<p>The invention relates to a burner design and can be used for thermal treatment of a surface of materials. The burner comprises a tubular electrode, a nozzle, a removable rod-shaped electrode which are arranged to form a discharge chamber a means for vapour generation in the form of a reservoir provided with a flange and filled with a liquid-absorbing material, a means for electric are vortex stabilization, a means 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 that consists of an evaporator and a vapour superheater, both being separated by the partition, the evaporator is provided with grooves for discharging vapour into a collector out of an annular recess on a surface of the vapour superheater arranged outside the reservoir, and also with a capillmy-porm shell made of a material of high thermal conductivity and arranged to allow its one side to contact with the evaporator surface and its other side to contact with the liquid-absorbing material of low thermal conductivity. The invention provides a simplification of the burner design and an improvement in performance by recovering large heat flows having an high heat supply density with a low thermal resistance.</p> |
