Study of ozone generation in an atmospheric dielectric barrier discharge reactor

Ozone (O-3) generation in a dielectric barrier discharge (DBD) reactor driven by a pulsed power supply was investigated at atmospheric pressure and room temperature. An O-3 generation efficiency model is established in which discharge power, O-2 concentration, gas flow rate, and volume of the discharge space are included. Constants in the O-3 generation efficiency model were obtained by fitting the model with experiment results. O-3 concentration can be simply calculated from the energy density and initial O-2 concentration. Comparison on O-3 concentrations from calculation with references is given. (C) 2015 Elsevier B.V.
