摘要:
An oxy-fuel boost burner for a regenerative furnace having a pair of regenerator ports configured to alternately fire into and exhaust from the furnace, including at least one burner element corresponding to each of the regenerator ports by being positioned to fire into a complimentary region 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, and a controller programmed to identify which regenerator port is currently firing and which is currently exhausting and to independently control the first reactant flow to each selective distribution nozzle such that the at least one burner element corresponding to the currently firing regenerator port has a greater than average first reactant flow and the at least one burner element corresponding to the currently exhausting regenerator port as a less than average first reactant flow.
摘要:
A selective oxy-fuel burner (10) for mounting in a charge door of a rotary furnace, including at least two burner elements (20) each oriented to fire into different portions of the furnace, each burner element including a selective distribution nozzle (22) configured to flow a first reactant; and a proportional distribution nozzle (24) 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 (22) 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 (24); 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.
