“…In the present work, two types of ozone generator were used. One is a tube-type ozone generator, which consists of a grounded metal tube and a high-voltage glass tube, and the other is a plate-type one [4] with a grounded metal plate and a high-voltage ceramic plate. Figure 1 the schematic diagram of a tube-type ozone generator.…”

A new theoretical model for ozone generation from air is proposed. This model considers the dependency of the ozone dissociation rate by electron impact on the electric field strength, in addition to ozone decomposition processes through the reactions with nitrogen oxides. Assuming a stationary and uniform discharge in time and space, ozone concentrations obtained experimentally under various discharge gap widths and gas pressures are in good agreement with the analytical results. It is concluded that the discharge condition of a narrow gap and accordingly an optimized high gas pressure is one of the most effective means of efficient ozone generation for an air-fed ozone generator.

“…Basic parameters related to the excitation of particles by discharge were obtained experimentally. In the experiments we used a new plate type ozone generator [4] and a conventional tube type ozone generator [5]. In this section, we estimate some physical quantities in the discharge space from experimental results.…”

Experimental and theoretical investigations have been carried out on the ozone generation characteristics of oxygen-fed ozone generators with various discharge gap lengths. In this paper, a new theoretical model considering the dependence of ozone dissociation rate by electron impact on the electric field strength is suggested. Assuming a stationary and uniform discharge in time and space, ozone concentrations obtained experimentally under various discharge power densities and gas pressures are well explained by this model. It is concluded that the operation under a high electric field has a potential advantage in producing high-concentration ozone efficiently because of the reduction in the population density of low-energy electrons which decompose generated ozone.

“…Generally, it is known that dielectric barrier discharge, DBD, UV radiation, and electrolysis of water can be used as a method of the ozone production , especially the ozone production method by using DBD is widely adopted on the energy efficiency. Though the ozone generation efficiency has evaluated theoretically, the ozone generation efficiency of the practical ozone production system is significantly lower than the theoretically evaluated value.…”

Ozone has much attention in many industrial fields. To materialize higher ozone generation efficiency, it is necessary to elucidate the relationship between discharge characteristics for discharge electrode system and ozone generation concentration. To clarify the improvement of mechanism on the multiple needle‐to‐plane configurations, the discharge characteristics and ozone generation characteristics for a multiple needle electrode system with various needle tip distances have been investigated. In this experiment, the maximum ozone yield at needle tip interval of d = 0.5 mm was improved by the minimum discharge power, the local maximal at d = 0.5 mm of discharge volume and the same ozone generation compared with those for d = 0 mm and d = 1 mm. © 2020 Institute of Electrical Engineers of Japan.
