Description:
The report summarizes results of advanced testing (from October 1974 through June 1978) of 30,000-35,000 acfm (10 MW equivalent) lime/limestone wet scrubbers for SO2 and particulate removal at TVA's Shawnee power station. Reliable scrubber and mist eliminator operations were demonstrated. It is shown that the mist eliminator is much easier to keep clean when the scrubber is operated under conditions giving high alkali utilization. Mathematical models were developed for predicting SO2 removal in limestone, lime, and magnesium-enhanced lime/limestone scrubbers. Forced oxidation with two scrubber loops was developed on the venturi/spray tower system with limestone, lime, and limestone/MgO slurry. Bleed stream oxidation was successful only with limestone/MgO slurry. Forced oxidation with a single scrubber loop was developed on the TCA system with limestone slurry. Other test blocks included limestone type and grind, automatic limestone feed control, Ceilcote egg-crate packing in the TCA, and flue gas emission characterization.
