The overall objectives of this study were to perform pilot plant tests to evaluate techniques that can be used to reduce mercury reemissions from wet limestone scrubbers in coal-fired power plants. A pilot-scale (0.01 MW) wet limestone FGD system was designed, constructed, and debugged for the purpose of conducting mercury reemission research. The scrubber used limestone slurry as the reagent to absorb sulfur dioxide and mercury from flue gas generated from a furnace. Usually, natural gas was used as the fuel in the furnace to provide better control of flue gas conditions. An Illinois coal, Galatia, was also burned in the furnace to verify the results from natural gas tests.
