Abstract
A feedstock injector for connection to a source of heated gas comprises a converging channel extending from the upstream end to the downstream end of the injector. A splitting arm extends diagonally within the converging channel, the splitting arm comprising two symmetrically opposed surfaces extending from the inlet to the outlet ends of the converging channel. A feedstock injection passage opens axially at the downstream end of the splitting arm. The gas stream discharged by the injector contacts and entrains the feedstock with improved uniformity.
Claims25
A feedstock injector for axial injection of feedstock into the stream of gas of a spray torch, the injector having a longitudinal axis and comprising:
- (a) an inlet end for receiving the stream of gas at an upstream end of the injector;
- (b) an outlet end to discharge the stream of gas at a downstream end of the injector;
- (c) a converging channel co-axial with the longitudinal axis having a frustroconically shaped wall extending between the inlet and outlet ends and converging downstream of the outlet end toward a point of convergence on the longitudinal axis;
- (d) a splitting arm extending from a first region of the wall of the converging channel to a second region opposite to the first region, the arm comprising a pair of opposed surfaces, arranged symmetrically with respect to a splitting arm plane which includes the longitudinal axis, and extending in a direction between the inlet and outlet ends;
- and
- (e) a feedstock passage passing through the splitting arm, the passage having an outlet end directed toward the point of convergence for directing feedstock axially in a downstream direction from the outlet end.
