Description:
The paper discusses an experimental research program to characterize corona generation from different electrode geometries in a range of conditions comparable to those found in electrostatic precipitators (ESPs). A wire-parallel plate device and a wire-cylinder device were used to monitor the spatial distribution and temporal stability of corona discharges. Corona phenomena were observed with a sensitive video camera. Conditions that were varied in the experiments included temperature, corona electrode design, corona polarity, and method of energization. Measurements of the distributions of corona current and statistical analyses permit an assessment of the impact of corona electrode design on ESP performance. The laboratory apparatus is described, and the experimental results are summarized. (Copyright (c) Journal of Electrostatics, 19 (1987) 83-99.)
