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. Even though both effects heat transfer, fouling happens in the convection heat transfer surface in the boiler and
