【 摘 要 】

Powerspan has conducted pilot scale testing of a multi-pollutant control technology at FirstEnergy's Burger Power Plant under a cooperative agreement with the U.S. Department of Energy. The technology, Electro-Catalytic Oxidation (ECO), simultaneously removes sulfur dioxide (SO{sub 2}), nitrogen oxides (NO{sub x}), fine particulate matter (PM{sub 2.5}) and mercury (Hg) from the flue gas of coal-fired power plants. Powerspan's ECO{reg_sign} pilot test program focused on optimization of Hg removal in a 1-MWe slipstream pilot while maintaining greater than 90% removal of NO{sub x} and 98% removal of SO{sub 2}. This Final Technical Report discusses pilot operations, installation and maintenance of the Hg SCEMS instrumentation, and performance results including component and overall removal efficiencies of SO{sub 2}, NO{sub x}, PM and Hg from the flue gas and removal of captured Hg from the co-product fertilizer stream.
