Combustor and method for distributing fuel in the combustor

摘要

A combustor includes a plurality of tubes (20) arranged in a tube bundle (22) and supported by at least one plate (24) that extends radially within the combustor, wherein each tube (20) includes an upstream end (34) axially separated from a downstream end and provides fluid communication through the tube bundle (22). A flow conditioner (18) extends upstream from the upstream end (34) of one or more of the plurality of tubes (20), and a radial passage (40) extends through the flow conditioner (18). A method for distributing fuel in a combustor including flowing a working fluid (16) through a flow conditioner (18) that extends from a tube (20) that is configured in a tube bundle (22) comprising a plurality of tubes (20) and that is supported by at least one plate (24). The flow conditioner (18) includes at least one radial passage (40) to impart radial swirl to the working fluid (16). Flowing a fuel through an annular insert (50) that is at least partially surrounded by the flow conditioner (18).
