Application of pulsed plasma for gas cleaning is gaining prominence in the recent years mainly from the energy consideration point of view. Normally, the gas treatment was carried out, at or above room temperature, by the conventional dry type corona reactor. However, this treatment is still inadequate in the removal of certain stable gases present in the exhaust/flue gas mixture. The authors report here some interesting results of treatment of such stable gases with pulsed plasma at very low ambient temperature. Also reported in the paper are, improvement in DeNO/DeNO{sub x} efficiency using unconventional wettype reactors, designed and fabricated by us, operating at different ambient temperatures. Apart from laboratory tests on simulated gas mixtures, field tests were also carried out on the exhaust gas of a 8 kW diesel engine. Further, an attempt was made to test the feasibility of helical wire as corona electrode in place of the conventional straight wire electrode. A comparative analysis of the various tests were presented together with a note on the energy consideration.
