Flue-gas desulfurization (FGD) systems based on spray drying are a relatively recent addition to the spectrum of sulfur dioxide (SO{sub 2}) control options available to utility and industrial boiler operators. Such systems appear to offer advantages over wet lime/limestone systems in a number of areas: low energy consumption, low capital cost, high reliability, and production of a dry waste that is easily handled and disposed of. These advantages have promoted rapid acceptance of dry scrubbers for applications using western low-sulfur coal, but uncertainties regarding the performance and economics of such systems for control of high-sulfur-coal emissions have slowed adoption of the technology in the Midwest and East. At Argonne National Laboratory (ANL) we have had more than eight years of operating experience with an industrial-scale dry scrubber used with a boiler firing high-sulfur (3.5%) midwestern coal. This paper describes our operating experience with that system and summarizes several research programs that have utilized it. 7 refs., 15 figs., 6 tabs.
