In a two-phased project, Graycor Industrial installed a new selective catalytic reduction (SCR) on Alliant Energy’s Unit 5 located at its Edgewater Generating Station in Sheboygan, Wisconsin. Phase I included relocation of the precipitator inlet duct and installation of micropiles for future structural steel installation to support the new SCR. Phase II, which is currently under way and will reach completion at the end of 2012, entails installation of the SCR for the 430-megawatt Unit 5. During Phase II, the existing ductwork air flow was rerouted into the new SCR box. Two outages were completed in Phase II, one in 2011 and another in 2012.
