摘要：

A superposition type ozonizer has been proposed to achieve relatively high ozone concentration and high ozone generation efficiency. A high-pulsed voltage and a 60 Hz ac voltage are simultaneously applied to the same reaction volume in order to improve the ozone generation yield in a wide discharge gap. The ozone concentration of the superimposed discharge consisting of surface discharge and pulsed corona discharge was approximately two times larger than that obtained by an individual discharge. It was observed that the cross-section of the superimposed discharge extended is observed to be approximately 20% at maximum. The emission intensity of the superimposed discharge shows about two times larger than that of the individual discharge at maximum due to the increased electron temperature. The increment of local electric field in the discharge region causes the superposition effect.
