ABSTRACT:
A self-actuating nozzle guide vane assembly for a turbine type power plant fuel nozzle increases airflow during the higher power regimes. The fuel nozzle inlet guides employ primary and secondary swirlers where the primary swirlers continuously deliver compressor air around the fuel nozzles and the secondary swirlers deliver compressor air solely when the inlet temperature goes above a predetermined threshold value in another embodiment.
