Abstract

Un procédé de préparation d'un bain de fusion pour la production de laine minérale consiste à chauffer le matériau brut pour la fonte dans un four à cuve par combustion de coke, tout en introduisant de l'air contenant de l'oxygène à travers les tuyères du four à cuve, et à obtenir une partie de la chaleur nécessaire par l'introduction et la combustion d'un mélange d'oxygène et de combustible dans la partie centrale du four à cuve. Un four à cuve permettant de réaliser ledit procédé comprend un tuyau de brûleur permettant d'introduire et de brûler un mélange d'oxygène et de combustible dans la partie centrale de la chambre du four.
