Seminole electric FGD study reveals corrosion mechanisms, duct material performance

To properly evaluate the corrosion resistance of the materials used to fabricate the flue gas desulfurization (FGD) components, a testing scheme that systematically exposes material samples to the many environments representing areas of varying corrosivity is ideal. Field testing of this type was co...

Description
Summary:To properly evaluate the corrosion resistance of the materials used to fabricate the flue gas desulfurization (FGD) components, a testing scheme that systematically exposes material samples to the many environments representing areas of varying corrosivity is ideal. Field testing of this type was conducted at the Seminole Generating Station which consists of two 650-MW coal-fired electric generating units that typically burn western Kentucky and eastern Illinois sub-bituminous coal with a sulfur content up to 3% and a 0.2 to 3% chloride content. The results of this study is presented and discussed.
