For a lime FGD system, a lime slaker processing pebble lime is required in place of the limestone wet ball mill. To facilitate the disposal of the solid waste, or to produce a saleable product in the form of high quality gypsum, a forced oxidation system may be utilized to oxidize the main reaction product, calcium sulfite, to gypsum.
