The article traces the history of flue gas desulfurization (FGD) systems in power plants in the USA following the 1990 Clean Air Act which divided boilers into Phase I (larger SO{sub 2} emitters) and Phase II units. The Clean Air Interstate Rule (CAIR) will soon require emission control on smaller boilers burning low and medium-sulfur coal. Today the systems of choice are dry FGD systems for low sulfur coals and greater than wet LSFO. (limestone forced oxidation systems) for coal with sulfur content about 2%. Demand for wet FGD coupled with tighter regulations has led to significant cost increases in LSFO. technology. 4 refs., 2 figs.
