Abstract
Dispositif permettant de détecter des défauts dans le système de combustion à un stade précoce. Il comprend un calculateur numérique 70, un circuit d'entrée 72 fournissant des signaux indicatifs des températures détectées par un détecteur de température choisi 50, et un circuit 74 pour choisir le détecteur de température à échantillonner, le calculateur numérique étant programmé pour échantillonner successivement les détecteurs de température du courant de gaz chauds et déterminer la température médiane, calculer des limites admissibles de température en fonction de cette température médiane et de la température de décharge du compresseur et émettre un signal d'arrêt ou d'alarme si un nombre prédéterminé de détecteurs de température du courant de gaz chauds dépasse les limites admissibles suivant un schéma prédéterminé. Application aux turbines à gaz.Device for detecting faults in the combustion system at an early stage. It comprises a digital computer 70, an input circuit 72 supplying signals indicative of the temperatures detected by a selected temperature detector 50, and a circuit 74 for choosing the temperature detector to be sampled, the digital computer being programmed to successively sample the temperature. hot gas stream temperature detectors and determine the median temperature, calculate allowable temperature limits based on this median temperature and the compressor discharge temperature and issue a shutdown or alarm signal if a predetermined number of Hot gas stream temperature detectors exceed allowable limits according to a predetermined scheme. Application to gas turbines.
