GPU Genco, the New York State Electric and Gas Corporation (NYSEG), Penn State University and the Homer City Coal Processing Corporation are conducting characterization and formulation tests to determine the suitability of using minus 325 mesh coal waste fines as a low solids coal water slurry (CWS) co-firing fuel. The fine coal is contained in a centrifuge effluent stream at the recently modified Homer City Coal Preparation Plant. Recovering, thickening and then co-firing this material with pulverized coal is one means of alleviating a disposal problem and increasing the Btu recovery for the adjacent power plant. The project team is currently proceeding with the design of a pilot scale system to formulate the effluent into a satisfactory co-firing fuel on a continuous basis for combustion testing at Seward Station. The ultimate goal is to burn the fuel at the pulverized coal units at the Homer City Generating Station. This paper presents the success to date of the slurry characterization and pilot scale design work. In addition, the paper will update GPU Genco`s current status for the low solids coal water slurry co-firing technology and will outline the company`s future plans for the technology.
