DEVELOPMENT AND CHARACTERIZATION OF SURFACE DIELECTRIC BARRIER DISCHARGE-BASED REACTOR FOR OZONE PRODUCTION

Abstract

The aim of this work is to develop an efficient plasma reactor for ozone production. The electrical characterization of the developed reactor, including the current-voltage waveform and the consumed power, is investigated at different reactor configurations (including ground-electrode width, number of electrodes, and volume of the reactor) and operating parameters (including the air flow rates and energy density). The performance of the developed reactor for ozone production is evaluated. It is observed that the consumed power increased linearly with increasing the ground-electrode width and the number of electrodes, while the reactor volume and the flow rates have no noticeable effect on the consumed power. It is also found that the increase of the plasma area by increasing the width of the ground electrode is preferable than its increase by increasing the number of electrodes. This is attributed to the decrease of the power loss in the dielectric material. In addition, an optimum size of the reactor is obtained, as the higher and the smaller ratio of the reactor volume to the plasma area are not efficient.
