Abstract
The paper discusses recent developments in particulate control for coal-fired power plants. The developments are responding to a double challenge to conventional coal-fired power plant emissions control technology: (1) lower particulate emissions require more efficient control devices; and (2) lower SOx emissions achieved with low-sulfur coal combustion are coupled with poor electrostatic precipitator (ESP) performance. Possible solutions to these problems include conditioning, hot-side ESPs, and novel ESPs. Novel ESPs include the Buell Trielectrode ESP, the University of Denmark Pulse Generator/ESP, and the Cold Electrode ESP. Also under development are two-stage ESPs using novel charging sections; e.g., the Southern Research Institute Precharger, the APS High Intensity Ionizer, and the University of Tokyo Boxer Charger. As an important alternative to ESPs, baghouses have shown general success in controlling emissions from coal-fired power plants. Current baghouses are installed at the Cameo, Harrington, Holtwood, Kramer, Martin Drake, Nucla, and Sunbury power stations. When operating properly, baghouses can limit emissions to <5 mg/cu nm at pressure drops of <2 kPa. Not all baghouses have been completely successful; e.g., both high pressure drop and bag loss have been experienced at the Harrington station. (Copyright (c) 1980 AICHE.)
