Flue-gas desulfurization (FGD) systems based on spray drying 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. 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. This paper summarizes 4 years, operating and research experience with that system and describes the current research program, which includes an indepth characterization of an industrial scale dry scrubber with 3.5% sulfur coal.
