A gas delivery system (10) and a method of metering combustible gas (B) to a combustor having a combustion chamber (14) and a nozzle (12) adapted to be in fluid communication with the combustion chamber (14). The nozzle (12) has an inner surface (18) defining a converging portion (20), a throat (22) and a diverging portion (24). The converging portion (20) is positioned upstream of the throat (22), and the diverging portion (24) is positioned downstream of the throat (22). The converging portion (20) of the nozzle (12) is adapted to be in fluid communication with a gas source (26) upstream of the converging portion (20). An end (32) of a conduit (30) is positioned at the throat (22), and the conduit (30) is adapted to be in fluid communication with a combustible gas source (34).
