An Experimental Study for Designing Electrostatic Precipitator: Focused on Collection Efficiency Variation per Area and corona Power

The Electrostatic Precipitator is one of the most favorable device of particulate control systems because of the relatively higher collection efficiency and easier operation/maintenance. However, it requires very high initial coat especially for discharging electrodes and collecting plates. In dealing with such problems, development of optimum design can be one of the solutions. In this study, a bench-scale electrostatic precipitator was operated in terms of collection area and corona power, and its performances were analyzed focusing on collection efficiency. A result of this study, a more advanced approach for designing cost-effective precipitator by promoting corona power at a minimized collection area was proposed.
