摘　　要：针对某玻璃纤维厂年产2万t玻璃纤维窑炉进行数值模拟,建立关于全氧燃烧玻璃纤维窑炉中火焰空间和玻璃液流动的三维数学模型,运用UDF程序将两部分通过单向耦合的方式有机结合并获得模拟结果.通过模拟结果与现场实测数据进行比较可以看出,该数学模型能够比较客观的反映单元玻璃纤维窑炉富氧燃烧空间和温度场、速度场的分布规律.这对了解玻璃纤维窑炉工作原理、改善工况、降低风险以及优化窑炉设计都具有一定指导意义.A three-dimensional mathematical model of oxygen-fuel combustion space and glass fluid flow was established in this paper,according to the practical situation of a fiberglass furnace whose production is up to 20000 ton per year.Simulation results were obtained by using UDF program to combine two parts through the one-way couple.Based on the comparison between the simulation and the measured results obtained on the spot,it can be suggested that the mathematical model can well reflect the real distribution of the temperature field and velocity field of oxygen-enriched combustion and glass tank in fiberglass furnace.The studies here will be really useful for understanding the furnace works,improving the working conditions,reducing the risks,and optimizing the designs of glass furnace.
