摘　　要：介绍预转化催化剂失效对合成氨装置预转化炉、转化炉及换热盘管的影响。通过采取减负荷、旁路阀调节温度、减少转化炉燃料气量、调整风门及烧嘴背压、提高水碳比、增加盘管介质流通、减少转化炉烟气量等一系列的调节措施,将更换预转化催化剂的时间延长至检修期,确保了装置的安全、稳定运行。Introduce the effect of the failure of the pre-reforming catalyst on the pre-reforming furnace,the reforming furnace and the heat exchange coil of the ammonia plant.A series of adjustment measures such as increasing the water-to-carbon ratio,increasing the circulation of the coil medium,and reducing the amount of flue gas in the reformer will extend the time for replacing the pre-reforming catalyst to the maintenance period,ensuring the safe and stable operation of the device.
