Abstract

L'invention porte sur un système de commande de combustion (100) pour un système de combustion (7) ayant une pluralité de tuyaux d'alimentation (5). Le système de commande de combustion (100) comprend une pluralité de débitmètres (10), un dispositif de commande (8), des commandes d'écoulement de combustible (11) et des commandes d'air secondaire (61, 62, 72). Chaque débitmètre (10) est conçu pour surveiller un écoulement de combustible à l'intérieur d'un tuyau respectif parmi les tuyaux d'alimentation (5) en détectant un champ de pression à l'intérieur du tuyau d'alimentation (5). Un dispositif de commande (8) reçoit les informations d'écoulement à partir de chacun des débitmètres (10), pour évaluer l'efficacité du système de combustion (7). Un dispositif de commande (8) fournit également des informations de commande pour commander l'écoulement des registres d'air secondaire (61, 62, 71), dans le système de combustion (7), et pour commander facultativement l'écoulement de combustible dans chaque tuyau d'alimentation (5).
