Document Type and Number:
Japanese Patent JPH08509058
Kind Code:
A
Abstract:
Past fuel injection nozzles have attempted to provide a structure to reduce tip temperatures. Such nozzles have failed to attain adequate reduction of tip temperatures without increasing the quantity of cooling air required. The present fuel injector structure has resulted in reduced tip temperatures without increasing the quantity of cooling air required. The structure includes a shell having an inner member positioned therein forming a first chamber therebetween, an end piece forming a second chamber between the inner member and the end piece. An inner body has a plurality of first angled passages formed therein and communicates between the second chamber and a passage. A flow of combustor air through the second chamber contacts an air side of the end piece resulting in a combustor side being cooled. The unique structure of the fuel injector nozzle provides improved tip cooling without increasing the quality of cooling air and improves the efficiency of the gas turbine engine.
