Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a system, to a combustion zone, by which a high temperature zone and an NOx emission are reduced.SOLUTION: According to various embodiments, the system includes a turbine fuel nozzle. The turbine fuel nozzle includes a first fuel passage extending to a downstream mixing region, a first air passage extending from an exterior of the turbine fuel nozzle to the downstream mixing region, and a second fuel passage extending into the first air passage upstream in the downstream mixing region.
