Slagging and Fouling in Coal Fired Boilers

Coal fired boilers experience deposition and slagging depending upon the ash characteristics of ash in the coal being fired. In many cases the operating parameters also play a major role. The molten or partial melting pasty ash deposits in radiant heat transfer surface like boiler furnace is termed as slagging. The sintered ash deposit in the convection region in boiler is called fouling.
