FUEL PREMIXING MODULE FOR GAS TURBINE ENGINE COMBUSTOR

摘要

An apparatus for mixing gas and fuel comprises a premixer including a first axial inflow swirler having a first plurality of vanes. The premixer includes a housing having a longitudinal centerline and a plurality of spaced fueling passages that allow the discharge of fuel onto the first axial inflow swirler. The plurality of fueling passages are inclined at an acute angle with respect to said longitudinal centreline. The apparatus includes a pilot premixer including a fuel dispenser and a second axial inflow swirler having a second plurality of vanes. The second axial inflow swirler is disposed around at least a portion of the fuel dispenser, and the premixer is disposed around at least a portion of said pilot premixer.
