The report describes the use of a pilot unit (consisting of two baghouses in a parallel-flow arrangement on a slipstream from an industrial pulverized-coal boiler house) to test electrostatically augmented fabric filtration (ESFF) in a reverse-air cleaning mode. ESFF is characterized by electrodes arranged about 2 cm apart around the circumference of the bag and running the length of the bag. An electric field of 2-4 kV/cm is maintained between the electrodes and perpendicular to the gas flow. Research results showed that ESFF can reduce fabric filter pressure drops and may allow reverse-air filtration at a 2 cm/s face velocity, rather than the conventional 1 cm/s. A filter bag with stainless steel electrodes woven into the fabric was developed for the reverse-air tests as part of this research. The woven-in electrode and the potential for doubling the face velocity appear to make ESFF economically attractive for commercial baghouse users.
