Gas Temperature of Both Electrodes Cooling Tubular Type Ozonizer

The gas temperature in ozonizer affects the characteristics of the ozone generation greatly. We examined the gas temperature at outlet of discharge space theoretically and experimentally using the tubular type ozonizer by which both electrodes are cooled. It is clear that the gas temperature obtained from the experiments is about 60% of one from calculation, and the difference of gas temperature between experiment and calculation increases as the gas pressure and the discharge gap length are larger. It is considered that these differences are due to the non-homogeneity of discharge power in gap. We obtain the experimental equation of gas temperature as the function of gap length, gas pressure, discharge power density and cooling water temperature.
