The main purpose of this study was to investigate the characteristics of cylindrical electrostatic precipitator with centrifugal effect in viewpoints of pressure drop and collection efficiency, experimentally. The experiment was carried out for the analysis of current-voltage, pressure drop and collection efficiency with various experimental parameters such as the applied voltage, inlet velocity, inlet size and inlet type(upper and bottom), etc. In the results, the pressure drops were estimated as 27∼54, 34∼63㎜H2O for inlet size 15㎜×3O㎜ and 30㎜×60㎜, respectively. The collection efficiencies were shown over 99% with the small inlet size(15㎜×30㎜) for the applied voltage 40㎸, inlet velocity(15∼21m/s), and 51∼89% with the large inlet size(30㎜×60㎜). Moreover, in the applied voltage 0㎸ and inlet size 15㎜×30㎜, the collection efficiency induced by centrifugal force was represented as about 35% with inlet velocity 15∼21m/s.
