A fuel nozzle for a gas turbine engine permits alternate use of different fluid fuels such as gaseous or liquid fuels without intermixing until delivery of the fuel to the combustion chamber. The nozzle provides concentric fuel delivery passages and allows for differing rates of expansion between the two passages.
