Effects of Temperature and Flow Rates of Ozone Generator on the DBD by Varying Various Electrical Parameters

This study rationale a high voltage power supply which varies of (O-5) kV with the variable frequency of 50 Hz-5 kHz. The power supply is used in the dielectric barrier discharge tube for the ionization process to yield concentration of ozone.This setup points the development of small and high efficient ozone generators using corona discharge method. Ozone generation was carried out by varying parameters including voltage, frequency, flow rate and temperature to yield high concentration of ozone. The feeding gas composition greatly affected the ozone generation rate, which was increased in order of ambient air to dry air. With increase in temperature, ozone concentration is increased while ozone generation rate is enhanced. In the experiments, a maximum ozone concentration of approximately 83 ppm is obtained, the peak value of applied voltage of about 5kV and gap of electrode is 4.3mm respectively. Dry air is used as feeding gas with residence time of 10.58 sec.
