摘要
对36室敞开式环式焙烧炉焙烧过程中有代表性的火道和料箱三维空间中不同位置的动态温度变化参数进行了测试和深入分析。测试结果表明,焙烧过程中低温及中温阶段升温速率较慢,尤其边部火道升温速率低于中间火道,温度分布不均匀,造成挥发分析出时间过长,挥发分燃烧不完全现象严重。在对动态温度参数深入分析的基础上,提出了优化焙烧工艺、提高焙烧过程中燃料和挥发分的燃烧能量利用率的建议,用于焙烧实践,实现阳极焙烧过程中的节能降耗。
The operation parameters of 36-room ring type anode baking furnace,such as the heating curve in different position of flue and anode during the baking process,were measured and analyzed.The results showed that the heating rate in the low and medium temperature range was too slow,while the distribution of the temperature in the anode was uneven,which hindered the improvement in the anode quality.The much lower heating rate of the anode resulted in the much longer time of the volatiles evolution,accompanied with the low content of oxygen in the flue,the combustion of the volatiles and the gas fuel was not sufficient.Based on the analysis of the measuring results,some effective advices were proposed to be applied in practice,in order to optimize the baking process and improve the volatiles and fuel combustion efficiency,help the industry to save energy and reduce cost.
