“…In the region of high voltage, more electric power is consumed at the longer gap. This result could be explained by an empirical formula of electric power consumed [15]. The slope of the curve, which shows the relationship between the consumed power obtained from the formula, P , and gap length d, varies from minus to plus by increasing the applied voltage in a short gap.…”

“…The discharge voltage V * (that is to say, the voltage drop across the gap during the discharge) can be obtained from an intersection of the horizontal axis and the curve because the electric charge on the barrier is zero at V = V * [12][13][14][15]. The discharge voltage is presented as a function of gap length, as shown in figure 3.…”

“…Capacitances of the dielectric barrier and the gap space can be obtained from the slopes of V -Q Lissajours' figure in figure 2 [12,14,15]. Since the way A-B corresponds to the variation before the discharge, the series connected capacitances C B and C G can be obtained from the slope of the line A-B.…”

In this paper we describe the dependence of NO/NO x removal on gap length by a multipoint-type dielectric barrier discharge in a region of short gap length. A 20 kHz sinusoidal voltage of 3-6 kV P P was used to generate the barrier discharge for removal of NO and NO x from a simulated flue gas. The gap length was varied in the range 0.05-0.5 mm. The multipoint-to-plane geometry was used as the electrode in order to lower the operating voltage. Using the V -Q Lissajours' method, the discharge voltage across the gap was measured during the discharge. The result shows that the average value of the reduced electric field increases up to 200 kV cm −1 by shortening the gap. It has been clarified from the spectroscopic measurement that the electron temperature in the discharge plasma becomes higher by shortening the gap. The NO removal, however, decreases with narrowing of the gap. This fact is considered to be caused by the fact that ozone generation decreases with reduced electric field in a region of high E/n.

“…More recently, major fresh water and waste water treatment facilities using ozone water treatment methods have been constructed throughout the world. Additionally, new industrial applications of ozone such as wastewater treatment, exhaust gas treatment, odor elimination and semiconductor manufacturing have been studied recently [27][28][29][30][31][32][33][34][35]. However these new ozone applications demand high concentration of ozone, it was become possible for DBD to produce high concentration (100 to 300 g/m 3 ) of ozone due to the improvement of dielectric materials and electrodes cooling function, and development of ultra-short gap electrodes [27]- [35].…”

This study is devoted to an investigation of the energy consumption and byproduct generation of the nonthermal plasma-chemical NO-reduction process. Nitrogen gas with a 200 ppm NO impurity has been processed at a pressure of 1.3 atm in a silent discharge reactor with a gap spacing of 50 µm. Detailed measurements of NO, NO 2 and N 2 O concentrations at the reactor outlet were carried out and analysed by means of the created model. On the basis of the proposed three-collision reaction mechanism of N 2 O generation the byproduct-suppression effect has been predicted and experimentally confirmed. An extremely low energy consumption (less than 150 eV per molecule) for NO reduction by the discharge nonthermal plasma has been attained.
