ABSTRACT:
Plasma jets are converged in encircling relationship about a common axis along which a reactant stream is introduced. The reactant stream is confined by the converging and confining plasma jets the shape and direction of flow of which are predefined by converging plasma gas passages concentric with the longitudinal axis. Each plasma gas passage has a minor axis substantially radial to the common axis and a major axis substantially perpendicular to the minor axis at their point of intersection. A body member through which the discrete passages formed is provided with a plurality of cooling passages, some of which extend into and cool fins formed between adjacent plasma gas passages and thereby cool the reactant stream.
