针对国内直接空冷机组空冷系统日益突出的腐蚀问题,通过工业实验确定了一种有效的加药方式和加药浓度,明显地抑制了直接空冷系统的运行腐蚀,获得了较好的技术经济效益。 Aiming at the increasingly prominent corrosion problem of the air-cooling system in domestic direct air-cooled units, an effective dosing method and dosing concentration were determined through industrial experiments. The corrosion of the direct air cooling system was obviously suppressed and the technical and economic benefits were obtained.
