摘　　要：阳极焙烧炉火道内温度场的均匀性直接决定焙烧阳极的质量。传统“W”火道结构焙烧炉的火道内上、下游温差较大和料箱内温度分布不均匀以及天然气能耗较高。应用CFD软件进行数值模拟计算,研究了新型火道结构阳极焙烧炉火道内流场以及料箱内温度分布均衡性。新型火道结构焙烧炉在某炭素厂进行的工业试验测试表明:新型火道结构的焙烧炉明显改善了料箱内温度分布的均匀性进而提高了阳极质量。The quality of baked anode is directly determined by the uniformity of temperature field in the flue of the anode baking furnace. The temperature difference between the upstream and downstream of the traditional furnace with “W”flue structure is large, the temperature distribution in the pit is uneven, and the energy consumption of natural gas is high. The numerical simulation calculation is carried out with CFD, both the flow field in the flue and the temperature homogeneity in the pit of the anode baking furnace with new type flue structure are studied. The industrial test of the baking furnace with new type flue structure in a carbon plant showed that a more uniform temperature distribution is achieved and the quality of the baked anode is improved greatly in the baking furnace with new type flue structure.
