314 Effects of Ionic Wind on Hole Type Electrostatic Precipitator

Diesel particulate matter exhausted from marine diesel engine during the combustion process cause a various human health and environment impacts. Many methods were applied to control mass concentration of particulate matter from diese l exhaust gas. Many studies of electrostatic precipitator (ESP) were reported to collect low resistive particles generated from diesel engine. This research has been developed a new hole type electrostatic precipitator (ESP) to minimi ze re-entrainment. The ionic wind was used effectively and PM was guided to the hole installed in the PM-collection electrode for re-entrainment phenomenon control. Most particle are transported into the hole by pressure difference and ionic wind. In this study, it is intended to clarify the position of the optimum hole diameter and the distance between the electrodes to PM collection efficiency.
