【摘要】 建立了具有实用意义的浮法玻璃熔窑三维数学模型,将火焰空间燃烧模型、配合料熔化模型、玻璃液流动模型进行耦合计算,求解出玻璃熔窑火焰空间、玻璃液流的温度场、速度场分布及配合料堆的长度分布。以日产400 t的燃天然气浮法玻璃熔窑为对象研究了其火焰空间内气体、窑池内玻璃液的流动情况及各自的温度场分布。从模拟结果可以看出,该三维耦合数学模型能够比较客观地反应燃天然气浮法玻璃熔窑的速度场和温度场的分布规律,对燃天然气浮法玻璃熔窑的设计和运行具有一定的实用价值。更多还原

【Abstract】 In this paper,a practical three-dimensional mathematical model of the floating glass furnace has been developed.The combustion chamber model,glass flow model and batch melting model are coupled together to calculate the distribution of the flow and temperature fields and the batch coverage.A floating glass furnace fired by natural gas,whose pull rate is 400 tons/day,was selected as the research object.The result shows that the coupled three-dimensional mathematical model can reflect the real distribution of the temperature and flow fields of the natural gas fired floating glass furnace,which will be practically significant in the design and operation of the furnace.更多还原
