Zusammenfassung:	A transient heating burner (10) including at least two burner elements (20) each having a distribution nozzle (22) configured to flow a fuel, and an annular nozzle (24) surrounding the distribution nozzle (22) and configured to flow an first oxidant, at least one staging nozzle (30) configured to flow a second oxidant, and a controller (100) programmed to independently control the fuel flow to each distribution nozzle (22) such that at least one of the distribution nozzles is active and at least one of the distribution nozzles is passive, wherein an active distribution nozzle fuel flow is greater than an average fuel flow to the distribution nozzles (22) and a passive nozzle fuel flow is less than the average fuel flow, and to control a staging ratio to be less than or equal to about 75%.
