Abstract

L'invention concerne un dispositif pour commander le processus de combustion dans une installation de combustion d'une centrale pourvue de brûleurs (1) agencés dans une paroi d'un foyer. L'amenée de l'air de combustion s'effectue par une fente annulaire (3) entourant le brûleur (1) et le brûleur (1) comprend des moyens destinés à agir sur la quantité d'air de combustion circulant à travers la fente annulaire (3). Le dispositif comprend des moyens destinés à détecter la quantité de combustible amenée à un brûleur (1) et des moyens destinés à déterminer la quantité d'air de combustion circulant à travers la fente annulaire (3). Les moyens destinés à déterminer la quantité d'air de combustion circulant à travers la fente annulaire (3) comportent deux barres de détection (11, 12) formant une paire correspondante, qui sont agencées l'une derrière l'autre et parallèlement l'une à l'autre dans la fente annulaire (3.1) de préférence transversalement à l'axe longitudinal (4) de la fente annulaire et dans le sens d'écoulement (7) du moteur à combustion interne. L'agencement des barres de détection (11, 12) s'effectue de telle sorte qu'au moins une partie de l'air de combustion circulant le long de la première barre de détection (12) dans le sens d'écoulement (7) du flux d'air de combustion circule également le long de la deuxième barre de détection (11) dans le sens d'écoulement (7) du flux d'air de combustion. Les barres de détection (11, 12) sont reliées électriquement à un dispositif de mesure de corrélation (13) permettant de déterminer la vitesse du flux d'air de combustion en évaluant les signaux électriques produits par influence électrique, et de définir la quantité d'air de combustion circulant à travers la fente annulaire (3.1) sur la base de la surface de section transversale de la fente annulaire (3.1). Le processus de combustion est commandé de manière correspondante par modification de la quantité d'air de combustion.
