The two-volume proceedings describe the latest research and development efforts to improve particulate control devices, while treating traditional concerns of operational cost and compliance. Overall, particulate control remains a key issue in the cost and applicability of furnace sorbent injection, spray dryers, fluidized-bed combustion, municipal solid waste, and advanced power generation processes. EPRI and EPA cosponsored the symposium, in San Diego, CA, March 20-23, 1990, featuring more than 80 presentations. Participants included approximately 350 representatives of utilities, manufacturers, universities, architect/engineering firms, and research organizations. Two parallel sessions emphasized fabric filter and electrostatic precipitator (ESP) research. Several sessions addressed high-temperature filtration as well as the impact of new sulfur dioxide control processes on baghouses and ESPs. Volume 1 contains sessions on Precipitator controls, innovative pollution control technologies, precipitator modeling, fly ash/ESP studies, ESP plate spacing, ESP rapping, ESP performance upgrading and hot-side precipitator studies.
