<P>PROBLEM TO BE SOLVED: To simplify and miniaturize a sub-torch as a whole by reducing the number of components of the sub-torch, and to increase plasma output by enhancing the direct-advancing property and stability of plasma and plasma flame. <P>SOLUTION: A composite torch type plasma generator comprises a main torch 1 and the sub-torches 2, the main torch and the sub-torches, each of which has a cathode, an anode and a plasma gas supply means. In the plasma generator, several sub-torches 2, 39 are disposed on radial lines around the main torch axial center, and the anodes 10A, 40 of the respective sub-torches 2, 39 are surrounded by outer sheathes 11, 41. The internal walls of the outer sheathes 11, 41 are provided with cathodes. <P>COPYRIGHT: (C)2010,JPO&INPIT |
