Abstract
A burner includes an oxidant feed passage, a fuel feed passage surrounding the oxidant feed passage, an air feed surrounding the fuel feed passage, a movable air flow diverter and, optionally, a flame nozzle. The movable air flow diverter and/or flame nozzle are independently configured to create one or a plurality of gas recirculation regions adjacent the downstream tip of the burner to improve the mixing and reaction of the fuel and oxidant, and overall combustion process efficiency. A related furnace and method for generating a stable flame with the burner are also provided.
Claims22
A burner comprising:
- an oxidant feed passage;
- a fuel feed passage surrounding the oxidant feed passage;
- an air feed surrounding the fuel feed passage;
- and
- a movable air flow diverter positionable in the air feed along at least a portion of the fuel feed passage, and including a side wall constructed to proportion distribution of the air feed.
A furnace, comprising:
- a housing having a wall and an interior;
- and
- a burner engaged with the wall of the housing and in fluid communication with the interior of the housing, wherein the burner comprises:
- an oxidant feed passage,
- a fuel feed passage surrounding the oxidant feed passage,
- an air feed surrounding the fuel feed passage, and
- a movable air flow diverter positionable in the air feed along at least a portion of the fuel feed passage, and including a side wall constructed to proportion distribution of the air feed.
A method of generating a flame from combustion of a fuel, comprising:
- moving an oxidant feed through an oxidant feed passage;
- moving a fuel feed through a fuel feed passage surrounding the oxidant feed passage;
- moving an air feed containing oxidant within an air feed region surrounding the fuel feed passage along the fuel feed passage;
- creating a gas recirculation region immediately downstream from the air feed and the fuel feed passage;
- diverting the air feed for proportioning the air feed around the fuel feed passage for controlling flame stabilization in the gas recirculation region;
- and
- igniting a resulting gas mixture.
