ABSTRACT:
Past systems have attempted to cool the combustor end or tip of fuel injection nozzles, however, such methods have failed to attain adequate cooling and life. The present system or structure for cooling a tip or combustion end of a fuel injection nozzle is accomplished with a twofold structure. First, a plurality of openings being acutely positioned in the combustor end about a plurality of base circles provide effective air-sweep cooling. Secondly, the convection cooling of a back face and a combustion face provides effective convection cooling. The two structures are combined to provide an effective, efficient cooling of the combustor end or tip. The combustor end of the fuel injection nozzle is maintained at a temperature low enough to prevent failure of the combustor end through oxidation, cracking and buckling and the air-sweep avoids carbon deposits on the combustor face.
