Abstract:
A dual stage vane pilot nozzle (100) has a non-diffusion nozzle (110) and a first fuel stage (121) and a second fuel stage (122). The first fuel stage (121) has a first fuel injector (101) having first injection holes (103) and a first fuel annulus (105). The second fuel stage (122) has a second fuel injector (102) having second injection holes (104) and a second fuel annulus (106). The non-diffusion (110) does not have a diffusion tip. This arrangement allows for the reduction of nitrogen oxide emissions.
