Influence of temperature and humidity on NO x removal by corona discharge

The object of this experimental investigation was the influence of temperature and humidity on the efficiency of removal of NO _x by a pulsed corona discharge from a mixture N₂ : O₂ : CO₂ : H₂O : NO simulating a combustion flue gas. The pulsed corona discharge was generated in a wire-to-cylinder reactor. It was found that removal of NO _x was most efficient when H₂O concentration corresponded with the saturated vapour pressure. In the case of the operating gas containing constant H₂O concentration removal of NO _x decreased with increasing temperature of the operating gas. Dedicated to Prof. Jan Janča on the occasion of his 60^th birthday. This work is devoted to the 60^th birthday of Professor Jan Janca, our good colleague, merited teacher, researcher and famous physicist, discussion with whom stimulated this and other our work during years.
