Abstract

Two models of plasma generator/reaction chamber with divergent channel have been used in the laboratory testing. The arc was magnetically driven between co-axial electrodes, which resulted in fast arc expansion and a thermal tail formation called the dispersed plasma. These plasma reactors have been successfully used in thermal destruction of chlorinated wastes. In this paper the plasma generators design principle and test results aimed to establish the arc discharge stability criteria are presented.
