Patent ID: 8057221

Claim:
A method for combustion in a heating furnace of a fuel and an oxidant including gaseous oxygen, wherein the fuel and oxidant are supplied to a burner head, said method comprising the steps of: injecting fuel and oxidant via the burner head through at least two pairs of spaced apart nozzles, wherein each pair of nozzles is defined by a separate fuel nozzle for supplying only fuel and spaced therefrom a separate oxidant nozzle for supplying only oxidant, and wherein the separate and spaced apart fuel and oxidant nozzles have respective fuel and oxidant central axes and each of the fuel nozzle axes and each of the oxidant nozzle axes are spaced from each other and are each parallel to each other to cause both fuel and oxidant to flow from respective separate and spaced apart fuel and oxidant nozzles in the burner head and in the same direction relative to a burner head central axis; uniformly distributing spaced apart individual separate fuel only and individual separate oxidant only nozzles of the nozzle pairs over a burner head surface that faces into the furnace and within an outer circumference of the burner head, wherein the pairs of individual and separate fuel only and individual and separate oxidant only nozzles are uniformly alternately distributed in a circumferential direction relative to the burner head central axis and are uniformly radially distributed outwardly from the burner head central axis; and circumferentially positioning a separate oxidant nozzle on each side of a separate fuel nozzle, wherein the fuel only nozzles of the at least two pairs of spaced apart nozzles are not concentric with a flow of oxidant.
