Abstract
Systems and methods for operating a turbine engine having a plurality of fuel injectors arranged circumferentially in a combustor, with each fuel injector having a main fuel supply and a pilot fuel supply, includes supplying fuel to the plurality of fuel injectors through the main fuel supply to create a circumferential thermal gradient in the combustor.
Claims20
A method for operating a turbine engine having a plurality of fuel injectors arranged circumferentially in a combustor, each fuel injector having a main fuel supply and a pilot fuel supply, the method comprising:
- supplying fuel to the plurality of fuel injectors through the main fuel supply to create a circumferential thermal gradient in the combustor.
A method for operating a turbine engine having multiple fuel injectors arranged circumferentially in a combustor, each fuel injector having a main fuel supply and a pilot fuel supply, the method comprising:
- supplying a first quantity of main fuel to a first plurality of fuel injectors of the multiple fuel injectors;
- and
- supplying a second quantity of main fuel lower than the first quantity to a second plurality of fuel injectors of the multiple fuel injectors.
A method for operating a turbine engine having a plurality of fuel injectors arranged circumferentially in a combustor, each fuel injector having a main fuel supply and a pilot fuel supply, the method comprising:
- directing main fuel to the plurality of fuel injectors from a common fuel supply;
- directing a first quantity of the main fuel to a first set of fuel injectors;
- and
- passing the main fuel through a restriction device to direct a second quantity of main fuel lower than the first quantity to a second set of fuel injectors.
The method of claim 20, wherein the first set and the second set of fuel injectors are alternating pairs of fuel injectors.
