The development of advanced coal beneficiation and utilization technologies is being sponsored by the United States Department of Energy`s Pittsburgh Energy Technology Center, to encourage the use of our abundant coal reserves. A comprehensive program is being conducted by ABB/Combustion Engineering, Inc. (ABB/CE), regarding the use of these fuels in existing utility boilers. Physical, chemical, combustion and fireside characteristics of these beneficiated products and their parent coals are being evaluated in laboratory testing. Characterization tests provide the information required to predict the performance and economic impacts of firing Beneficiated Coal-Based Fuels (BCF) in existing coal and oil utility boilers. Two utility steam generators designed for either coal or oil firing were selected for performance evaluation. The study units were selected to be representative of a large portion of the current boiler population: a 560 MW coal-designed boiler purchased in 1973; and a 600 MW oil-designed boiler purchased in 1970. Both of these units were built by ABB/CE, but the fuel related design parameters are similar to those used by other manufacturers. An Upper Freeport medium volatile bituminous (mvb) parent coal and its respective Spherical Oil Agglomeration Product (SOAP) fuel were evaluated. This paper summarizes the results of the performance analysis and describes the economic impacts that can be expected when firing BCF`s.
