Knowledge gained from a decade of operating wet lime-limestone flue-gas desulfurization (FGD) systems now allows utilities to avoid the expense and problems of an installed reheat system. Reheat consumes about 50% of the FGD energy requirements. At least 10 FGD systems are operating today with what designers call a wet stack. What's more, the approach is viable for new plants and for retrofits. For example, the upgrade of the FGD systems at Louisville Gas and Electric Co's Cane Run station included the elimination of reheat and favored wet-stack operation as a cost-effective alternative. However, designing and operating a wet stack has its own considerations which are outlined in this article.
