摘　　要：针对1.3 t/d玄武岩池窑进行数值模拟,建立纯氧燃烧池窑火焰空间和玄武岩玻璃液流动空间的三维数学模型,利用fluent软件对池窑窑炉系统及通路系统进行数值模拟,获取池窑内部空间的速度场及温度场。通过与现场实测数据进行对比分析,最大偏差小于8%,说明该数学模型能够比较客观的反映玄武岩池窑窑炉及通路空间温度场、速度场分布规律,这对了解窑炉工作原理、改善工况以及优化窑炉设计都具有一定指导意义。The numerical simulation for a 1.3 ton per day basalt fiber furnace was made by building a three-dimensional mathematical model of oxy-fuel combustion space and molten basalt flow space in the basalt fiber furnace.The velocity field and temperature field inside the furnace were obtained by numerical simulation of the basalt furnace system and the forehearth system with FLUENT software.By comparing the simulation results with the on-site measured data,the maximum deviation of the data was less than 8%,showing that the mathematical model could objectively reflect the distribution rules of the temperature field and velocity field in the space of the basalt furnace and the forehearths,which could give a reference for understanding the furnace working principle,improving the furnace working condition and optimizing the furnace design.
