The report summarizes work on electrical stimulation of fabric filtration (ESFF) with the major objectives of defining the role of some primary variables and understanding the mechanisms of electrostatic enhancement. It was concluded that the magnitude of particle charge has a strong effect on ESFF performance by causing shifts in dust deposition from a uniform pattern to a selective deposition along the electrodes in the bag and toward the bottom half of the bag. The drastic reduction in pressure drop indicated that some form of precharging would be cost effective. Programmed changes in electrical field strength to coincide with the cleaning cycle or the use of ac rather than dc fields showed no significant promise of improved bag cleaning. 'Printed' electrodes could be as effective as wire electrodes and would probably cost less to incorporate in the bag if they could be made to hold up under bag flexing at elevated temperatures.
