Slagging and Fouling in Coal Fired Boilers - Bright Hub ...

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.

Laser solution for power plants slowed by slagging ...

Slagging occurs when coal ash accumulates, at high temperatures, outside the tubes that carry steam inside a power plant boiler. Slagging reduces heat transfer from the flue gas to the steam tubes and decreases a plant's efficiency. In extreme cases slagging can require a boiler to be shut down while heat transfer surfaces are cleaned or repaired.
