Claim Text:
1. A fuel nozzle assembly comprising: a conduit defining a fuel inlet and a fuel outlet, operable to convey a fuel stream comprising a solid particulate fuel entrained in a fluid, the conduit having a flow area defined by an interior surface of the conduit, wherein the fuel stream is conveyed to the fuel inlet by an elbow-shaped conduit that results in the fuel stream splitting into at least a first sub-flow fuel stream and a second sub-flow fuel stream diverging from each other concentrated along the interior surface of the conduit; a first flow deflector extending inwardly from the interior surface of the conduit and longitudinally parallel to a longitudinal axis defining the conduit along the interior surface of the conduit, the first flow deflector having major surface side walls defining the first flow deflector extending longitudinally parallel to the longitudinal axis defining the conduit along the interior surface to disrupt the at least first sub-flow fuel stream to entrain the solid particles back into the fuel stream; and a second flow deflector extending inwardly from the interior surface of the conduit and longitudinally parallel to the longitudinal axis defining the conduit along the interior surface of the conduit, the second flow deflector having major surface side walls defining the second flow deflector extending longitudinally parallel to the longitudinal axis defining the conduit along the interior surface to disrupt the at least second sub-flow fuel stream to entrain the solid particles back into the fuel stream, wherein at least one of the first and second flow deflectors each have substantially triangular cross sections along the longitudinal axis defining the conduit, each having the sidewalls joined at terminal ends thereof defining an apex therebetween.
