It is an object of the present invention to provide a conduit structure for molten glass, whereby even if molten glass is flown for a long time through a double-pipe structure portion comprising an inner pipe and an outer pipe joined together, stress load is little. The present invention provides a double pipe structure comprising an inner pipe and an outer pipe, wherein a supporting rib is provided between the inner pipe and the outer pipe to bridge the inner pipe and the outer pipe; wherein the supporting rib has an inner straight portion joined with the outer face of the inner pipe so as to extend along the longitudinal direction of the inner pipe, an outer straight portion joined with the inner face of the outer pipe so as to extend along the longitudinal direction of the outer pipe, and a connecting wall portion extending from the inner straight portion to the outer straight portion to integrate them; and the supporting rib has a concave portion along each of one side edge of the connecting wall portion present between one side end portion of the inner straight portion and one side end portion of the outer straight portion, and the other side edge of the connecting wall portion present between the other side end portion of the inner straight portion and the other side end portion of the outer straight portion, and reaching both side end portions of the respective straight portions via rounded portions, and the supporting rib has projecting portions formed on respective ends of the inner straight portion and respective ends of the outer straight portion.

摘要:
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.
