<p>The present invention provides a plasma torch, comprising: a base flame generating module which generates a base flame by plasma discharge; a first housing which guides the base flame so as to discharge the base flame to a first discharge path; a fuel material spraying module which generates a main flame by injecting a fuel material containing fuel and an oxidizing agent to the base flame such that the spraying direction intersects the direction of the first discharge path; and a second housing which guides the plasma flame so as to discharge the plasma flame to the outside through a second discharge path such that, in order to reflect the momentum caused by the injected fuel material, the direction of the second discharge path is positioned between the direction of a first diagonal line and the direction of the first discharge path or is the same as the direction of a second diagonal line which is the same as that of the first diagonal line. Therefore, since the accumulation of soot around a discharge hole of the plasma flame torch is reduced, clogging of the discharge hole can be prevented.</p> |
