AshProSM was applied to a 512-MW tangentially-fired boiler at Wisconsin Power & Light's Columbia Energy Center to evaluate the localized slagging on furnace walls and fouling in convective pass. The predicted boiler ash deposition pattern is reasonably consistent with that observed on the furnace walls and super heater division panels.

Heat Transfer Surface Fouling in Boilers - Bright Hub Engineering

2009/10/19 · 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 …
