Evaluation of Corrosion-Resistant Alloys for Wet Electrostatic Precipitator
We found suitable corrosion-resistant alloys for a wet electrostatic precipitator (WESP) equipped with an intermittent washing function used in power plants that use fuel with a high sulfur content. Using seven types of corrosion-resistant alloys selected in advance, tests were run to compare the four forms of corrosion that occur within the WESP. N06022 or N10276 produced better results when pH was lower than 0.5. In the 0.5 pH to 1.0 pH range, S32053 was found to be the ideal material from the viewpoint of both corrosion resistance and cost. By capitalizing on our wealth of design technologies and know-ledge of materials, we can provide optimum systems for the corrosive environment within the WESP.
