Water Handbook - Steam Turbine Deposition, Erosion

Oct 19, 2009 · Fouling on the convective heat transfer surface is caused by condensation of the vaporized volatile inorganic elements in fuel during combustion when the gas temperature decreases. Fouling in boilers is dependent on the type of boiler design and the fuel being fired. Fouling in a chemical recovery boiler, a coal fired boiler, and a biomass fired boiler are different in many ways.

Waste to Energy Steam Boilers

The mathematical model of a steam boiler has been developed, showing the influence of water-wall slagging and superheater fouling on the boiler performance. With traditional methods, operators often are not able to detect the critical build-up of deposits on the specific heating surfaces of the boiler. The mathematical model can be used as a boiler slagging and fouling simulator to monitor the boiler operation when the boiler heating surfaces become covered with ash deposits.

The accumulations have a composition similar to that of the dissolved solids in the boiler water. Priming and foaming are common causes of high levels of boiler water carryover. Because of the high levels of carryover often encountered, these conditions often lead to superheater tube failures as well.
