摘要：

The effect of corona wire heating on the downstream ozone concentration profiles in an air-cleaning wire-duct electrostatic precipitator is studied experimentally. The results show that ozone concentration profiles depend significantly on the applied voltage and polarity. Significant ozone concentrations are only observed in a narrow region downstream of the corona wire for positive coronas. For the corona wire surface temperature profile measurements by using a real-time IR thermoimage processing system, it is observed that the heat generated by corona discharge alone only increases the surface temperature of the corona wire by a few degrees centigrade. Ozone generated by corona discharges can be significantly decreased by the external heating of the corona wire. © 1990 IEEE
