Reduction of Ozone Generation in an Electrostatic Precipitator
Atsushi KATATANI*,1, Hiroshi HOSONO*, Hikaru MURATA* and Akira MIZUNO**(Received January 7, 2008; Accepted September 29, 2008)
Electrostatic Precipitator (i.e. ESP) has recently been utilized for environmental protection of purifying road tunnel
exhaust. ESP can remove soot from automobiles by charging with corona discharge. In the meantime, corona
discharge generates ozone (O3). Nitrogen dioxide (NO2), a toxic gas element, then, increases undesirably, contrary tothe purpose of environmental protection because O3 oxidizes nitrogen monoxide (NO) contained in tunnel exhaust gas
into NO2. We examined the effect of electrode geometry and polarity of corona discharge on ozone generation. As aresult, a method has been developed to minimize ozone generation associated with corona discharge in ESPs.
