STEAM PLASMA TORCH

摘要

PURPOSE: A steam plasma torch is provided to produce an optimal processing condition by using steam as necessary plasma gas for generating flame emitted from a positive electrode part. CONSTITUTION: A positive electrode part(20) comprises a first positive electrode part and a second positive electrode part. The first positive electrode part is formed at an upper side of the negative electrode part for maintaining a gap from the upper side of the negative electrode part. The second positive electrode part is formed at the upper side of the first positive electrode part to be connected to a first positive electrode part. A steam and air supply pipe(30) supply steam and air between the negative electrode part and the positive electrode part. The negative electrode part comprises a first negative electrode part, a second negative electrode part, a third negative electrode part, and a fourth negative electrode part.
