Abstract: The article discusses ways to increase the efficiency of ozone production in a coaxial chamber using a pulsed corona discharge. The effect of the discharge gap and the diameter of the potential electrode on the energy efficiency of ozone production using a pulsed corona discharge of negative polarity with duration of 40 ns and voltage of about 100 kV was investigated. It is shown that with an increase in the discharge gap, the productivity of the installation decreases, and the energy efficiency increases. The optimal diameter of the potential electrode has a value of about 0.64 mm. This information will be useful in the development of highly efficient ozonators and in optimizing the parameters of plasma-chemical reactors for air purification by electro-discharge methods.

Keywords: pulsed corona discharge, ozone, non-equilibrium plasma, ozonator.
