Abstract
A method facilitates washing a gas turbine engine combustor. The method comprises coupling a nozzle assembly against the combustor, wherein the nozzle assembly includes an inlet end, a discharge end, a hollow nozzle body extending therebetween, and a centerbody positioned within the nozzle body, coupling the nozzle assembly to a fluid source, and discharging an annulus of fluid from the nozzle assembly into the combustor to facilitate removing particulate matter from the combustor.
Claims20
A method for washing a gas turbine engine combustor, said method comprising:
- coupling a nozzle assembly against the combustor, wherein the nozzle assembly includes an inlet end, a discharge end, a hollow nozzle body extending therebetween, and a centerbody positioned within the nozzle body;
- coupling the nozzle assembly to a fluid source;
- and
- discharging an annulus of fluid from the nozzle assembly into the combustor to facilitate removing particulate matter from the combustor.
A nozzle assembly for directing fluid into a gas turbine engine combustor for removing particulate matter from the combustor, said nozzle assembly comprising:
- a nozzle body extending between an inlet end and a discharge end, said body defining a cavity therein;
- and
- a centerbody positioned within said body such that an annular gap is defined between said centerbody and said nozzle body, said gap is segmented, said centerbody configured to couple said nozzle assembly to the combustor, said nozzle assembly for discharging an annulus of fluid through said gap into the combustor.
A method for washing a gas turbine engine combustor including an air swirler, and a deflector-flare cone assembly that extends circumferentially around the swirler, said method comprising:
- coupling a nozzle assembly to the deflector-flare cone assembly, wherein the nozzle assembly includes an inlet end, a discharge end, a hollow nozzle body extending therebetween, and a centerbody positioned within the nozzle body;
- coupling the nozzle assembly inlet end to a fluid source;
- and
- discharging fluid in an upstream direction from the nozzle assembly into the combustor to facilitate removing particulate matter from the combustor.
