背景2007年,某中外合资汽车制造厂在中国华北地区新建一家工厂。该厂拥有约3000名员工,轿车年设计生产能力在300000辆以上。该厂综合性动力系统包括三台燃气锅炉和三套反渗透系统,全天候运行。根据设计方案,水处理系统仅使用化学除氧方法将溶解氧浓度控制在1ppm。问题该客户当时在锅炉运行方面遇到两个严重的问题——氧腐蚀和气蚀。氧腐蚀在锅炉的运行过程中,冷水吸收了氧气和其他气体,并在被加热后释放出来。为了防止锅炉和蒸汽设备腐蚀,必须除去这些溶解氧,
Background In 2007, a Chinese-foreign joint venture automobile factory built a new factory in North China. The plant has about 3,000 employees, car design production capacity in more than 300,000 vehicles. The plant’s integrated power system includes three gas boilers and three reverse osmosis systems that operate on a 24/7 basis. According to the design, the water treatment system uses only the chemical oxygen scavenging method to control the dissolved oxygen concentration at 1 ppm. Problem The customer then encountered two serious problems with boiler operation at that time - oxygen corrosion and cavitation. Oxygen Corrosion During the operation of a boiler, cold water absorbs oxygen and other gases and is released when heated. In order to prevent corrosion of boilers and steam equipment, these dissolved oxygen must be removed,
