Co-firing high sulfur coal with refuse derived fuels. Technical progress report No. 5, [October--December 1995]
Studies involving the tubular furnace are in the process of identifying the ideal experimental coal-to-refuse derived fuel(RDF) ratio for use in the AFBC system. A series of experiments with this furnace has been performed to determine the possible chemical pathway for formation of chlorinated organic compounds during the combustion of various RDF sources. Phenol and chlorine appear to be likely reactants necessary for the formation of these compounds. The main goal of these experiment is to determine the exact experimental conditions for the formation of chlorinated organic compounds, as well as methods to inhibit their development. Work on the fluidized bed combustor has involved five combustion runs, in which a combustion efficiency of greater than 96% and with a consistent CO{sub 2} concentration of approximately 13% was obtained. Modifications responsible for these improvements include the addition of the underbed fuel feed system and revision of the flue gas sampling system. New methods of determining combustion efficiency and percentage of SO{sub 2} capture using TG techniques to analyze combustion products are being developed. The current outlook using this TGA/FTIR method is very promising, since previously obscured reactions are being studied. the analysis of combustion products is revealing a more complete picture of the combustion process within the AFBC system.
