Title: Dry low NOx combustion system with pre-mixed direct-injection secondary fuel nozzle

Patent ·
OSTI ID:1111146
; ; ;

A combustion system includes a first combustion chamber and a second combustion chamber. The second combustion chamber is positioned downstream of the first combustion chamber. The combustion system also includes a pre-mixed, direct-injection secondary fuel nozzle. The pre-mixed, direct-injection secondary fuel nozzle extends through the first combustion chamber into the second combustion chamber.
