Dual fuel mixing in a multishear fuel injector with a plurality of concentric ducts |
摘要 |
A fuel/mixer injection system for a combustor of a gas turbine engine comprising two major assemblies including a burner-mounted swirler with two outer air passages surrounding a central passage and a piloted air fuel nozzle containing a main fuel injection orifice and a pilot fuel injection orifice the main fuel mixes with swirling air in the central passage and the pilot fuel mixes with the swirling air in the outer air passage. In another embodiment, the piloted fuel nozzle contains an airblast-atomized main fuel injector annulus and a concentric ring with a plurality of circumferentially spaced holes feeds air to the main fuel injector annulus.
