Heat Transfer Surface Fouling in Boilers

Fouling in boilers is dependent on the type of boiler design and the fuel being fired. The main factor that leads to fouling in a coal fired boiler is the increase in percentage of the low melting constituents. Fouling in boiler heat transfer area is different from slagging.: Dr V T SathyanathanMechanisms of Slagging and Fouling and Fouling Based on different mechanisms involved in ash deposit on the heat surface, two general types of ash deposition have been defined as slagging and fouling. Slagging is the formation of molten or partially fused deposits on furnace walls or

What is Fouling? - Definition from Corrosionpedia

Fouling is the settlement, and sometimes the growth, of undesired materials on solid surfaces in a way that reduces the efficiency of the affected part. Fouling may be caused by either the operating environment or by one of the equipment's processes. It deteriorates
