摘要： Flow adjustment orifice systems for fuel nozzles include a metering plate that connects to an air/fuel inlet end of a fuel nozzle and a plurality of metering orifices disposed about the metering plate that align with a plurality of air/fuel inlet orifices on the air/fuel inlet end of the fuel nozzle, wherein at least one of the plurality of metering orifices reduces an open cross-sectional area for at least one of the air/fuel inlet orifices.
