Following the success of Ferralium® 255 in the flue gas scrubbers at Gibson Station, the then-operators PSI Energy adopted the same material for future FGD absorbers.
During the construction of a new unit in 1992, Ferralium® 255 was used to build dampers for outlet ducts by butt welding 1" thick plate. The Big River Electric Corporation Sabree site also used Ferralium® 255 to line guillotine dampers in the outlet ductwork and the floor area of the outlet ducts next to the bypass re-heat duct area.
In these areas the conditions were reported as pH 1 to 2, Cl- 1000-3000ppm and a temperature of 125degF. The Ferralium® 255 has performed without problems for many years.
