Application of gas discharge with liquid electrolytic cathode to create flow of steam-water plasma

Abstract

© 2020 Published under licence by IOP Publishing Ltd. A gas discharge with flowing liquid electrolyte cathode was experimentally investigated under combustion conditions inside an extended chamber with walls made of refractory material. The copper anode was located above the cathode at a distance of 20 cm. The length of the output channel was 50 cm. Heavily diluted aqueous solutions of sodium chloride were used as the electrolyte. The mass velocity of the electrolyte ranged from 8-16 g/s. A three-phase two-half-wave rectifier with voltage at the output of 2100 V served as a power source. The discharge burned stably without a ballast resistor. A plasma flow with mass velocity of 1.0-1.7 g/s in the power range of 25-30 kW was obtained. The total heat loss through electrodes did not exceed 30% of power consumption.
