PILOTED AIRBLAST LEAN DIRECT FUEL INJECTOR

摘要

A gas turbine fuel injection system of the lean direction injector type to reduce NOx emissions is provided. The configuration includes a pilot fuel injector (66), a pilot swirler (28), a main injector (68), and inner (22) and outer (24) main swirlers. An air splitter (26) between the pilot (28) and main (22) swirlers is provided to create a bifurcated recirculation zone (52).
