RGGN-400除氧器原理、运行及改造效果

Principle, operation and retrofit effect of RGGN-400 deaerator

除氧器的作用是除去溶于水的含氧,避免锅炉、汽轮机组各系统的金属部件在高温下发生过度的氧化腐蚀。氨醇车间除氧器因设计和安装、取样等原因,导致锅炉给水溶解氧不合格,通过对除氧器相关内件及附件进行改造,改造后给水溶解氧均合格,且改造费用低,时间短,效果好。

The function of deaerator is to remove oxygen dissolved in water, avoiding excessive oxidation corrosion of the metal parts of boiler and steam turbine systems at high temperatures. Deaerator in ammonia and alcohol plant has some problems of design,installation and sampling, so dissolved oxygen in boiler water is unqualified. By retrofitting internals and accessories of deaerator,dissolved oxygen is qualified. And the retrofit have characteristics of low cost, short time consuming and good effect.
