Strategies are being developed at Penn Sate to produce ultralow emissions when firing coal-based fuel, i.e., micronized coal and coal-water slurry fuel (CWSF), in industrial boilers. The research is being conducted at 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). Specific activities are identifying/developing a low-temperature NO{sub x} reduction catalyst, studying the occurrence of nitrogen in coal and the fundamental mechanisms of NO{sub x} production, characterizing air toxic emissions, investigating the use of BioLime{trademark} for simultaneous SO{sub 2}/NO{sub x} reduction, and evaluating a ceramic filter for fine particulate control. Results from trace element and polynuclear aromatic hydrocarbon emissions testing when firing coal-based fuels are reported elsewhere in these proceedings. This paper discusses the preliminary results obtained using ceramic membrane filters for fine particulate removal when firing micronized coal in a package boiler.
