| 摘 要： | 大唐三门峡发电有限责任公司的3#机组给水早期采用还原性全挥发处理方式,存在流动加速腐蚀,机组投运不到2年,水冷壁垢量就接近化学清洗标准,现在改用给水加氧处理技术.介绍给水加氧处理技术,分析应用效果.与还原性全挥发处理方式比较,加氧处理技术具有锅炉受热面结垢速率低、化学清洗周期短、精处理混床运行周期长、自用水率低以及化学加药量小等优点,提高了机组运行的经济性和安全性.

| Abstract: | The feed-water all volatile treatment(AVT) was applied in the generator unit 3 of Datang Sanmenxia Power Plant Co.Ltd.The generator operated less than two years,the scale quantity of water-wall tubes was close to the limiting values of China Chemical Cleaning Standard due to flow-accelerated corrosion(FAC).In order to improve it,the feed-water oxygenated treatment(OT) is currently used.The OT technology is introduced and its application results are analyzed in this paper.OT has several advantages over AVT,e... |
