| 主权项 | 1. A combustor for combusting a flow of fuel and a flow of air, comprising: a plurality of fuel nozzles; a lean pre-nozzle fuel injection system positioned upstream of the plurality of fuel nozzles to premix the flow of fuel and the flow of air; and a casing positioned about a cap baffle, wherein the casing and the cap baffle form a premixing annulus having a length defined between the lean pre-nozzle fuel injection system and a distal end of the cap baffle, wherein the lean pre-nozzle fuel injection system is disposed about an upstream end of the cap baffle, wherein the plurality of fuel nozzles are positioned downstream of the premixing annulus, wherein the lean pre-nozzle fuel injection system is positioned upstream of the premixing annulus, and wherein the distal end of the cap baffle and a corresponding portion of the casing are curved inward towards the plurality of fuel nozzles. | ||
