Abstract: A system for reducing flame holding within a combustor includes a high pressure plenum and a head end plenum defined within the combustor. A cap assembly defines an inner plenum within the combustor and a fuel nozzle passage that extends through the cap assembly. A primary fuel nozzle has an annular burner tube that at least partially defines a premix flow passage through the cap assembly. The primary fuel nozzle and the burner tube at least partially define an inlet to the premix flow passage. A high pressure flow passage and a cooling flow passage are defined within the combustor. The high pressure flow passage defines a flow path between the high pressure plenum and the inner plenum, and the cooling flow passage defines a flow path between the high pressure plenum and the head end plenum.

Abstract: A system for supplying a working fluid to a combustor includes a fuel nozzle, a combustion chamber disposed downstream from the fuel nozzle, an inner flow sleeve that circumferentially surrounds the combustion chamber and a plurality of injectors circumferentially arranged around the inner flow sleeve. The plurality of injectors provide for fluid communication through the inner flow sleeve and into the combustion chamber downstream from the fuel nozzle. The system further includes an outer air shield that defines an injection air plenum that surrounds the plurality of injectors. An inlet passage extends through the outer air shield to define a flow path into the injection air plenum. An outer sleeve is slidingly engaged with the outer air shield. The outer sleeve has a first position that restricts flow through the inlet passage and a second position that increases flow through the inlet passage.
