Abstract
A method for operating a combustion chamber is provided. The method includes introducing a fuel into the combustion chamber via a plurality of nozzles, each nozzle having an associated stoichiometry for an output end of the nozzle. The method further includes measuring the stoichiometry of each nozzle via one or more sensors to obtain stoichiometric data, and determining that at least one of a frequency and an amplitude of spectral line fluctuations derived from the stoichiometric data has exceeded a threshold. The method further includes adjusting the stoichiometry of at least one of the nozzles based at least in part on the stoichiometric data so as to maintain a flame stability of the combustion chamber.

A method for operating a combustion chamber comprising:
- introducing a fuel into the combustion chamber via a plurality of nozzles, each nozzle having an associated stoichiometry for an output end of the nozzle;
- measuring the stoichiometry of each nozzle via one or more sensors to obtain stoichiometric data;
- determining that at least one of a frequency and an amplitude of spectral line fluctuations derived from the stoichiometric data has exceeded a threshold;
- and
- adjusting the stoichiometry of at least one of the nozzles based at least in part on the stoichiometric data so as to maintain a flame stability of the combustion chamber.
A system for operating a combustion chamber comprising:
- a plurality of nozzles operative to introduce a fuel into the combustion chamber;
- one or more sensors operative to obtain stoichiometric data via measuring a stoichiometry associated with an output end of at least one of the nozzles;
- a controller in electronic communication with the nozzles and the one or more sensors;
- and
- wherein the controller is operative to:
