This paper discusses the performance and economics of advanced electrostatic stimulation of fabric filtration (AESFF), in which a high-voltage electrode is placed coaxially inside a filter bag to establish an electric field between the electrode and the bag surface. The electric field alters the dust-deposition pattern in the bag, yielding a much lower pressure drop than that in a conventional bag. Pilot-plant results show that AESFF bags can operate with a rate of pressure loss that is 70% below that for conventional bags. An economic analysis evaluated the capital, operating, and maintenance costs for electric utility plants ranging from 200 to 1000 MW. For AESFF baghouses, the capital cost was found to be 25 to 48% below that of a conventional baghouse.
