SYSTÈME D'INJECTION AVEC INJECTEURS DE CARBURANT À GAZ DE PRÉMÉLANGE TOURBILLONNAIRE EN FLUX RADIAL

摘要

An injection system includes a radial swirler (102) defining an axis and including a plurality of radial swirl vanes (104) configured to direct a radially inward flow of compressor discharge air entering swirler inlets (108) between the radial swirl vanes in a swirling direction around the axis. The radial swirler includes an outlet (110) oriented in an axial direction to direct swirling compressor discharge air in an axial direction. An injector ring (114, 116, 118) is included radially outward from of the swirler inlets. The fuel injector ring is aligned with the axis and includes a plurality of injection orifices (120) directed towards the swirler inlets for injecting fuel into the radial swirler.
