摘要

燃料不换向型蓄热燃烧器因其故障率低、工作稳定且投资较少而适用于旧炉余热回收改造。蓄热燃烧器的喷嘴结构、尺寸对炉膛的温度、燃烧的效果影响很大。对蓄热燃烧器进行了理论设计,并使用Fluent软件,对喷嘴在不同工况下进行了数值模拟,得出结论为:对某型锻造加热炉,燃烧器的空气喷嘴和燃气喷嘴最优夹角为15°,上下空气喷嘴之间的最佳距离为0.7 m。
        Regenerative burner without changing the direction of fuel was used for the old furnace waste heat reclamation because of its low failure rate, stable operation and less investment. The structure and size of regenerative burner nozzle had large influence on temperature of furnace and burning effect. The regenerative burner was theoretically designed. The nozzles under different conditions were numerically simulated with the Fluent software. The conclusion is that: for a certain type of forging heating furnace, the best angle between the air nozzle and the fuel nozzle is 15°, the best distance between air nozzles is 0.7 m.
