摘要
根据阳极焙烧炉稳态模拟结果,对比原始方案与两种优化方案。以现场测试的热工参数和实验室测定的材料属性作为数值模拟的边界条件和物性参数,采用CFD模拟软件耦合求解了阳极焙烧炉火道、火道墙和料箱的温度场,获得了三个温度监测点的温升曲线。研究表明,改变火道内拉砖结构与减小火道墙厚度都可以加快阳极块达到标准焙烧温度,其中方案二的结果最为理想。此项设计对改进阳极质量和提高产量具有重要意义。
According to the result of steady - state simulation of anode baking furnace, one original scheme and two optimization schemes for the structure of furnace were compared and thermal parameters on site and material properties tested in the laboratory were taken as boundary conditions and physical parameters for numerical simulation, then CFD software was used to simulate coupling temperature filed of flue, flue wall and pit, finally the temperature rising curves of three temperature monitoring points were obtained. The results showed that the baking temperature of anode blocks could be speeded up to standard baking temperature by improving the structure of flue and thinning the flue wall, the second one of three schemes was the best, which was of the great significance for improving anode quality and productivity.
