Title (EN) SYSTEM AND METHOD FOR OPERATING A COMBUSTION CHAMBER
(FR) SYSTÈME ET PROCÉDÉ PERMETTANT DE FAIRE FONCTIONNER UNE CHAMBRE DE COMBUSTION
Abstract:
(EN) 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.
(FR) L'invention concerne un procédé permettant de faire fonctionner une chambre de combustion. Le procédé comprend l'introduction d'un carburant dans la chambre de combustion par l'intermédiaire d'une pluralité de buses, chaque buse ayant une stœchiométrie associée concernant une extrémité de sortie de la buse. Le procédé comprend en outre la mesure de la stœchiométrie de chaque buse par l'intermédiaire d'un ou de plusieurs capteurs afin d'obtenir des données stœchiométriques et détermine qu'une fréquence et/ou une amplitude des fluctuations de raies spectrales dérivées des données stœchiométriques ont dépassé un seuil. Le procédé comprend en outre le réglage de la stœchiométrie d'au moins l'une des buses sur la base, au moins en partie, des données stœchiométriques de façon à maintenir une stabilité de flamme de la chambre de combustion.
