Comparison of electrical characteristics of barbed-plate and wire-plate precipitators

摘要

Differences in electrical characteristics of barbed plate-to-plate and wire-plate precipitators are presented in terms of measured current-voltage curves and spatial distributions of current at the collection plate. Data are obtained in a 61.0 cm by 61.0 cm by 15.2 cm laboratory precipitator operating at Reynolds and electrohydrodynamic numbers typical of industrial precipitators. Results show that a barbed plate-to-plate precipitator produces more uniform distributions of current along the collector plates than exist in a conventional wire-plate precipitator.
