Abstract
A fuel injection assembly for a combustor of a gas turbine includes a fuel injector configured to couple to an outer sleeve of the combustor. A boss is configured to couple to a combustion liner of the combustor at a position axially and circumferentially aligned with the fuel injector. An insert is removably coupled to the boss. The insert includes a flange portion and an annular wall portion extending from the flange portion and defining a mixing channel. The insert defines a plurality of partial direct injectors spaced apart from one another and disposed about the mixing channel. A combustor including such a fuel injection assembly is also provided.

A fuel injection assembly for a combustor of a gas turbine, the fuel injection assembly comprising:
- a fuel injector configured to couple to an outer sleeve of the combustor;
- a boss configured to couple to a combustion liner of the combustor at a position axially and circumferentially aligned with the fuel injector;
- and
- an insert removably coupled to the boss, the insert comprising a flange portion, an annular wall portion extending from the flange portion, the annular wall portion defining a mixing channel, wherein the insert defines a plurality of partial direct injectors spaced apart from one another and disposed about the mixing channel.
A combustor comprising:
- at least one fuel nozzle;
- a combustion liner extending downstream from the fuel nozzle;
- an outer sleeve spaced apart from and surrounding the combustion liner such that an annulus is defined therebetween;
- and
- a fuel injection assembly disposed downstream from the at least one fuel nozzle, the fuel injection assembly comprising:
- a fuel injector coupled to the outer sleeve of the combustor;
- a boss coupled to the combustion liner of the combustor, the boss being axially and circumferentially aligned with the fuel injector;
- and
- an insert removably coupled to the boss, the insert comprising a flange portion, an annular wall portion extending from the flange portion, the annular wall portion defining a mixing channel, wherein the insert defines a plurality of partial direct injectors spaced apart from one another and disposed about the mixing channel.
