Abstract:
1. A combustor, comprising: an end cap assembly configured to extend radially across at least a portion of the combustor, wherein the end cap includes an upstream surface axially separated from a downstream surface; a cap shield that circumferentially surrounds at least a portion of the upstream and downstream surfaces; a plurality of tubes that extends from the upstream surface through the downstream surface to provide fluid communication through the end cap; a barrier that extends radially within the cap shield and that is axially spaced from the downstream surface; a first baffle that extends radially within the cap shield and that is axially spaced from the barrier, wherein the first baffle and the barrier define a first plenum therebetween; a radial gap defined between the first baffle and an inner surface of the cap shield; and a plate that extends radially inside the cap shield between the first baffle and the upstream surface, wherein the plate and the first baffle define a second plenum therebetween, wherein the radial gap provides for fluid communication between the first plenum and the second plenum.
