Abstract
An axial fuel stage (AFS) injector includes a mixing member defining a mixing chamber having an inlet and an outlet in fluid communication with a combustion chamber of the combustor. A high pressure (HP) air-fuel injection member includes at least one row of HP air-fuel injectors for directing an air-fuel mixture into the mixing chamber. Each HP air-fuel injector includes two opposing sidewalls and a middle wall extending longitudinally between the two opposing sidewalls. The middle wall and each opposing sidewall define an elongated HP air jet therebetween. A fuel plenum delivers fuel from a fuel source to fuel injector(s) defined in a radially inner end of the middle wall. Each elongated HP air jet is configured to direct an HP air flow toward the inlet of the mixing chamber from an HP air source in a same direction as a fuel flow from the at least one fuel injector.
