Defending boiler components against corrosive and erosive

Sep 05, 2013 · Fly ash erosion is caused by fly ash impingement on tube walls, particularly in superheaters, resulting in tube wall thinning.. Waterwall fireside corrosion typically occurs in the lower part of the boiler and sometimes is associated with the combustion process. The result is thinning of the tube wall, leading to eventual failure. Thermal fatigue most often is seen in the superheaters of coal

Reducing Solid Particle Erosion on Steam Turbine Stages

Solid Particle Erosion (SPE) damage can be found on steam turbine stages. These solid particles are caused by the exfoliation of iron oxides formed on the inner surfaces of both boiler tubes and steam pipes which are exposed to elevated temperature. They can damage both fixed and Moving Blades, as well as both outer extension ring and tip seals.
