The report discusses results of a parametric evaluation of powdered activated carbon for control of mercury (Hg) emission from a municipal waste combustor (MWC) equipped with a lime spray dryer absorber/fabric filter (SD/FF). The primary test objectives were to evaluate the effect of carbon type, feed rate, and feed location on Hg emissions and control efficiency. Secondary process parameters studied included the impact of ammonia injection for nitrogen oxides control, SD outlet temperature, and SD/FF acid gas control efficiency on Hg removal. The time stability of Hg collected with ash was also studied. Conducted at the Ogden Martin Systems of Stanislaus, Inc. MWC, near Modesto, CA, testing covered 16 system operating conditions, including normal unit operation (no carbon injection) and operation without ammonia injection. Test results showed that the two primary variables affecting both Hg emission and control efficiency were carbon feed rate and uncontrolled Hg levels.
