Claim Text:
1. A combustor, comprising: a. a tube bundle that extends radially across at least a portion of the combustor, wherein the tube bundle comprises an upstream surface axially separated from a downstream surface, wherein the upstream surface is defined by a first plate and the downstream surface is defined by a second plate, wherein the first plate and the second plate define a fuel plenum therebetween; b. a plurality of tubes that extends from the upstream surface through the downstream surface, wherein each tube provides fluid communication through the tube bundle, wherein each tube defines a fuel port in fluid communication with the fuel plenum and disposed between the upstream surface and the downstream surface of tube bundle, wherein the plurality of tubes comprises a first row of tubes annularly arranged about an axial centerline of the tube bundle and a second row of tubes coaxially aligned with and spaced radially outwardly from the first set of tubes; and c. a baffle that extends axially inside the fuel plenum and extends circumferentially around the first row of tubes, wherein the baffle is positioned radially between the first row of tubes and the second row of tubes, wherein the baffle defines a plurality of fuel flow paths for fuel to flow radially outwardly from the first row of tubes towards the second row of tubes.
