In recent years, a number of technologies for flue gases desulfurization (FGD) have been developed, such as wet or dry FGD processes. [1] [2][3][4][5] The lime/ limestone process is the most ...

Nowadays more than 90 % of all modern FGD plants worldwide are using this kind of agitator-lance-system. One other big issue in the flue gas desulfurization process is the high abrasion on the impeller blades forced by high solid concentration and flue ash. Extending the life-time, was the goal for developing the EKATO Wingjet impeller.

Flue Gas Desulfurization Absorbers. We understand the need to preserve the life of your plant's FGD system. Within any FGD absorber is a harsh environment: a mixture of acidic gasses, high temperatures and varying velocities of flue gasses and slurry sprays. These are then characterized by constant abrasion of limestone slurry and pH swings.

The global FGD systems market is projected to grow from USD 19.3 billion in 2021 to USD 24.9 billion by 2026, at a CAGR of 5.2% from 2021 to 2026. The FGD systems market has shown a positive ...

Reagent Preparation System. The reagent preparation system of flue gas desulfurization (FGD) includes a Wet ball mill and cyclone classifiers which produce a finely ground limestone slurry at 90% solids passing through 325 mesh. One mill slurry tank and one slurry pump is supplied for one wet ball mill. The mill slurry pump will send …

assumed that FGD conditions would be normal and that carbon or low alloy steel would offer the suitable functionality. Although when the first FGD scrubbers started functioning, intense corrosion problems occurred. The FGD systems have been upgraded over the past 35 years from coated carbon steel to clad stainless steels and high nickel alloys.
