Abstract The report gives an overview of ongoing testing and evaluation of the Homer City Coal Cleaning Plant, built to enable the Homer City Power Complex to meet sulfur dioxide (SO2) emission levels mandated by the State of Pennsylvania and the U.S. Government. The plant was constructed as a result of an extensive comparative evaluation of flue gas desulfurization (FGD) and physical coal cleaning. The Homer City System, the Multistream Coal Cleaning System (MCCS), was chosen as an economical alternative to FGD. The plant contains circuits for cleaning coarse, medium, and fine coals and for recovering fine and very fine coals. The dominant type of cleaning equipment used in the plant is the dense medium cyclone. The original '93 plant' configuration was never able to clean coal to the conditions specified in the plant design. An extensive test and evaluation program was begun to identify and correct the causes of plant operating problems. After extensive pilot plant equipment tests and engineering studies were completed, recommendations were made for plant modifications necessary to correct the design and operating deficiencies of the plant. Extensive modifications were made to one of two parallel processing trains in the plant (the 'B' circuits), and a test program was initiated to evaluate these corrective measures. The modified 'B' circuits have not yet met design conditions.
