Pulse and power three-phase plasma generators, possible applications

Summary form only given. It is well known that plasma pulse generators are used widely in scientific investigations and in industrial technologies. The main spheres of plasma generator application are enumerated in this work. Simplified construction of pulse plasma generators with a coaxial electrode system is presented. Typical oscillograms of the discharge current, voltage drop on the arc, the pressure in the discharge chamber, power chart of the arc and other physical processes in the arcs of the pulse plasma generators are shown. Three-phase single chamber plasma generators are considered to be quite perspective for solving this problems. Two types of plasma generators are analyzed: the first type is intended for inert gases, nitrogen and hydrogen heating, with electrodes made from composite materials on the basis of tungsten. The second type of generators is to be used with air and other oxidizing media. Plasma generators with the power of (60-500) kW with pipe copper electrodes are analyzed. The new possible area of pulse plasma generator applications-the destruction of toxic and industrial waste is stated.
