Abstract: An apparatus for the production of a mineral melt burns combustible material in the presence of inorganic material to form a melt. The apparatus includes a circulating combustion chamber which receives a fuel, pre-heated mineral material and a combustion gas so as to melt the mineral material and generate exhaust gases which are separated from the melt. The gases pass through an exhaust pipe to a conduit of a heat exchange system. The apparatus includes a quenching hood for quenching the exhaust gases by drafting a cooling fluid, such as ambient air, into the flow of exhaust gases around the exhaust pipe, and wherein the exhaust gases exit the exhaust pipe inside the hood.

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 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.
