DUAL FUEL NOZZLE WITH LIQUID FILMING ATOMIZATION FOR A GAS TURBINE ENGINE
A fuel nozzle for a combustor of a gas turbine engine includes an outer air swirler along an axis, said outer air swirler defines an outer annular air passage between an outer wall and an inner wall, the outer wall defines a convergent-divergent nozzle. An inner air swirler along the axis to define...

| description | A fuel nozzle for a combustor of a gas turbine engine includes an outer air swirler along an axis, said outer air swirler defines an outer annular air passage between an outer wall and an inner wall, the outer wall defines a convergent-divergent nozzle. An inner air swirler along the axis to define an annular liquid passage therebetween, the annular liquid passage terminates upstream of the convergent-divergent nozzle and an annular fuel gas passage around the axis between the outer air swirler and the inner air swirler.
La présente invention concerne un gicleur de combustible pour une chambre de combustion d'une turbine à gaz, ledit gicleur comprenant un tourbillonneur d'air externe le long d'un axe, ledit tourbillonneur d'air externe définissant un passage d'air annulaire externe entre une paroi externe et une paroi interne, la paroi externe définissant un gicleur convergent-divergent. L'invention comprend un tourbillonneur d'air interne le long de l'axe pour définir un passage liquide annulaire entre eux, le passage liquide annulaire se terminant en amont du gicleur convergent-divergent et un passage de gaz combustible annulaire autour de l'axe entre le tourbillonneur d'air externe et le tourbillonneur d'air interne. |
