Variation of Pattern and CavityDiameter of Aluminium Perforated with Single Glass Dielectric Barrier for Ozone Generation

Abstract

One of the high-voltage applications that are widely used is ozone generation. Research on ozone generations have been carried out for many years such as by using Dielectric Barrier Discharge (DBD) method to produce optimum ozone. This paper presents a variation of pattern and cavity diameter of perforated aluminium used as electrodes for ozone generation using a DBD method with single barrier glass. The result of the study showed that although 99.9% concentration of pure oxygen was used, the pattern variations and the cavity diameter of the perforated aluminium affected the ozone concentration. The highest ozone concentration was 2175.8 ppm in a chamber with electrode area of 99.58% (A2 electrode) and at 18 kV. The lowest ozone concentration was 567.5 ppm with 98.33% electrode area (A1) and at 17 kV. For stability of ozone concentration, the chamber with B2 electrode and at voltage 17 kV or 18 kV showed that the stability of ozone concentrations improved more rapidly.
