ABSTRACT:
An improved burner for the combustion of coal, oil or gas places a plurality of retractable and rotatable gas elements in close proximity to the outlet end of a tubular burner nozzle of the burner which are shielded from combustion air provided around the tubular burner nozzle by a flame stabilizing ring having a plurality of openings adapted to closely receive each of the plurality of retractable and rotatable gas elements. Eddies produced by the flame stabilizing ring create a low oxygen/fuel rich flame resulting in reduced NO.sub.x formation.
