Combustor and method for distributing fuel in the combustor

A combustor includes a tube bundle (32)that extends radially across at least a portion of the combustor. The tube bundle includes an upstream surface (34) axially separated from a downstream surface (36). A plurality of tubes (30) extends from the upstream surface through the downstream surface, and...

Beschreibung
Zusammenfassung:	A combustor includes a tube bundle (32)that extends radially across at least a portion of the combustor. The tube bundle includes an upstream surface (34) axially separated from a downstream surface (36). A plurality of tubes (30) extends from the upstream surface through the downstream surface, and each tube provides fluid communication through the tube bundle. A baffle (50) extends axially inside the tube bundle between adjacent tubes. A method for distributing fuel in a combustor includes flowing a fuel (44) into a fuel plenum (40) defined at least in part by an upstream surface (34), a downstream surface (36), a shroud (38), and a plurality of tubes (30) that extend from the upstream surface to the downstream surface. The method further includes impinging the fuel against a baffle (50) that extends axially inside the fuel plenum between adjacent tubes (30).
