Description:
The paper gives an overview of a number of key projects in the Environmental Protection Agency's (EPA's) particulate research and development program having applicability to industry. For electrostatic precipitators (ESPs), it gives results of work on large-diameter discharge electrodes which provide a decrease in penetration of up to a factor of 4 when compared to conventional small-diameter electrodes. It also discusses the multistage ESP which provides a collection efficiency that would require a collecting plate area 4 or 5 times larger with conventional ESP technology. E-SOX technology utilizes the multistage concept to free up space in the ESP for SO2 removals of up to 90%. Electrostatically augmented fabric filtration provides a reduction in pressure drop of about 50%, compared to conventional fabric filtration. Wind tunnel modeling of windbreaks for material storage piles indicates a potential for providing engineering design data that would allow significant emission reduction caused by wind erosion.
