Flue Gas Desulphurization (FGD) System Applications

100% Polymeric Epoxy Corrosion Protection for Flue Gas Desulphurization Plants

Flue Gas Desulphurization Systems are primarily used to scrub flue gas exhaust from Fossil Fired Power Plants to remove the Oxides of Sulphur present in the flue gas and render flue gas free of Oxides of Sulphur that leaves the Chimney. The Oxides of Sulphur cause extreme pollution to the environment and is also a health hazard. Hence, the Oxides of Sulphur in the flue gas should be contained before it is released to the atmosphere. Provision of FGD system is a sure shot, proven solution for this.

The FGD system mainly consists of Absorber, Stacks, Gas to Gas Heaters, Duct Work, Chemical Mixing Tanks, Slurry Tanks and Clarifiers.

Of all the problems that could beset a Flue Gas Desulphurization (FGD) system, corrosion is the one that pose challenges to system designers, manufacturers and users alike. The environment within a FGD system is a complex solids, liquids, and gases interface characterized by critical temperature fluctuations and turbulent chemical reactions. This activity is bound to take its toll on inner surfaces of ductwork, dampers, piping, pumps and other vessels coming in its path.
