Abstract :
The effect of corona wire surface temperature on ozone generation in an air-cleaning electrostatic precipitator is studied experimentally. The results show that significant ozone concentrations are only observed in a narrow region near downstream of the corona wire for positive coronas. From surface temperature measurements using infrared imaging, it is observed that the heat generated by corona discharge alone only increases the surface temperature of corona wire by few centigrades. Ozone generated by corona discharges can be significantly decreased by external heating of the wire.<>
