Abstract: A burner design used for thermal treatment of a surface of materials is presented. The burner includes a tubular electrode, a nozzle, a removable rod-shaped electrode which are arranged to form a discharge chamber, a means for vapor generation in the form of a reservoir provided with a flange and filled with a liquid-absorbing material, an electric arc vortex stabilization element, an element for cooling the nozzle and the electrode, and current leads. The reservoir flange is made in the form of a connection fitting and is provided with a partition having a central opening in which the tubular electrode is positioned to enable the formation of a heating element including an evaporator and a vapor superheater, both separated by the partition, the evaporator is provided with grooves for discharging vapor into a collector out of an annular recess on a surface of the vapor superheater arranged outside the reservoir.
