锅炉水汽系统一、二次网腐蚀问题的分析与解决

Analysis and solution examples for the first and second network corrosion of boiler water gas system

锅炉的"红水问题"是由于炉水对锅炉本体及系统设备的腐蚀造成的,其不仅会使凝结水无法回用,造成大量的补充水和能源的损失,还会对锅炉本身、后续相关系统的设备造成损坏,甚至对相关操作人员的安全都造成威胁。从一次网和二次网的腐蚀原因入手,通过分析分别找到各自系统存在的问题,提出解决方案,现场应用时收到了良好的效果。

The ＂red water＂ problem of boilers is caused by the corrosion effect of the boiler water on the boiler body and the equipment of the system. Because of the corrosion, the condensation water cannot be reused, which results in the great loss to make-up water and energy. The corrosion also damages the boiler as well as the follow-up system equipment, or even threatens the safety of the related operating personnel. Starting from the mechanism of the first and second network corrosion, and by way of analysis, the problems in each system have been found out, and solu- tions which were put forward and applied to worksites have received good effects.
