Abstract
Discharge ozone production depends on different quantities and the effect of one quantity on this process cannot be separated from the effects of other quantities. Thus the temperature influences the reaction rates of individual reactions involved in ozone generation and destruction, the thermodynamic properties, and the density of the feeding gas. The density of the feeding gas influences the reduced electric field, which affects ionization of the gas, production of electrons and consequently the electrical parameters of the discharge. Taking into account these considerations we investigated the effect of temperature and various arrangements of the input and output of the feeding gas to and from the discharge chamber together with related changes of electrical parameters of the surface dielectric barrier discharge on its ozone production for the temperatures in which commercial ozone generators function. We found that if the temperature of air at the output from the discharge chamber is increased from 15.0 ± 0.5 to 25.0 ± 0.5 °C, the discharge ozone production and peak discharge voltage decrease. Both the discharge ozone production and the peak discharge voltage are also affected by the way in which the feeding air is supplied to and leaves the discharge chamber. We also showed that for all ways in which the feeding air is supplied to and leaves the discharge chamber the discharge nitrogen dioxide production follows the same trends as discharge ozone production.
