摘要

A combustor (200) includes a first combustion chamber (202), a pre-mixing primary fuel-nozzle assembly (210) associated with the first combustion chamber (202), a second combustion chamber (204), and a secondary fuel-nozzle assembly (212) associated with the second combustion chamber (204). The pre-mixing primary fuel-nozzle (210) assembly includes a number of vanes (222) configured to swirl airflow, each vane comprising a number of fuel injection holes (224) configured to inject fuel into the airflow.
