Abstract
Past systems have attempted to provide a combustion system to reduce NOx pollution, however, such methods have failed to attain adequate reductions in NOx pollution. The present system or structure for for reducing NOx includes a pilot fuel system and a premixed supply system to reduce the NOx to a workable level. The pilot system uses a device for supplying combustible fuel to the fuel injection nozzle generally along a combustion axis during all or a portion of the operating conditions of the engine. Low NOx is maintained by using a device for supplying combustible fuel into each of a plurality of spaces formed between a plurality of swirler vanes. Low NOx is further maintained by having the cooling fluid used to cool the fuel injection nozzle mixed with the fuel and air from the spaces prior to entering the combustion chamber.
