Factors involved in the selection and application of nickel-containing alloys for FGD systems are discussed. Fabrication and construction considerations with respect to the use of wallpaper lining (sheet linings), roll-bonded clad plate and solid alloys for FGD components are reviewed. North American and European experience in the utilization of these materials is described and projections for future usage are given.
Keywords: FGD systems, stainless steels, nickel alloys, under-deposit corrosion, wallpaper lining, roll-bonded clad plate, welding,
