Abstract

Le four est du type comportant, à une extrémité 13, un brûleur principal 3 disposé au-dessus d'un carneau d'évacuation et dirige vers l'autre extrémité 14 du four, de sorte que le flux de chaleur suit un trajet en U, et un brûleur auxiliaire 4 disposé au-dessous du brûleur principal. Des pyromètres 15, 16 sont montés dans les deux parois d'extrémité 13, 14 et des moyens de commande comparent leurs signaux pour commander le rapport de poussée entre les deux brûleurs en fonction de tout écart de température d'une extrémité à l'autre du four de façon à réduire cet écart à zéro ou à une faible valeur choisie.
