Slagging occurs in boiler furnaces where ash deposits are exposed to the radiant heat of the coal flames, while fouling occurs in the boiler’s convective passes. Slagging fouling are mainly observed in coal- fired boilers. Excessive ash deposits on a coal fired boiler’s heat transfer surfaces will reduce its efficiency, and in extreme ...
