A combustor includes an end cap (20), a combustion chamber (24) downstream from the end cap (20), and a plurality of tubes (34) that extends through the end cap (20) to provide fluid communication through the end cap (20) to the combustion chamber (24). A casing (12) surrounds the end cap (20), and a conduit (18) extends from the casing (12) to the end cap (20). A duct (60) extends around the conduit (18) and inside the end cap (20) to provide fluid communication to the end cap (20). A method for supplying fuel to a combustor (10) includes flowing a working fluid (14) through a plurality of tubes (34) that extends axially through an end cap (20), supplying a first fluid through a conduit (18) into the end cap (20), and supplying a second fluid through a duct (60) spiraling around the conduit (18) into the end cap (20). |
