Abstract: A fuel nozzle includes a center body and a shroud circumferentially surrounding at least a portion of the center body to define an annular passage between the center body and the shroud. A plurality of vanes extend radially between the center body and the shroud in the annular passage. A first ceramic extension extends downstream from the shroud to define at least a portion of the annular passage downstream from the shroud.
