Process and glass melting furnace for producing high-temperature melting glasses having vapourisalbe components |
摘要 |
<p>A method for producing glasses with a high melting point and volatile components comprises: (a) supplying the combustion chamber (2) with a gas containing at least 50 vol. % oxygen, the temperature in the top furnace (4) is brought to at least 1600 [deg]C; (b) using a raised bottom section (15) consisting of a clarifying bed (17) with a preceding step (16) whose height is 0.3-0.7 times the height of the bed (17); (c) passing the melt (12) in front of the step (16) over at least one row of bubblers (21); and (d) after the step (16) - which is provided with at least one row of booster electrodes (22) - passing the highly heated melt over the horizontal clarifying bed (17). Also claimed is a corresponding furnace.</p> |
