| 摘 要： | 目前超临界直流炉大都采用氧化性水工况,要求给水中铁的含量小于10 μg/L.为使超临界直流炉采用的氧化性水工况的腐蚀控制与铁-水体系的电位-pH图统一,不能再以10-6mol/L(即56μg/L)作为钢铁腐蚀与否的界限,而必须以10-6.75mol/L(即10μg/L)作为腐蚀发生与否的界限,绘制铁-水体系的简化电位-...

| Abstract: | The super-critical once through boiler adopts oxidative water condition presently,and it is required that the ferrum ion content in the supplied water should be lower than 10 μg/L.To unify the corrosion controlling of the oxidative water condition and the potential-pH chart of the ferrum-water system,it is considered that 10-6.75mol/L（namely 10 μg/L）is more reasonable than 10-6mol/L（namely 56 μg/L）to be the limit to judge the corrosion.At the same time,the potential-pH chart of ferrum-water system is drawn which ion content is chosen as 10-6.75mol/L（namely 10 μg/L）in the balance calculation. |
