Abstract: A burner nozzle and a method of operating the burner nozzle can include a main air/fuel port located centrally within the burner nozzle, and a group of staged gas fuel ports that surrounds the main air-fuel port and which can direct fuel to an established flame zone downstream from the burner nozzle. Furthermore, a trapped vortex chamber can be formed in a wall of the main air/fuel port and can communicate with a group of primary gas ports in a fuel circuit, such that the trapped vortex chamber facilitates flame stability with respect to a flame produced by the burner nozzle.
