The flue gas desulfurization (FGD) system of a coal fired electric power plant has many environments which can cause corrosion to structures, tanks, and linings. The environments can range from mildly corrosive such as the slurry feed tank which contains a limestone slurry to the very corrosive environments in the outlet duct where low pH condensate can corrode C-276 nickel alloy duct linings. Analysis showing the chemical and biological components of these environments have been collected from the Gi6son Station FGD system. A knowledge of the components causing the corrosion can be used to determine how operational changes to the FGD system or material changes can reduce the corrosion rates.
