Cooling of integrated combustor nozzle of segmented annular combustion system
First Claim
1. An integrated combustor nozzle of an annular combustor, comprising:
- a fuel injection panel extending radially between an inner liner segment and an outer liner segment, the fuel injection panel including a forward end portion at an upstream end of the annular combustor, an aft end portion, a first side wall, a second side wall, a plurality of premixing channels defined between the first side wall and the second side wall, and a plurality of injection outlets defined along at least one of the first side wall and the second side wall, the aft end portion of the fuel injection panel defining a turbine nozzle portion of the fuel injection panel;
wherein the fuel injection panel further comprises an interior portion defined within the fuel injection panel between the first side wall and the second side wall, wherein the interior portion includes a plurality of walls that extend between an inner surface of the first side wall and an inner surface of the second side wall, thereby partitioning the semi-hollow interior portion into a plurality of air cavities.

Abstract
A segmented annular combustion system includes integrated combustor nozzles, each of which has a fuel injection panel disposed radially between an inner liner segment and an outer liner segment. The fuel injection panel includes an aft end portion, a first side wall, a second side wall, premixing channels defined between the first side wall and the side wall, and injection outlets defined along at least one of the first side wall and the second side wall. The aft end portion defines a turbine nozzle portion. An interior portion between the first side wall and the second side wall includes walls that extend between the first and second side walls, thereby partitioning the interior portion into discrete air cavities. The air cavities and the liner segments may be cooled by impingement inserts or panels.
