STABILIZATION OF A LOW TEMPERATURE PLASMA ARC BY TWO LIQUIDS

摘要

Method of and apparatus for stabilizing a plasma stream by the use of two different stabilization liquids. The plasma arc is stabilized in the discharge chamber by a whirl of first stabilization liquid containing at least one element chosen from the group consisting of carbon and vitrogent and the plasma arc is stabilized in the stabilization channel by a second stabilization liquid differing in its boiling point from the first stabilization liquid. Between the discharge chamber of the burner and the stabilization channel there is provided a transition space from which there lead outlets for the stabilization liquids. In the transition space there may be placed an orifice plate divide in said space into two sub-spaces. From the stabilization channel upstream of the front nozzle of the burner there may be provided an outlet for the second stabilization liquid, which is disposed in the stabilization channel. In accordance with the invention the stabilization system of the plasma burner of torque is divided into two comparatively independent circuits.
