【摘要】 应用模型试验的方法,研究窑池深浅、机械搅拌以及与其它玻璃液分隔设备配合使用时,模型窑内温度场、速度场和液流分布情况,从而提出了浮法熔窑结构的改进和节能建议。 研究结果表明,降低冷却部的池深可提高降温效果,冷却部池深以1～1.2米为宜;卡脖处安装搅拌装置可提高玻璃液的热均匀性,并能降低冷却部温度;联合装置比只有浅池或搅拌单项装置时降温效果好,浅池、卡脖缩小和双框搅拌器配合使用时,冷却降温作用最佳。更多还原

【Abstract】 A study on the depth of tank and mechanical stirring was made by means of physical modeling, and an investigation on temperature field, velocity field, and glass current distribution in the model tank with the application of physical modeling combined with other partition devices was also carried out. Some suggestions on the improvement of the construction of float glass tank furnace and on energy-saving have thus been proposed.The experimental results show that reduoing the depth of conditioning zone is effective on lowering the temperature in that area; a 1 to 1.2 M deep conditioning zone is appropriate; a stirrer mounted at neck can improve the heat distribution of molten glass and drop the temperature in conditioning zone; the combined device is more effective in lowering temperature than the device which has either shallow tank or stirrer only. When shallow tank and narrow neck are used together with a double-frame stirrer the optimum cooling result can be obtained.更多还原
