    Abstract: A method of melting a charge in a double-pass tilt rotary furnace having a door, including operating a first burner at a first firing rate, the first burner being mounted in a lower portion of the door and producing a first flame having a length; operating a second burner at a second firing rate, the second burner being mounted in an upper portion of the door and producing a second flame having a length, the second flame being distal from the charge relative to the first flame; in an initial phase when the solids in the charge impede the first flame, controlling the second firing rate to be greater than the first firing rate; and in an later phase after melting of the solids in the charge sufficiently that the first flame is not impeded, controlling the first firing rate to be greater than the second firing rate.

    Abstract: A selective oxy-fuel burner for mounting in a charge door of a rotary furnace, including at least two burner elements each oriented to fire into different portions of the furnace, each burner element including a selective distribution nozzle configured to flow a first reactant; and a proportional distribution nozzle configured to flow a second reactant; at least one sensor to detect one or more process parameters related to furnace operation; and a controller programmed to independently control the first reactant flow to each selective distribution nozzle based on the detected process parameters such that at least one burner element is active and at least one burner element is passive; wherein the second reactant is substantially proportionally distributed to the proportional distribution nozzles; and wherein the first reactant is one of a fuel and an oxidant and wherein the second reactant is the other of a fuel and an oxidant.
