The report gives results of a survey of the flue gas desulfurization (FGD) system retrofitted on Unit 6 of Detroit Edison Co.'s St. Clair Station. The experimental FGD system, which operated through a 2-month (October 1976-January 1977) demonstration program, utilized a limestone slurry to remove SO2 in two parallel scrubbing trains. Each train included a radial-flow venturi scrubber and a high-velocity countercurrent spray tower absorber to control Fly ash and SO2. Flue gas cleaning wastes were discharged from a reaction tank to an on-site clay-lined settling pond. Clear water was recycled from the pond to the FGD system for further use. The FGD system was designed to remove SO2 and fly ash from high sulfur eastern coal. Actual operation was on low sulfur western coal. Following the demonstration, the FGD system was shut down and modified for resumption of particulate scrubbing on low sulfur western coal in the fall of 1977. Some SO2 is removed from the flue gas during particulate removal because of the alkalinity of the collected fly ash and the limestone additive used for pH control of the scrubbing solution.
