or resolidified deposits on furnace walls and other surfaces exposed to radiant heat. Slagging can also extend into convective … WebSulfur contents of the coal is another important factor affecting slagging behaviour of the ash. High sulfur content increases the tendency to form slag. For this reason, all the important parameters given above should be taken into account while determining the slagging potential of a coal. 2108 Akar et al. Asian J. Chem.
