| 摘要 |
The invention relates to a method and a device for preparing a glass having a low boron content and loaded with alumina or zirconia, the melting of the vitrification materials being carried out in an end-fired furnace provided with regenerators (4, 4i), the main portion of the fossil energy being introduced by the loop flame in which the oxidant and the fuel are introduced in the upstream side (1) of said furnace, the oxidant consisting of air or oxygen-enriched air. The melting compartment can be followed by a glass fibering unit. The invention can be used in the production of fibres having combustion yield and a high productivity. |
