PROBLEM TO BE SOLVED: To provide a liquid cartridge having a passively fueled premixed air blast circuit for gas operation.SOLUTION: A gas/liquid fuel nozzle assembly includes: a premixing tube bundle having an array of mixing tubes; a fuel plenum delivering fuel to the mixing tubes; a cartridge tube disposed within the fuel plenum; and a liquid fuel cartridge disposed within the cartridge tube. The liquid fuel cartridge is spaced from the cartridge tube to define an annulus. The cartridge tube and the fuel plenum are constructed in fluid communication such that gas fuel in the plenum is injected into the annuls.
