Abstract (en)

[origin: WO9744618A1] A burner apparatus and method for the combustion of a fuel and an oxidizer includes a burner block (7) having a fuel line (1) for feeding fuel to a fuel port opening (12) into a combustion chamber and a plurality of oxidizer lines (32, 33, 34) positioned around the fuel line (1) for feeding an oxidizer to oxidizer ports (17, 18, 19, 20) to the combustion chamber for combustion with the fuel from the fuel port (12). The oxidizer lines and ports (13, 14, 15, 16 and 17, 18, 19, 20) are spaced around the fuel port (12) so that controlling the oxidizer is used to change the position and shape of the flame in the combustion chamber. Oxidizer control valves (36, 37, 38, 39) vary the amount of oxidizer fed through the oxidizer line so that the oxidizer control valves (36, 37, 38, 39) for each set of oxidizer lines are spaced around the fuel port (12) to allow both the position and shape of the burner flame to be controlled.
