Abstract

Procédé et dispositif de régulation du débit d'air d'un pulvérisateur de charbon Le dispositif électronique comprend des organes émetteurs de signaux proportionnels respectivement à la température choisie, à la température effective, au débit choisi et au débit effectif. Le signal résultant d'écart de température règle le débit d'air chaud; le signal résultant d'écart de débit règle le débit d'air froid; et l'on peut modifier le signal de débit choisi en fonction de l'écart de température. Un signal de débit minimum détermine un second écart de débit, qui ouvre le registre d'air chaud si le débit mesuré devient inférieur au débit minimum. L'invention s'applique en particulier au réglage de l'alimentation des brûleurs d'un foyer à charbon pulvérisé.
