具有良好运行特性的新型池窑结构设计

传统池窑中玻璃液的流动是自然对流控制下的混合对流，流型靠温度制度建立，稳定性差，对控制的要求高。为了改善玻璃熔制质量，剖析了传统池赛结构与运行特性的缺陷，针对性地提出了一种能克服其缺陷的新型池赛结构。用数值模拟对新池窑和传统池窑的运行特性进行了分析比较。这种新型池窑将澄清部由原来的深池改为浅槽，从而可用强迫流动取代原来的混合对流组织玻璃液澄清，因而具有稳定性好，易控制等优点。

Structure design of a new type tank furnace with better operation performances

The flow of glass melt in the traditional tank furnace is a kind of mixed convection dominated by natural convection. The flow pattern established by controling the temperature distribution has lower stability, and needs very high level control technique. In order to improve the glass fusion quality, the author anlysed the defects of the traditional tank furnace, and directing against these, proposed a new glass tank furnace structure which could overcome the shortcomings of the traditional one. The operation performances of the new type fornace are compared with the traditional one by using numerical simulation. In this new type furnace, the glass melt refining is performed by means of the forced flow instead of the original mixed convection, which has some advantages over the traditional furnace, such as higher stability, easier control.
