Survey of flue gas desulfurization systems: Will County Station, Commonwealth Edison Co. Final subtask report January--June 1977

Technical Report ·
OSTI ID:6529497
Results of a second survey of the flue gas desulfurization (FGD) system on Unit 1 of Commonwealth Edison Co.'s Will County Station are given. The FGD system, started up in February 1972, uses a limestone slurry in two parallel scrubbing trains. Each train includes a venturi scrubber, sump, and two-stage sieve tray absorber for the control of fly ash and SO/sub 2/. The flue gas cleaning wastes are stabilized with lime and collected fly ash and hauled away to an off-site disposal area. The FGD system operated as an SO/sub 2/-removal unit from February 1972 to July 1977, treating flue gas from the combustion of low sulfur western coal, high sulfur Illinois coal, and blends of both. Experimental SO/sub 2/-removal operations were concluded in July 1977. The scrubbing system remains in service removing fly ash from low sulfur western coal flue gas. Some SO/sub 2/ is removed from the flue gas during particulate-removal operations because of the alkalinity of the collected fly ash and the limestone additive used for pH control of the scrubbing solution.
