Abstract The paper discusses economic studies of electrostatic augmentation of fabric filtration (ESFF) that indicate that the reduced rate of pressure drop rise can lead to lower capital and operating costs. (ESFF has been evaluated in the laboratory and at various pilot scales over the past several years: results of the experimental studies have always shown that electrical enhancement substantially reduced the rate of pressure drop increase during the filtration cycle.) The mechanism by which ESFF operates has been investigated, and the primary collection enhancement methods have been verified. Application of ESFF to spray dryer byproduct shows promise of an even lower pressure drop than when filtering straight fly ash. A potential drawback to ESFF appears to be the requirement for special bags in reverse-air application. Woven-in electrodes of fine wires increase the cost and perceived fragility of the bags. A new center-wire electrode ESFF has been tested in the laboratory. The center electrode has a potential for even lower pressure drop, and the system has an added advantage: standard reverse-air bags can be used.
