ABSTRACT:
An air premixed natural gas burner having reduced thermal and prompt NO.sub.x emissions employs a central, cylindrical core chamber and an outer annular chamber separated by a hollow barrel having a plurality of gas spuds at a front end of the burner adjacent to a burner throat. The plurality of gas spuds introduces natural gas into a core chamber air flow passing through a fixed swirler and controlled by a sliding air flow damper associated with the central, cylindrical core chamber. A reduced air/fuel stoichiometric ratio (of approximately 0.6) is preferably maintained at an outlet of the central, cylindrical core chamber. The balance of the combustion air is provided through the outer annular chamber to maintain an overall or cumulative burner stoichiometric ratio of approximately 1.05.
