Abstract (en)
[origin: EP0465140A2] An arc-heated plasma lance which is not exposed to clogging by superheat hydrocarbon gases is characterized by a shorter downward electrode and a generally shorter length of the upward and downward electrodes combination, with a flaring out electrode end at the outlet port for receiving the arc roots of the downward electrode, thereby to provide increased efficiency and generate radiant energy, as well as insuring non-clogging operation. <IMAGE>
