Abstract
A nozzle includes a center body and a shroud circumferentially surrounding at least a portion of the center body to define an annular passage between the center body and the shroud. The nozzle further includes a bimetallic guide between the center body and the shroud. A method for supplying fuel to a combustor includes flowing a working fluid through a nozzle, injecting the fuel into the nozzle, and mixing the fuel with the working fluid to create a fuel and working fluid mixture. The method further includes swirling the fuel and working fluid mixture, sensing flame holding in the nozzle, and reducing the swirl in the fuel and working fluid mixture.
Claims20
A fuel nozzle, comprising:
- a. a center body;
- b. a shroud circumferentially surrounding at least a portion of the center body to define an annular passage between the center body and the shroud;
- and
- c. a bimetallic guide between the center body and the shroud.
A combustor, comprising:
- a. an end cap;
- b. a fuel nozzle disposed in the end cap, wherein the nozzle includes:
- i. a shroud, wherein the shroud defines an annular passage in the nozzle;
- and
- ii. a bimetallic guide disposed in the annular passage.
A method for supplying fuel to a combustor, comprising:
- a. flowing a working fluid through a nozzle;
