The paper discusses an EPA program to develop new technologies for controlling particulate matter from stationary sources, including both electrostatically augmented fabric filtration (ESFF) and electrostatic precipitators (ESPs). The first generation ESFF system, using an electrostatic field parallel to the fabric surface, provides reductions in pressure drop to about 50% of that in conventional fabric filtration for both reverse-air and pulse-jet operation. Second generation (or Super) ESFF, utilizing an electrostatic field perpendicular to the fabric surface, provides reductions in pressure drop to 10-30%. Large diameter corona electrodes in ESPs have decreased the penetration up to a factor of 4, compared with conventional small diameter corona electrodes. Work on the multistage ESP has shown that, for high resistivity particulate matter, an ESP can be built that performs equivalent to a conventional ESP 4 to 5 times larger. E-SOX utilizes the multistage technology to free space in an existing ESP for SO2 removal of 60-90% by injecting alkaline reagents. Improved computer modeling is allowing more rapid and economical ESP designs.
