INFLUENCE OF TEMPERATURE AND HUMIDITY ON NOX REMOVAL BY CORONA DISCHARGE

The object of this experimental investigation was the influence of tem perature and humidity on the efficiency of removal of NOx by a pulsed corona discharge from a mixture N-2:O-2:CO2:H2O:NO simulating a combus tion flue gas. The pulsed corona discharge was generated in a wire-to- cylinder reactor. It was found that removal of NO, was most efficient when H2O concentration corresponded with the saturated vapour pressure . In the case of the operating gas containing constant H2O concentrati on removal of NOx decreased with increasing temperature of the operati ng gas.
