Abstract
A dual fuel injector includes an apparatus for injecting liquid pilot fuel into a gas turbine engine. The injector includes a liquid pilot fuel feedline having an outlet that sprays fuel on the conically-shaped pintle swirler that causes the fuel to form a cylindrically-shaped film on the interior of a pilot fuel-air mixing passage. The film of fuel is broken up into droplets at a downstream end of the pilot fuel-air mixing passage by shearing forces exerted on the film by separate streams of air flowing within and externally of the pilot fuel-air mixing passage.
