Abstract
Experimental investigation of Hv short pulsed streamer discharges in dry ai r-fed ozonizers under various operating conditions are reported. Ozone conc entration, energy input and ozone production yield (efficiency) were measur ed at various voltages (14 to 37 kV), pulse repetition rates (25 to 400 pul ses per second, pps), now rates (1.5 to 3.0 l/min) and different gap spacin gs (10 to 20 mm) at a pressure of 1.01x10(5) Pa in dry air. A spiral copper wire (1 mm in diameter) made to a cylindrical configuration (18 to 38 mm i n diameter) in a concentric coaxial electrode system of various dimensions was employed. A magnetic pulse compressor provided the Hv and current pulse s. Higher voltage and higher repetition rates yielded higher concentrations of ozone at a fixed air now rate. The present investigation was extended t o assess the performance of this pulsed ozone generator using dry air under desired conditions of high concentration and high yield of ozone for indus trial applications.
