“…Therefore, the maximum power is limited to the value of pulse frequency [42]. As shown in the figure, for the same input power, the NOx removal efficiency is almost higher at the lower frequencies [41,43]. However, at the very low frequencies such as 13.4 kHz, high input power and, as a result, high removal efficiency cannot be achieved at the studied range of applied voltages.…”

In this paper, a comprehensive study of a DBD reactor is conducted to investigate the optimum operating conditions of the reactor for NOx treatment. For each parameter, the objective is to find the maximum NOx removal efficiency with the minimum consumed power. Different effective parameters of the reactor i.e. electrode length and diameter, electrode and dielectric materials as well as parameters of power generator, i.e. voltage and frequency, are investigated. The results show that for this configuration, the electrode with 20 cm length and 10 mm diameter has the best performance. Aluminum as the inside electrode material and quartz as the dielectric material are selected. Furthermore, the optimum value for the pulse frequency is 16.6 kHz. For the mentioned optimum conditions, the NOx removal efficiency achieved is equal to almost 82% at the input power of 486 W. Furthermore, the highest achieved NOx removal is almost 92% at the input power of 864 W. The results of this paper can be used to reduce the energy consumption of NTP systems to acceptable levels.

“…The reaction rates of (12) and (13) were greater than the reaction rate for (9), so with the addition of oxygen, the destruction the nitrous oxide was faster than its generation, which led to the observed decrease in concentration. Figures 5 and 6 illustrate that before the addition of oxygen, the reaction of NO was a reduction reaction and produced N 2 O and N 2 , with very little NO 2 .…”

The effect of O 2 and H 2 O vapor on the Nitric oxide (NO) removal rate, the NO 2 generation rate and the discharge characteristics were investigated using the dielectric barrier discharge (DBD) reactor at 1 atm pressure and at room temperature (20°). The results showed that the O 2 present in the flue gas always hampered the removal of NO and the generation of N 2 O, but that the O 2 could enhance the generation of NO 2 in the NO/N 2 / O 2 mixtures. Furthermore, with the increase of oxygen, the average discharge current gradually decreases in the reactor. The H 2 O present in N 2 /NO hindered the removal of NO and the generation of NO 2 but had no impact on the average discharge current in the reactor in the NO/N 2 /H 2 O mixtures in which the HNO 2 and HNO 3 was detected. The energy efficiency of the DBD used to remove the NO from the flue gas was also estimated.

“…In recent years, the electric discharge technologies for pollutant control received more attention. These electric discharge processes mainly involve dielectric barrier discharge [1,2], surface discharges [3], partial discharges in a ferroelectric pellet layer [4] and pulsed corona discharge [5,6]. Especially the pulsed corona discharge process, owing to its advantages such as simultaneous removal of SO 2 , NO x and VOCs, simple operation process, small installation area, etc, represents a very attractive alternative to the conventional treatment methods of flue gas like flue gas desulphurization (FGD) and selective catalytic reduction (SCR).…”

Pulsed discharge deNO x /deSO 2 process has been studied for over 20 years, but how to achieve higher removal rate at lower cost remains one of the crucial issues for realization of its industrial application. This paper presents a novel deNO x /deSO 2 process that combines a wire-plate type pulsed discharge reactor and a corona radical shower. Our aim is to increase the deNO x /deSO 2 rate of wire-plate type reactor by enhancing the generation of radicals with pulsed corona radical shower. Effect of a nozzle electrode on the production of OH radical was studied by emissive spectrum, and deNO x /deSO 2 experiments using a wire-plate reactor with pulsed corona radical shower were conducted. The experimental results demonstrated that corona radical shower could enhance the production of radicals and the deNO x /SO 2 performance of a wire-plate reactor. This study will play a positive role in the industrial application of wire-plate pulsed discharge deNO x / deSO 2 reactor.
