The invention relates to a furnace for producing a melt for mineral wool production comprising a shaft (2) for preheating and melting of the raw material (6); a water-cooled grate (5) disposed in the bottom portion of the shaft, which supports a bed of ceramic filling bodies (4) as well as the raw material (6); a combustion chamber (3) disposed underneath the shaft (2), which has a bottom portion (11) for collecting the melt (14) dripping from the shaft (2) and an outlet (12) for melt tapping; and at least one main burner (9) disposed in the combustion chamber (3); as well as auxiliary burners (10) disposed above the grate (5). The bottom surface of the combustion chamber (3) is larger, preferably 20 to 400% larger than the cross area of the shaft (2). Fig. 1 |
