Laster, Walter R.; Martin, Scott M.; Portillo Bilbao, Juan Enrique; Hardes, Jacob; Fox, Timothy A.

A secondary fuel stage (14) of a combustor of a gas turbine engine. The combustor has a main combustion zone (43) upstream of the secondary fuel stage to ignite working gas The secondary fuel stage includes a nozzle (18) with dual outlets (20, 22) oriented with a circumferential component to inject an air-fuel mixture (24) into the combustor. The nozzle is effective to entrain the air-fuel mixture with the working gas (44) such that a peak temperature (46) of the working gas at a location downstream of the secondary fuel stage is less than a peak temperature (50) of working gas if the air-fuel mixture were injected into the combustor with a single outlet nozzle (118).
