Definitions
- the burner pipe is provided with a cooling jacket having a pipe stub 12 for the supply of cooling medium and a further pipe stub 13 for the discharge of spent cooling medium.
- the position of the lower end of the burner pipe 11 in the furnace chamber is adjustable, the burner pipe 11 being connected with mechanical or hydraulic 0 devices (not shown) for longitudinally displacing the burner pipe 11.
- the burner pipe shown in Fig. 2 comprises three more stubs 14, 15, and 16, the pipe stubs 14 and 15 serving to introduce oxygen and fuel respectively and the pipe stub

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.
