United States Environmental Protection Agency Air and Energy Engineering Research Laboratory Research Triangle Park, NC 27711 Research and Development EPA/600/S9-86/008 May 1986 Project Summary Proceedings: Fifth Symposium on the Transfer and Utilization of Particulate Control Technology Franklin A. Ayer The proceedings of the Fifth Sympo- sium on the Transfer and Utilization of Par- ticulate Control Technology consists of four volumes: Volume 1. Plenary, Ad- vanced Energy Applications, Economics, and Novel Concepts; Volume 2, Elec- trostatic Precipitators; Volume 3, Fabric Filters; and Volume 4, Fugitive Emissions, Dry S02, and Operation and Maintenance. EPA and EPRI cosponsored the sym- posium, held in Kansas City, MO. August 27-30, 1984. This Project Summary was developed by EPA's Air and Energy Engineering Research Laboratory, Research Triangle Park, NC, to announce key findings of research projects that an documented in four volumes of the same title (see Pro- ceedings ordering information at back). Introduction The papers in these four volumes of the proceedings were presented at the sympo- sium and provided the forum for research- ers, manufacturers, users, government agencies, educators, and students to discuss new particulate control technolo- gies and to share experiences of using ex- isting technologies. The major particulate control technolo- gies-electrostatic precipitators (ESPs) and fabric filters (FFs) — were the primary con- cern of the symposium. These technolo- gies were discussed from perspectives of economics, new technical advancements in science and engineering, fundamentals, applications, and operation and main- tenance. Additional topic areas dealt with dry S02 removal, fugitive emissions, and novel concepts. The symposium was conducted as a series of parallel sessions, each contain- ing four to six related papers. The sessions were scheduled, however, to avoid any conflict that might be caused by simul- taneous sessions dealing with the same topic. The papers, therefore, have been divided into four volumes. Each volume contains a set of related session topics so as to provide reasonably ready access to a unified technology area. Volume 1 Papers Volume 1 describes various aspects of particulate control. The plenary session was devoted to the regulatory framework for future technology needs and the im- pact of particulate control requirements on utilities, the iron and steel industry, and large and small manufacturers. Economic comparisons of the costs of the particu- late control devices, computerized process control of ESPs, levelized annual revenue requirements for electric utilities and microcomputer models, and the impact of proposed acid rain legislation on control equipment were presented and discussed. Novel particulate control technologies covered particle charging with an electron beam precharger and by evaporating charged water droplets as well as the roles of electrostatic forces in high velocity par- ticle collection devices, hot gas fabric filtration, and the prediction of plume opacity from stationary sources. ------- Session 1: Plenary Session The Regulatory Framework for Future Particulate Technology Needs Sheldon Meyers, U.S. EPA The Impact of Coming Par- ticulate Control Requirements on the Utility Industry George T.

Various aspects of plume opacity control, retrofitting ap- plications, pulse energization and rigid electrodes were discussed.
