摘 要:为了解决KDFM-NWT蒸汽发生器在设备启停时出现蒸汽倒灌的问题,对KDFM-NWT蒸汽发生器蒸汽管路进行了分析和改进。通过改造管路并设计法兰来加装逆止阀,实现停机时可以自动关闭回收管路,关断蒸汽回流,从而减少蒸汽倒灌现象发生。结果表明,蒸汽发生器改造完成后的3个月,KDFM-NWT蒸汽倒灌次数由8次减少到0次,由蒸汽倒灌引发的平均停机次数由4次/月降低到0次/月,有效提高了KDFM-NWT的工作效率,从而保证了设备的安全性。In order to solve the problem of steam backflow in the KDFM-NWT steam generator when the equipment is started and stopped,the steam pipeline of the KDFM-NWT steam generator was analyzed and improved.By modifying the pipeline and designing the flange to install a check valve,the recovery pipeline can be automatically closed during shutdown,thereby cutting off the return of steam and reducing the occurrence of steam backflow.The results show that:Three months after the completion of the steam generator transformation,the number of KDFM-NWT steam backflows was reduced from 8 times to 0 times,and the average number of shutdowns caused by steam backflow was reduced from 4 times/month to 0 times/month,effectively improving It improves the working efficiency of KDFM-NWT and ensures the safety of the equipment.
