某钢厂小型内燃式热风炉采用霍戈文矩形燃烧器,在烧炉过程中出现明显的震动现象。利用计算机仿真技术,对该热风炉燃烧特性进行模拟研究,通过分析燃烧过程中流场与温度场的分布,发现热风炉震动原因是燃烧器两侧在烧炉过程中回流过大、出现低频震动引起。对燃烧器结构进行优化后,震动减少。 A small steel internal combustion stove using the Hogwarts Rectangular burner, in the process of burning furnace obvious vibration phenomenon. By using computer simulation technology, the combustion characteristics of the hot blast stove were simulated. By analyzing the distribution of the flow field and the temperature field in the combustion process, it was found that the vibration of the hot blast stove was caused by the excessive backflow of the burners on both sides of the burner in the process of low frequency vibration cause. After the burner structure is optimized, the vibration is reduced.
