FIELD: electric-arc plasma generators, applicable in power engineering for lighting-up of pulverized-coal fired boilers and in lighting of torch. SUBSTANCE: for enhancing the service life of the increase of the degree of utilization of the electrode material the internal cylindrical electrode of the plasma generator is made symmetrical relative to the plane passing through the center of the electrode perpendicularly to its axis. Due to the fact that the electrode working piece makes up less than half its length, it makes it possible to use one more cycle of plasma generator operation by turning the electrode by 180 deg. EFFECT: enhanced service life of the electrode approximately by two times. 4 cl, 5 dwg
