Show t COAL SLURRIES AS ALTERNATE FUELS FOR OIL-DESIGNED BOILERS Y. S. Pan, G. T. Bellas, R. B. Snedden and J. I. Joubert U.S. Department of Energy Pittsburgh Energy Technology Center Pittsburgh, PA 15236 ABSTRACT Several combustion test programs have been performed at the Pittsburgh Energy Technology Center (PETC) of the U.S. Department of Energy (DOE) to evaluate alternate fuels in oil-designed boilers. The overall objective is to develop retrofit technology for existing oil-fired boilers to conserve petroleum fuel. The alternate fuels investigated at PETC include coal-liquid mixtures, such as coal-oil, coal-water, and coal-methanol. In this paper, the hardware developed to permit utilization of coal slurries as liquid fuels in oil-designed boilers is described, and selected coal-slurry combustion test results are presented.
