Abstract
The paper details an investigation into the corrosion experienced by two electrostatic precipitators serving emissions from a Portland cement plant. Practical details of the problems encountered and of the resolution of the problems are discussed. The cause of corrosion was found to be acid dewpoint corrosion. The use of low-sulfur coal, higher operating temperatures, and improved insulation were investigated. Structural renovations and other equipment improvements are recommended.
