Abstract
A combustor head end section includes an integrated cooling system. The combustor head end section includes: a bundled tube fuel nozzle assembly having a forward plate facing a head end air plenum, an aft plate facing a combustion chamber, and premixing tubes extending from the forward plate to the aft plate. A side wall extends circumferentially around the premixing tubes and extends axially from the forward plate to the aft plate. The forward plate, the aft plate, and the side wall define a fuel plenum, and each premixing tube includes at least one fuel injection hole in fluid communication with the fuel plenum. The head end air plenum is in fluid communication with the combustion chamber, via the premixing tubes. The integrated cooling system comprises an air flow passage integral with an exterior surface of a respective premixing tube and extending from the forward plate to the aft plate.
