The report gives results of a study of the relationships of the electrical resistivity of fly ash, its particle size, the occurrence of back corona and sparkover, and the electrical characteristics of electrostatic precipitators (ESP's). The study included laboratory measurement of the dielectric strengths and resistivity of five particle-size fractions of a fly ash sample and measurement of the current densities and voltages at which back corona and sparkover occurred for a 3-mm dust layer covering the plate of a wire-plate negative-corona discharge device. Results showed that the peak current density for the formation of back corona depended on the resistivity of the dust covering the positive electrode. Operating current densities for full-scale ESP's are discussed in relation to fly ash resistivity.
