Combustor and method for supplying fuel to a combustor

A combustor (10) includes an end cap (18) having an upstream surface (26) axially separated from a downstream surface (28). A casing (12) circumferentially surrounds at least a portion of the end cap (18) to define an annular passage (20). A first tube bundle (40) extends from the upstream surface (...

More Information
Summary:A combustor (10) includes an end cap (18) having an upstream surface (26) axially separated from a downstream surface (28). A casing (12) circumferentially surrounds at least a portion of the end cap (18) to define an annular passage (20). A first tube bundle (40) extends from the upstream surface (28) through the downstream surface to provide fluid communication through the end cap (18). A first fuel conduit (44) is in fluid communication with the first tube bundle (40) to supply fuel through the annular passage (20) to the first tube bundle (40), and a liquid fuel supply (48) is in fluid communication with the first tube bundle (40) through the first fuel conduit (44). A method for supplying fuel to a combustor (10) includes flowing a working fluid (14) through a first tube bundle (40) and flowing a liquid fuel through an annular passage (20) surrounding the end cap (18) and into the first tube bundle (40).
