Abstract
The paper gives results of a pilot plant study of electrostatically augmented fabric filtration (ESFF) to transfer laboratory technology to the field environment. (Note: Electrostatic fields at the fabric surface of fabric dust collectors have been observed in the laboratory to reduce the flow resistance of the collected dust and to reduce the dust penetration into the fabric.) Conclusions include: (1) using an electric field parallel to the fabric surface, without particle charging, to enhance fabric filter operation is operable at pilot scale (the pilot plant operated on flue gas from an industrial boiler); (2) the electrical hardware developed for the pulse-cleaned baghouse is workable and durable in the operating environment and has potential for commercial use; (3) at any given face velocity, the ESFF baghouse has a reduced residual pressure drop and a reduced rate of pressure drop increase when compared with a conventional fabric filter; (4) the pulse-cleaned ESFF baghouse could be operated in a stable fashion at filter face velocities up to about twice that at which the conventional baghouse was stable; and (5) the pilot unit results are consistent with dust cake expansion and lowered porosity due to a tendency to form dendritic structures as the dust cake collects.
