Abstract
A system for establishing a single coherent gas jet from a plurality of initial gas jets ejected from a single lance wherein the initial gas jets are themselves coherent, are angled inward, and are surrounded by a flame envelope. The initial coherent gas jets merge to form a single coherent jet and the gases of the initial gas jets do not substantially interact within this single coherent jet for the length of the resulting single coherent gas jet.
