Tennessee Valley Authority`s Cumberland Fossil Plant (CUF) is a Phase I facility listed under the 1990 CAA Amendments. Units 1 & 2 are two 1300 MWe coal fired units which presently bum an eastern bituminous coal containing approximately 2.8% sulfur. The Flue Gas Desulfurization (FGD) system reduces sulfur dioxide (SO{sub 2}) emissions from Units 1 and 2 by means of wet limestone - forced oxidation scrubbing. The absorber modules were provided by ABB Environmental Systems (ABBES) with balance of plant engineering, construction management, and startup provided by Raytheon Engineers and Constructors (RE&C) under a partnership arrangement with TVA. The FGD systems for Unit 1 & 2 were brought on-line October 12, 1994 and December 14, 1994, respectively. This paper will present a brief description of the overall project, the design basis, challenging problems and solutions during construction and initial startup. Specific topics will include: (1) Optimization studies underway; (2) Unique design aspects of the facility; (3) A description of the absorber and supporting systems including the limestone barge unloader, ball mill system for reagent preparation, and draft system upgrades; and (4) Experience gained in management of a large project under the unique partnership agreement.
