9ASG除氧器的运行

9ASG deaerator operation

9ASG除氧器能为REA和ASG水箱提供除盐除氧水,虽然不是核安全相关设备,但是其可用性却是与核安全密切相关的。本文从9ASG除氧器的组成和功能出发,简要介绍了其包含的主要设备、供水水源及其供水方式。同时,通过阐述和分析9ASG除氧器的工作原理、工艺流程及其运行的5个工况(停运、升温、除氧、生产、氮气覆盖),使读者能够更充分的了解9ASG除氧器的运行方式,加之以9ASG除氧器的脱扣信号及其定值、历年主要技改项目、作者个人日常操作经验等,分析并总结出9ASG除氧器日常运行5个工况认为需要关注的事项,尤其是在启动除氧器向ASG/REA水箱制水前、制水期间、以及后续切换等操作的注意事项。

9ASG deaerator for REA and ASG provide the desalting deaerator water tank, although not the nuclear safety related equipment, but its availability is closely related with the nuclear safety. This article from the composition and function of 9ASG of the deaerator, briefly introduces its main equipment, including water supply and water supply mode. At the same time, through the elaboration and analysis of 5 working principle, 9ASG deaerator process and its operation (outage, temperature, oxygen, production, nitrogen coverage), so that readers can more fully understand 9ASG deaerator operation mode, in addition to the 9ASG deaerator release signal and its value, the main technical improvement the project, author's daily operating experience, analysis and summing up of the daily operation of 9ASG deaerator 5 conditions that matters need attention, especially the note in the deaerator water tank to start ASG/REA water before, during, and subsequent water switch operation.
