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.Typical Causes of Slagging and Fouling Problems in Boilers,Boiler slagging and fouling are among the most common causes of maintenance headaches at coal-fired power plants. Though you cannot totally eliminate the problem, following proper operation and
Slagging and deposition in coal fired boilers is a complex phenomenon. The reasons can be due to coal characteristics, operating conditions, the design of the boiler furnace, or can be a combination of any of the three with others or all.When heavy deposition or slagging starts in the boiler, the boiler operating group can contain the problem, to a large extent, by taking corrective action.New Laser Technology Helps Reduce Coal-Slagging Headaches,Specifically, slagging occurs when coal ash accumulates, at high temperatures, outside the tubes that carry steam inside a power plant boiler.
