Power analysis of ozone generator for high capacity production

Research on the power analysis of ozone generator for high capacity production has been done. We used an ozone generator with capacity of 100 grams/hour. The ozone generator was developed by providing dielectric barrier discharge (DBD) plasma reactor. DBD reactor was made of a glass tube as dielectric material and stainless-steel mesh wire as electrodes. An AC high voltage was used as a power supply. The pure oxygen and free air were used as source of gas. The produced ozone was measured at some variation of voltage, i.e. 2.5-5.7 kV with constant flowrate of 20 L/min and dissolving durration into KI solution of 2 min. The ozone concentration was measured by reacting ozone to potassium iodide (KI), as an ozone scavenger solution. The results showed that ozone capacity increase with increasing of applied voltage. The minimum and maximum capacity of ozon with pure oxygen input obtained at voltage of 2.5 kV and 3.6 kV, while with free air input obtained at voltage of 2.5 kV and 5.7 kV. Furthermore, ozone capacity of 100 gr/h with pure oxygen input obtained at power of 6.2 watt while with free air input obtained at power of 17.6 watt.
