Abstract
The complications experienced by coal-fired power plants for disposing of fly ash and SO/sub 2/ emissions are discussed. The development of a waste-throwaway flue-gas desulfurization system adapting the double-alkali process (and concentrated active-alkali mode) is nearing completion for a 575-MW coal-fired power plant at Newton, Ill. The system provides closed liquid-loop operation with zero liquid-effluent outfall. Scale prevention is ensured through segregated collection from the flue gas of coal tramp components and by suppression of calcium-ion concentration in the scrubbing liquid. A review of this high-availability gas-cleaning process is given. (MCW)
