✦ Synopsis
In this research, a diffuse glow discharge generated by a double discharge is used to improve the efficiency of ozone generation. In this method, corona discharge occurs in the space between the cathode and the trigger electrode covered by Pyrex glass tubes, set in a groove cut on the cathode. Thus, many initial electrons are generated around the cathode.
In the present research, experiments were done in air (O 2 /N 2 mixture) at atmospheric pressure and the discharge repetition frequency was 1 Hz for all experiments. The maximum ozone concentration generated was about 150 ppm. The average ozone yield was about 400 g O 3 /kWh, much higher than the typical yield of about 100 g O 3 /kWh. The efficiency of energy transfer from energy stored in storage capacitor C 1 to the main discharge zone was about 40% to 50%.
