No removal by ns pulsed streamer dischr|ge

In recent years a pulse width of applied voltage has a strong influence on the energy efficiency of the removal of NO. Then the ns pulse generator which can output the 5ns pulsed voltage was developed. Furthermore, the NO removal experiment was conducted using the ns pulse generator. As the results, the characteristics of the NO removal using the ns pulsed streamer discharge, the polarity of and the amplitude of applied voltage to the reactor has significant influence on the improvement of NO removal. On the other hands, it is clear that the longer length of and the smaller diameter of the coaxial discharge reactor give the higher NO removal ratio. The existence of O2 and water vapor in the gas was increased NO removal ratio. In the whole experiment, maximum energy efficiency of NO removal by ns pulsed streamer discharge reached 2.5 mol/kWh at 60% of NO removal ratio.
