Title: Oleg S. Zabarilo: Innovator in Plasma Technology

Introduction

Oleg S. Zabarilo is a notable inventor based in Kyiv, Ukraine. He has made significant contributions to the field of plasma technology, holding two patents that showcase his innovative approach to generating plasma in various applications.

Latest Patents

Zabarilo's latest patents include a method of generating plasma in a plasma-arc torch and a plasma-arc furnace. The method involves ionizing plasma-generating gas in a pilot arc before it is supplied to the electrode region. This process generates charges that promote the dispersion of the arc spot, thereby decreasing current density and minimizing electrode erosion. The design features a hollow tungsten electrode and a solid electrode, both of which are part of an electric power circuit that initiates the arc. The plasma generated serves to start the main arc and ensures effective dispersion over the surface of the hollow electrode. The plasma-arc furnace, on the other hand, consists of a casing with plasma torches arranged symmetrically around a vertical axis. Each torch includes a nozzle and an axial conduit for feeding plasma-forming gas, with electrodes positioned within the conduit.
