Disclosed is a combustor including a baffle plate having at least one through baffle hole and at least one fuel nozzle extending through the at least one through baffle hole. At least one diluent shroud is affixed to the at least one baffle plate and is configured to guide a diluent flow toward a mixing chamber of the at least one fuel nozzle. Further disclosed is a method for introducing a diluent flow into a mixing chamber of a fuel nozzle including urging the diluent flow from a plenum through a baffle plate gap between a baffle plate and an outer surface of the fuel nozzle. The diluent flow is directed via at least one diluent shroud extending from the baffle plate toward a plurality of air swirler holes extending through a fuel nozzle tip. The diluent flow is flowed through the plurality of air swirler holes into the mixing chamber.

Diluent shroud for combustor

A gas turbine combustor liner has at least one circumferential row of air holes adapted to supply air in a radial direction into a combustion chamber within the liner. One or more of the air holes have a thimble fixed therein, the thimble having a substantially circular body and a pair of lips extending from an interior end of the thimble in diametrically opposed upstream and downstream directions.

Combustion liner thimble insert and related method

A combustor for a turbine including a combustor liner; a first flow sleeve surrounding the combustor liner with a first flow annulus therebetween, the first flow sleeve having at least one cooling aperture formed about a circumference thereof for directing compressor discharge air as cooling air into the first flow annulus; a casing surrounding first flow sleeve with a second flow annulus therebetween, the first flow sleeve having at least one air extraction opening formed about a circumference thereof for directing compressor discharge air from the first flow annulus as extraction air into the second flow annulus; and an extraction port operatively coupled to the casing for extracting the extraction air from the second flow annulus.
