Claim Text:
1. A combustor, comprising: an outer casing, a portion of the outer casing at least partially defining a fuel conduit therein; an end cap assembly that extends radially and axially within the outer casing, the end cap assembly having an annular cap shield that extends axially between an upstream surface and a downstream surface, a first fuel plenum defined within the cap shield between the upstream surface and a first barrier plate and a second fuel plenum defined within the cap shield between the first barrier plate and a second barrier plate, a plurality of tubes that provide for fluid communication through the upstream surface, the first fuel plenum, the first barrier plate, the second fuel plenum, the second barrier plate and the downstream surface, wherein an outer surface of the cap shield is radially spaced from an inner surface of the casing to define an annular passage therebetween; a plurality of airfoils that extend radially through the annular passage from the inner surface of the outer casing to the outer surface of the cap shield, wherein at least one airfoil of the plurality of airfoils provides for fluid communication between the fuel conduit and at least one of the first fuel plenum or the second fuel plenum; and an axially extending fuel conduit that extends through the upstream surface into the first fuel plenum.
