Abstract
An axial fuel stage (AFS) injector includes a mixing member including a plurality of axially elongated mixing chambers therebetween. Inlets of the mixing chambers are axially wavy. A high-pressure (HP) air injection member defines a set of HP air jets spaced from the axially wavy inlet of each axially elongated mixing chamber. A fuel plenum in the mixing member delivers fuel from a fuel source to a set of fuel injectors in each mixing chamber. Each set of HP air jets is configured to direct an HP air from an HP air source and, optionally, to draw a low-pressure (LP) air from an LP air source to direct the LP air with the HP air and the fuel into the axially wavy inlet of a respective axially elongated mixing chamber. The axially elongated mixing chambers direct the air-fuel mixture into the combustion liner for combustion in a secondary combustion zone thereof.
