Disclosed is a combustor (10) including a baffle plate (30) having at least one through baffle hole (32) and at least one fuel nozzle (12) extending through the at least one through baffle hole (32). At least one diluent shroud is affixed to the at least one baffle plate (30) and is configured to guide a diluent flow (40) toward a mixing chamber (54) of the at least one fuel nozzle (12). Further disclosed is a method for introducing a diluent flow (40) into a mixing chamber (54) of a fuel nozzle (12) including urging the diluent flow (40) from a plenum (38) through a baffle plate gap (74) between a baffle plate (30) and an outer surface (64) of the fuel nozzle (12). The diluent flow (40) is directed via at least one diluent shroud extending from the baffle plate (30) toward a plurality of air swirler holes (62) extending through a fuel nozzle tip (52). The diluent flow (40) is flowed through the plurality of air swirler holes (62) into the mixing chamber (54). |
