Under contract DE-AC21-83MC20700 from the Morgantown Energy Technology Center (METC), AMAX Extractive R&D prepared two 250-gallon lots of clean and ultra-clean coal-water slurry fuel for use in a U.S. Department of Energy program to develop coal-fueled direct-fired gas turbines for power generation. Both lots were prepared from Eastern Kentucky high volatile bituminous coal ground to pass 44 micrometers. The first lot, containing 1.95 percent ash, was prepared from coal cleaned by standard industry physical separations. Advanced chemical coal cleaning technology was used during preparation of the second lot which contained 0.40 percent ash. The grinding and cleaning operations and the rheology, composition and other properties of the two slurry fuels are described.
