| 摘 要： | 某300kt／a合成氨装置一段转化炉投产后曾先后三次发生转化管爆管故障，为判断故障原因，针对实际生产运行中不同的操作工况进行了模拟计算，并根据计算结果进行了不同操作工况下转化炉性能分析。指出该炉存在的一些问题，提出了以下优化改进意见：操作中应注意合理调节各排燃烧器的供热比例，适当降低炉膛底部两排燃烧器的供热量，增加中间两排燃烧器的供热量，为防止烟气温度过高，可适当降低顶部燃烧器的供热量；尽量点燃所有燃烧器，保证每排燃烧器中每个燃烧器能量相同；保证每个燃烧器的火焰喷出部位都超过燃烧器砖的表面；提高预转化系统的在线率；注意转化管供热和吸热的匹配，严格杜绝炉管“干烧”现象。

| Abstract: | The tubes of the 1st-stage reforming furnace in a 300,000 ammonia synthesis plant ruptured 3 times after it was first put into operation.In order to locate the root causes of the accidents,simulation calculations have been made based upon different operating conditions in plant operation,and reforming furnace performances under different operating conditions are analyzed based upon the calculation results.To solve the problems of the reforming furnace found in the analysis,the following improvements are pro... |
