锅炉化学清洗主要包括酸洗和钝化两个过程,酸洗过程中传统的腐蚀速度测定方法是在系统内挂指示片,待酸洗结束后,通过失重测量才能确定基体金属的腐蚀速度,钝化效果的评价主要是目测法和钝化后取锅炉管样采用硫酸铜点滴实验法.这些检测方法都是对酸洗结果的评价,其局限性在于无法提供酸洗过程中所清洗设备的腐蚀速度、钝化状 The chemical cleaning of the boiler mainly includes two processes of pickling and passivation. The traditional method of measuring the corrosion rate during the pickling is to hang the indicator film in the system. After the pickling is finished, the corrosion rate of the base metal can be determined through the weight loss measurement. The evaluation of the effect is mainly the visual method and after passivation boiler tube sample using copper sulfate drip test method of these tests are pickled results evaluation, the limitation lies in the inability to provide corrosion during cleaning pickling equipment Speed, passivation-like
