Ozone is generally produced by means of ozonizer utilized a silent discharge. The authors propose a new type ozonizer with a cylindrical rotating electrode in this paper. The ozonizer consists of two ceramic electrodes and metallic wire electrodes mounted on a rotating cylinder. The structure is capable of enhancement for silent discharge by rotation of the cylinder under the same applied voltage and we used 50Hz A.C. voltage in this experiments. It is observed that discharge current，discharge power and production efficiency of ozone are improved as compare with The no rotation of the cylinder. The maximum ozone concentration is achieved at 800rpm in rotation speed of the cylinder independent to the applied voltage. To the contrary，the maximum discharge power which correspond to ozone yield is found at the 600rpm in the rotating speed of the cylinder independent to the applied voltage too. The difference between the both maximum would be interpreted the existence of micro discharge in the gap. The obtained maximum ozone concentration is about 8.8 g/m3 and this value is two times larger than the value is two times larger than the value at the no rotation of the cylinder. The maximum production of ozone is estimated about 61g/kWh.
