摘要
氯离子对亚临界机组的腐蚀危害极大,其腐蚀表现形式主要是破坏水冷壁管金属表面的钝化膜,进而向金属晶格里面渗透,引起金属表面性质的变化。分析炉水系统中氯离子对金属腐蚀的现象,并针对炉水系统内部氯离子的来源,提出了相应的解决措施。
Chlorine ion has great corrosion harm on the subcritical generation units.The corrosion appears as the way of destroying the passivating membrane of the metal surface on the cooling water wall and penetrating into the metal grids,causing the performance variation of the metal surface.The paper analyzes the phenomenon of the metal corrosion by chlorine ion in boiler water,based on the resources of chlorine ion inside the boiler water system,puts forward the corresponding solutions.
