The report incorporates the results of many studies into a manual oriented toward the collection of fly ash particles (produced by the combustion of pulverized coal) by electrostatic precipitation (ESP). It presents concepts, measurement techniques, factors influencing ESP performance, data and data analysis from a practical standpoint. Extensive use of data from full-size ESPs should familiarize the user with what to expect in actual field operation. The manual covers fundamentals of ESP, mechanical and electrical components of ESPs, factors influencing ESP performance, measurement of important parameters, advantages and disadvantages of cold-side, hot-side, and flue-gas-conditioned ESPs, safety aspects, maintenance, troubleshooting, the use of a computer model for ESP, and features of a well-equipped ESP. Studies considered in this report include those, by various individuals and organizations, on comprehensive performance evaluations of full-scale ESPs, in situ and laboratory measurement of fly ash resistivity, rapping reentrainment, evaluations of the effects of flue gas conditioning agents on ESP performance, fundamental operation of hot-side ESPs, basic laboratory experiments, and development of a mathematical model of ESP. Information from these studies can be used by power plant personnel to select, size, maintain, and troubleshoot ESPs.
