Abstract: A melt for use in the production of man-made vitreous fibres may be formed in a circulating combustion chamber (20) by melting particulate material. The material is collected in a base region of the combustion chamber (26), where it can be heated using submerged combustion apparatus (40). The submerged combustion process is controlled to ensure that the proportion of Fe(2+) based on total Fe within the melt extracted from an outlet of the chamber is greater than 80%.

Abstract: A melt for use in the production of man-made vitreous fibres may be formed in a circulating combustion chamber (20) by melting particulate material. The material is collected in a base region (26) of the combustion chamber, where it can be heated using submerged heating means (40). The submerged heating increases the homogeneity of the melt within the melt pool (30), the increase in homogeneity being encouraged by a relatively long average residence time for mineral material in the chamber (20) of at least 15 minutes.

The material is collected in a base region of the combustion chamber (26), where it can be heated using submerged heating means (40). The submerged heating increases the homogeneity of the melt within the melt pool (30), the coherence of which is maintained by the use of a siphon (50) to extract melt from the combustion chamber.
