Strategies are being developed at Penn State to produce ultralow emissions when firing coal-based fuels, i.e., micronized coal and coal-water slurry fuel (CWSF), in industrial boilers. The work is being conducted on the bench, pilot, and demonstration scale, and the emissions being addressed are SO{sub 2}, NO{sub x}, fine particulate matter (PM{sub 10} and PM{sub 2.5}), and air toxics (trace elements and volatile organic compounds). Technical issues related to trace element emissions that are to be addressed include: (1) the effectiveness of coal cleaning; (2) the effect of fuel form (CWSF and pulverized coal); (3) partitioning between the solid and vapor phases; (4) the effect of boiler size; (5) penetration through particulate control devices; (6) the effect of sootblowing; and (7) mercury speciation. This paper discusses the results of preliminary work to determine trace element emissions when firing a raw and cleaned pulverized coal in a pilot-scale combustor. A companion paper, which follows in the proceedings, gives the results of polynuclear aromatic hydrocarbon (PAH) emissions testing in the pilot-scale combustor and in a small industrial boiler. Results from fine particulate testing is found elsewhere in the proceedings.
