Mitigation of ozone production by negative corona using electrode wire heating

Ozone generation is a problem associated with indoor air cleaners that utilize a corona to ionize particles. This experimentation utilized a negative corona and investigated the effect that external electrode wire heating had on the ozone production rate. Results showed that the ozone generation rate could be significantly reduced by raising the electrode surface temperature to 85 °C. Above this temperature, no further ozone reduction was observed. A linear relationship existed between ozone concentration and corona current. A parabolic relationship existed between corona current and corona voltage potential. Smaller corona wire diameters produced ozone at lower rates than larger corona wire diameters. A description of the investigation, the data collected, and a discussion of all results is included.
