A combustor, comprising: an end cap that extends radially across at least a portion of the combustor, wherein the end cap comprises an upstream surface axially separated from a downstream surface and a cap shield circumferentially surrounding the upstream and downstream surfaces (30,32); a first barrier that extends radially in the end cap between the upstream and downstream surfaces (30,32); a first fuel plenum defined within the cap shield between the upstream surface and the first barrier; a first baffle that extends radially in the first fuel plenum upstream from the first barrier; a first conduit extending through the upstream surface into the first fuel plenum, the first conduit orientated to direct a flow of fuel into the first fuel plenum, the flow of fuel being substantially perpendicular to the first baffle; a first circuit of tubes extending through the upstream surface and the downstream surface and in fluid communication with the first fuel plenum; a second fuel plenum defined within the cap shield between the first barrier and the downstream surface; a second baffle that extends radially in the second fuel plenum between the first barrier and the downstream surface; a second conduit extending through upstream surface, through the first fuel plenum, through the first barrier and into the second fuel plenum, the second conduit being orientated to direct a flow of fuel into the second fuel plenum, the flow of fuel being substantially perpendicular to the second baffle; and a second circuit of tubes extending through the upstream surface and the downstream surface and in fluid communication with the second fluid plenum. an end cap that extends radially across at least a portion of the combustor, wherein the end cap comprises an upstream surface axially separated from a downstream surface and a cap shield circumferentially surrounding the upstream and downstream surfaces (30,32); a first barrier that extends radially in the end cap between the upstream and downstream surfaces (30,32); a first fuel plenum defined within the cap shield between the upstream surface and the first barrier; a first baffle that extends radially in the first fuel plenum upstream from the first barrier; a first conduit extending through the upstream surface into the first fuel plenum, the first conduit orientated to direct a flow of fuel into the first fuel plenum, the flow of fuel being substantially perpendicular to the first baffle; a first circuit of tubes extending through the upstream surface and the downstream surface and in fluid communication with the first fuel plenum; a second fuel plenum defined within the cap shield between the first barrier and the downstream surface; a second baffle that extends radially in the second fuel plenum between the first barrier and the downstream surface; a second conduit extending through upstream surface, through the first fuel plenum, through the first barrier and into the second fuel plenum, the second conduit being orientated to direct a flow of fuel into the second fuel plenum, the flow of fuel being substantially perpendicular to the second baffle; and a second circuit of tubes extending through the upstream surface and the downstream surface and in fluid communication with the second fluid plenum.
