Abstract
A combustor includes a first combustion chamber, a pre-mixing primary fuel-nozzle assembly associated with the first combustion chamber, a second combustion chamber, and a secondary fuel-nozzle assembly associated with the second combustion chamber. The pre-mixing primary fuel-nozzle assembly includes a number of vanes configured to swirl airflow, each vane comprising a number of fuel injection holes configured to inject fuel into the airflow.
Claims20
A combustor, comprising:
- a first combustion chamber;
- a pre-mixing primary fuel-nozzle assembly associated with the first combustion chamber, the pre-mixing primary fuel-nozzle assembly comprising a plurality of vanes configured to swirl airflow, each vane comprising a plurality of fuel injection holes configured to inject fuel into the airflow;
- a second combustion chamber;
- and
- a secondary fuel-nozzle assembly associated with the second combustion chamber.
The combustor of claim 5, wherein the pre-mixing primary fuel-nozzle assembly is positioned in the first combustion chamber such that air flows through the pre-mixing primary fuel-nozzle assembly in a radially direction and fuel flows through the pre-mixing primary fuel-nozzle assembly in an axially direction.
A pre-mixing primary fuel-nozzle assembly, comprising:
- an inner annular collar comprising a plurality of air passage openings;
- a plurality of vanes extending radially outward from the inner annular collar;
- and
- a plurality of fuel injection holes formed in each vane.
A combustor, comprising:
- a first combustion chamber associated with a pre-mixing primary fuel-nozzle assembly;
- and
- a second combustion chamber associated with a secondary fuel-nozzle assembly;
- wherein the pre-mixing primary fuel-nozzle assembly is concentrically positioned about the secondary fuel-nozzle assembly.
