COMBUSTOR AND METHOD FOR SUPPLYING FUEL TO A COMBUSTOR

A combustor includes an end cap having an upstream surface axially separated from a downstream surface. A casing circumferentially surrounds at least a portion of the end cap to define an annular passage. A first tube bundle extends from the upstream surface through the downstream surface to provide...

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