| 摘要 |
<p>The invention relates to a method and a device for preparing a final glass, that comprises a main furnace (1) with aerial burners and/or electrodes, supplied with main vitrification materials and generating a main molten glass, and a submerged combustion auxiliary furnace (2), said auxiliary furnace being supplied with auxiliary vitrification materials, the auxiliary molten glass being fed into the main furnace upstream thereof in the first third (12) of its length, and the auxiliary glass having substantially the same composition as the main glass. The downstream area of the main furnace is thus used for removing the gases from the main glass and the gases from the auxiliary glass, in order to completely melt down the non-molten material and the impurity contained in the auxiliary glass and in order to homogenise the two glass flows from the redox point of view when necessary.</p> |
