Corrosion of Alloy 2205 in Wet Flue Gas Desulfurization Systems Rob Grabarczyk, We Energies Significant pitting was discovered in two newly commissioned wet flue gas desulfurization absorber vessels. The vessels are constructed of solid duplex alloy 2205 with both vessels accumulating less than six months of operation when the pitting was discovered. This presentation provides a description of the pitting and We Energies efforts to determine the cause and potential solutions to ensure reliable operation of the system.

Applying Proper Cycle Chemistry Programs to a newly constructed Coal Fired Supercritical Unit Rob Grabarczyk, We Energies This paper and discussion chronicles the experience of start up and commissioning a new 600 MW coal fired supercritical boiler. In starting up a new unit, many challenges are encountered that are not typically seen in units with a longer operating history. Insight is provided into the decisions to start the unit using AVT-R and progress to AVT-O and ultimately Oxygenated Treatment.
