要約(日本語): In this paper, both the experimental data for a long time operation with and without rotation of electrode and ozone zero phenomena are presented. The effect of electrode rotation on the ozone generation process is presented. The copper rotating electrode coated with gold was used to eliminate the surface oxidant effect. During the experiments the gas temperature at the outlet of the ozonizer was measured by a digital thermometer. The ozone concentration gradually decreased with the experimental time. It seemed due to the increasing temperature and nitrogen consumption during ozone generation. When nitrogen decreased dramatically the ozone production stopped. The zero ozone concentration was kept about one hour and next 10 % nitrogen was added. After a few seconds the ozone was produced again in a mixing gas. The nitrogen consumption was increasing with the increase of rotation about twice compare with no rotation. The outlet gas temperature didn’t increase so much during experiments (about 5 degrees C). The Lisajoues figure, during zero ozone concentration will be shown in the paper. The area of it (i.e. input power) during ozone zero generation is similar value compared with when the ozone concentration of 15-25 g/m3. The demand of nitrogen during 600 rpm was about more two times compared with no rotation. A very important parameter during the ozone generation is the surface condition and nitrogen density at absorbed layer of electrode.
