The experimental research on electrode configuration and discharge characteristics of pulse discharge

Wire–plate-type reactors with the pulse-induced plasma chemical process (PPCP) have been extensively investigated for flue gas cleaning such as SOX and NOX, and the electrode configuration of reactors such as the plate-to-plate spacing and the wire-to-wire spacing is directly related to the formation of discharge plasma and the utilization efficiency of discharge energy, so it is useful to study the electrode configuration in order to provide a basis for PPCP applications. In this paper, the influence of these factors such as the plate-to-plate spacing and the wire-to-wire spacing on the discharge characteristics was investigated using a positive, nanosecond pulse generator. Some experimental results were obtained and discussed. It was found that when the wire-to-wire spacing (a) and the plate-to-plate spacing (c  ) of reactors satisfied the relation below, a/c=0.4-0.6a/c=0.4-0.6, the primary streamer energy was more bigger.
