Abstract
An axial fuel stage (AFS) injector includes a mixing member and a high pressure (HP) air-fuel injection member. The injection member includes HP air-fuel injectors including an inner wall defining an inner air jet and an outer wall surrounding and concentric with the inner wall and defining an outer air jet loop therebetween. A spacer member spaces the walls. A plurality of fuel injector passages extends from the outer wall through the spacer member and the inner wall to the inner air jet. Each fuel injector passage has an end including a fuel injector directed into the inner air jet. A fuel plenum is configured to deliver a fuel to each of the fuel injectors. The inner air jets and the air jet loops are configured to direct a high-pressure air flow from a high-pressure air source with the fuel into the inlet of the mixing member.
