Abstract
Energy efficient generation of ozone is very important because ozone is being used increasingly in a wide range of industrial applications. In this study, ultra-short duration pulsed streamer discharges with a duration of 5 ns hava been used to produce ozone in a wire-to-cylinder electrode reactor. The triaxial Blumlein configuration is used for the nano-seconds pulsed generator. Ozone concentration and ozone production yield were measured at various applied voltages (50 to 70 kV), and pulse repetitions (10 to 60 pps) at atomospheric pressure in oxygen and air. The experimental results showed that the ozone concentration (g/m3) increased with increasing applied pulse voltage and pulse repetition rate. Higher ozone concentrations were obtained in the oxygen-fed ozonizer than in the air-fed ozonizer. The ozone production yield (g/kWh) was high at low ozone concentration, and higher ozone yield was obtained with lower applied voltages. Characterization maps of ozonizers based on different discharge methods (nano-seconds pulsed discharge, DBD, DBD with narrow-gap, surface discharge, pulsed corona discharge, DC corona, superimposed discharge methods and a commercial ozonizer) were presented with oxygenfed and air-fed cases. A nano-seconds pulsed discharge showed the highest ozone yield in the characterization maps for both the oxygen-fed and air-fed cases, where the highest ozone yield were 544 and 239 g/kWh in the oxygen-fed and air-fed cases, respectively.
