FGD Agitator



Common Agitator Problems

Many power plants with wet FGD scrubbers have incorporated a limestone-forced-oxidation system in the absorber to ensure a fully oxidized gypsum product. Usually, several mixing agitators and air lances are located around the limestone sump area to maximize air diffusion. This has proven to be an excellent improvement in the overall FGD system effectiveness.

These plants are experiencing rapid erosion and corrosion on the tips and leading-edge surface of the agitator blades used on the mixers found in this service due to the constant use, chemicals makeup, and abrasiveness of the slurry.
