Abstract
An axial fuel stage (AFS) injector includes a mixing member having multiple mixing chambers in fluid communication with a combustion liner of a combustor, and a set of fuel injectors defined in a side wall of each mixing chamber. A high-pressure (HP) air injection member defines a set of HP air jets spaced from the inlet of each mixing chamber. A fuel plenum is defined in the mixing member to deliver fuel to each set of fuel injectors. Each set of HP air jets is configured to direct a HP air from a HP air source, and optionally to draw a low-pressure (LP) air from a LP air source to direct the LP air with the HP air, into the inlet of a respective mixing chamber where fuel is injected. The mixing chambers direct the air-fuel mixture into the combustion liner for combustion in a secondary combustion zone thereof.
