Abstract
A method and apparatus for controlling a flame stability at a gas turbine generator is disclosed. The method includes forming combustible mixtures at a plurality of fuel nozzles of a combustor of the gas turbine generator; altering an oxygen concentration of at least one of the combustible mixtures at a selected fuel nozzle of the plurality of fuel nozzles; and burning the combustible mixtures at the plurality of fuel nozzles to control the flame stability at the gas turbine generator.

A method of controlling a flame stability at a gas turbine generator, comprising:
- forming combustible mixtures at a plurality of fuel nozzles of a combustor of the gas turbine generator;
- altering an oxygen concentration of at least one of the combustible mixtures at a selected fuel nozzle of the plurality of fuel nozzles;
- and
- burning the combustible mixtures at the plurality of fuel nozzles to control the flame stability at the gas turbine generator.
An apparatus for controlling a flame stability of a gas turbine generator, comprising:
- a plurality of fuel nozzles of a combustion chamber at the gas turbine generator configured to form a plurality of combustible mixtures;
- and
- a flow element configured to alter an oxygen concentration of a combustible mixture at a selected fuel nozzle of the plurality of fuel nozzles to control the flame stability of a flame resulting from burning the combustible mixtures.
A gas turbine generator, comprising:
- a combustor having a plurality of fuel nozzles configured to form combustible mixtures for burning in the combustor;
- and
- at least one flow element configured to alter an oxygen concentration of a combustible mixture at at least one of the plurality of fuel nozzles to be different from an oxygen concentration of the combustible mixtures at the other of the plurality of fuel nozzles, wherein the combustor produces substantially a same emission level burning the combustible mixtures having the different oxygen concentrations as when burning combustible mixtures having substantially a same oxygen concentration.
