A system includes a multi-tube fuel nozzle. The multi-tube fuel nozzle includes a fuel conduit, a fuel chamber coupled to the fuel conduit, and multiple tubes concentrically arranged in multiple rows about a central axis of the multi-tube fuel nozzle and extending through the fuel chamber to a downstream end portion of the multi-tube fuel nozzle. The multiple tubes include fluids flow and different flow control features including at least one of different fuel/air premixing ratios, different tube diameters, or different outlet distances relative to the downstream end portion. |
