摘要
运用物理模拟技术,系统研究了鼓泡前后玻璃窑内温度变化规律。结果表明:在加热条件相同的前提下,鼓泡使液面、加料口、澄清区以及热点处的温度发生了明显的变化。池底温度整体提高要求使用优质的材料。鼓泡位置以选在距加料口为窑长的2/5处较适宜,而鼓泡后窑内液流量不能无节制地增长。
The temperature distribution in a glass-melting tank with or without air bubblers was studied with the physical simulation technique. The results show that: under same heating condition, air bubbling makes an obvious chanse to the temperature at free surface, doghouse, refining section and hot spot; the tank bottom temperature has an integral rise, high-quality refractory is required; the suitable position for air bubbler is at a distance of 2/5 the furnace length; when air bubbling is used. the glass flow rate can not increase béyond the limit.
