Abstract Of The Disclosure Methods and apparatus for combusting fuel-air mixtures while inhibiting the formation of nitrogen oxides are provided. The fuel is discharged from one or more nozzles disposed within a housing, air is caused to flow into the housing whereby it mixes with the fuel and the resulting fuel-air mixture is ignited and combusted. The nozzle or nozzles each include one or more ignition orifices for discharging a first portion of fuel in an ignition zone, one or more primary combustion orifices for discharging a second portion of fuel in a primary combustion zone containing excess air and one or more secondary combustion orifices for discharging the remaining portion of fuel within and downstream of the primary combustion zone whereby the fuel is burned in a secondary combustion zone substantially shielded from direct contact with incoming air by the primary combustion zone.
