More Information
Summary:A bundled tube fuel nozzle assembly for a gas turbine combustor includes: 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. An interior side wall extends circumferentially around the first plurality of premixing tubes and defines an interior fuel plenum, and an exterior side wall extends circumferentially around the interior side wall and defines an exterior fuel plenum. Both side walls extend axially from the forward plate to the aft plate. The interior fuel plenum is in fluid communication with the exterior fuel plenum. Each premixing tube includes at least one fuel injection hole therethrough, which is in fluid communication with the interior fuel plenum. The head end air plenum is in fluid communication with the combustion chamber, via inlet ends of the premixing tubes.
