Abstract :
Discharge and ozone generation characteristics of a ferroelectric-ball and mica-sheet double barrier were investigated to study fundamentals of the barrier discharges and find out the optimal condition for efficient control of the pollutant gases. Five kinds of ferroelectric-balls, of which the dielectric constants are 33, 150, 660, 1500 and 1000, were investigated in atmosphere with various pulse frequencies of 0.2~4.0 kHz. It is found that the double barrier has better discharge characteristics for ozone generation than those of a ferroelectric-ball single barrier and that ozone generation is greatly influenced by the dielectric constant of the ferroelectric-ball barrier and applied pulse frequency. As a result, there is an optimum condition of the dielectric constant and the applied pulse frequency to generate ozone effectively which are about Er=660 and frequencies higher than 4 kHz at the given experimental conditions
