FREMGANGSMAATE FOR SMELTING AV PULVERFORMIG SATSMATERIALE. |
摘要 |
<p>Liquefying of pulverulent batch materials (e.g., glass batch) is carried out in two stages. The first stage (10) utilizes extended gas/solid contact to heat the materials to an intermediate temperature, and may recover waste heat. The second stage (12) rapidly liquefies the material in a cavity lined with the batch material, and may employ substantially nitrogen-free heat sources. Another aspect involves maintaining a wet condition in the first stage to entrap particulates.</p> |
