Abstract
A fuel nozzle assembly 32 which extends into a flow path 18 for working medium gases is disclosed. Various construction details which decrease the amount of heat transfer to the fuel are developed. The assembly includes an external heat shield 50 and an internal heat shield 98 which provide longitudinally overlapping insulating gaps 52, 102 between the fuel and the hot working medium gases. In particular, the insulating gap 52 extends to the inlet 94 of the fuel nozzle support.
