1. Full-Scale Limestone Wet Scrubbing Project at the Widows Creek Station 550-MW Unit 8 Purpose To permit investigations and development of a full-scale research and demonstration limestone wet scrubber on a high-sulfur bituminous coal boiler. To acquire pertinent data for the fullscale project at Widows Creek. 2,000,000 3. Organic Acid/Limestone Pilot Testing at the Colbert Station 1 MW To acquire pertinent data for a potential backup mode of operation at Widows Creek. 150,000 5. Lime Wet Scrubbing Pilot Testing at the Colbert Station - 1 MW To acquire pertinent data for a potential backup mode of operation at Widows Creek. To evaluate lime scrubbing and to compare the operating reliability of commercial lime to carbide lime. *Total projected cost for the entire program is estimated at $42,000,000 TABLE I 200,000 EPA-FUNDED DESULFURIZATION RESEARCH AND DEVELOPMENT PROGRAMS AT TVA Purpose To evaluate objectively and realistically with a common and uniform basis the economic and technical merits of the different methods under consideration for stack gas cleanup and, based on the findings, to point the way towards further development, demonstration, and application of the conceptual technology. To evaluate the feasibility, effectiveness, and economics of the dry limestone injection process for removal of SO2 from stack gases of coalfired power plants.
