Due to its corrosion resistance to wet FGD environments, high nickel alloy clad/wallpaper steel was the structural material of choice for Phase I wet FGD systems. Electric companies were willing to pay a premium for high nickel alloy clad/wallpaper steel because they believed it would last the life of the plant with minimal maintenance.

An excellent material for wet FGD service at approximately half the cost of high nickel clad/wallpaper steel, is fiberglass-reinforced plastic (FRP) based on epoxy vinyl ester resin. With case histories dating back to 1972, FRP has become the material of choice for non-structural applications such as lime slurry piping and demister assemblies.

It is the purpose of this paper to show that FRP has been successful in structural FGD applications and should be considered by engineers who are interested in lower cost FGD systems that show potential for plant life service.
