Abstract
A burner apparatus for the combustion of a fuel and an oxidizer includes a burner block having a fuel line for feeding fuel to a fuel port opening into a combustion chamber and a plurality of primary and secondary oxidizer lines positioned around the fuel line for feeding an oxidizer to a primary and secondary oxidizer port to the combustion chamber for combustion with the fuel from the fuel port. The primary and secondary oxidizer lines and ports are spaced around the fuel port so that controlling the oxidizer is used to change the position and shape of the flame in the combustion chamber. First and second oxidizer valves are located in the oxidizer feed lines and vary the amount of oxidizer fed through the oxidizer line so that the first and second oxidizer control valves for each set of oxidizer lines are spaced around the fuel port to allow both the position and the shape of the burner flame to be controlled. A method of controlling a flame's position and shape in a burner combustion chamber is provided by varying the feed of oxidizer to each pair of oxidizer ports and proportioning the oxidizer between each primary and adjacent secondary oxidizer port.
