Abstract

See full text

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.
