Abstract

A gaseous process stream (11) that can be directed into a workspace (22) or toward a workpiece is formed by feeding fuel (5), oxidant (6) and process material (10) into a thermal nozzle (1). The fuel combusts in the thermal nozzle with the oxidant and with combustible components, if any, of the process material, to form the gaseous process stream which is emitted from the thermal nozzle at high and controllable velocity and momentum.
