An oxygen-fuel burner for a glass-melting furnace generally includes a first (or inner) conduit for fuel, a second (or middle) conduit for waste glass cullet, and a third (or outer) conduit for combustion oxygen. The first, second, and third conduits are nested and define respective paths for fuel, cullet, and oxygen flows. A cullet supply funnel is coupled to the second conduit such that cullet can be introduced into the second conduit through the funnel. Organic contaminants in the waste glass cullet are incinerated in an almost pure oxygen environment proximate where cullet particles exit from the burner and prior to reaching the glass surface below.

Aspects of the present disclosure include branching fluid passages in an apparatus that reduce turbulent flow and generate evenly distributed fluid pressure as the fluids branch off into the different passages. In some embodiments, the branching passages may be subdivided into two sets: the branching passages for the liquid fuel and the branching passages for the liquid oxidizer. In some embodiments, the two sets of passages are carefully designed in an elegant yet extremely intricate manner that is optimized for proper fluid flow and maximal burn efficiency. The ends of all of the passages meet at the injector interface, which dispense the liquids into the combustion chamber for ignition. Generally, these designs are achieved through additive manufacturing, and would be extremely difficult, if not impossible, to be manufactured using traditional techniques. 1.
