Abstract
In this paper, a dielectric barrier discharge cylindrical reactor has been analyzed in order to increase the efficiency of nitrogen oxide (NOx )removal from the simulated gas under the room temperature. The effects of electrode shape as well as electrode diameter and electrode length are investigated in the nonthermal plasma reactor. Two different electrode configurations (rod and screw thread electrodes) are examined. The experimental result shows that for the rod electrode, NOx removal efficiency is enhanced by increasing the electrode diameter. However, the screw thread electrode is more effective in decreasing NOx concentration. Finally, the results showed that the average input power requirement for NOx removal can be reduced almost 14% using a 1-mm screw thread electrode instead of a rod electrode.
