Pulsed Plasma Gliding-Arc Discharges With Water Spray

Pulsed gliding-arc discharge (PGD) (25 kV, 18 W, and 170 Hz) was produced between two divergent electrodes using an ignition coil in place of the conventional ac transformer. The time courses of pH, conductivity, and the formation of hydrogen peroxide in pure water with a variety of different carrier gases were determined in the PGD and ac-gliding (ACG)-arc reactors. The energy yield for the destruction of an organic blue dye in the PGD reactor is approximately 150 times higher than in the ACG-arc reactor with Ar carrier, and the energy yields for the formation of hydrogen peroxide are 270 and 260 times higher in the PGD reactor than in the ACG-arc reactor with Ar and 02 carrier gases, respectively.
