锅炉监察工作的目的是及时发现火电厂锅炉、压力容器、压力管道的安全隐患，防止承压部件发生爆破事故。锅炉化学监督的主要任务就是防止水、汽系统中金属材料的腐蚀、结垢和积盐，从而保证锅炉安全、经济运行。也就是要保证进入锅炉的水、汽品质能够满足其安全的需要，避免因介质因素对这些设备造成危害。热力设备的腐蚀有时是一个缓慢的过程，腐蚀的开始阶段一般不会直接威胁到设备的安全运行，如果人们对此不注意，任其发展，以至造成严重的后果。但有时腐蚀发展很快，例如某电厂新投产的锅炉投运不足2个月就发生大面积腐蚀并多次爆管，不得不更换大量的水冷壁管。因此，锅监工程师应时刻注意腐蚀、结垢和积盐等影响安全的苗头，及时采取措施或提醒化学人员采取措施，不然会造成严重后果。通过对本教材的学习，可系统、概要地掌握化学监督的有关知识，指导你所管辖的锅炉更安全、更经济地运行。本教材从火电厂水处理的基础知识着手，介绍了如何防止杂质进入锅炉，如何正确选择锅炉给水、炉水的处理方式，最大限度地防止热力设备在运行期间发生腐蚀、结垢和积盐，以及如何选用停用保护方法，防止发生停用腐蚀，使锅监工程师对锅炉、压力容器等安全运行能真正起到监督和指导作用。森达热电建湖公司彭海金······························································································································1第一节火电厂水处理的作用··························································································································1第二节火电厂中水的分类······························································································································1第三节火电厂中的水处理······························································································································1··································································································3第一节金属腐蚀简介······································································································································3第二节运行期间给水系统的腐蚀及防止······································································································4第三节炉水系统金属的腐蚀与防止··············································································································6第四节蒸汽系统的防腐与防积盐··················································································································7····························································································12第一节停用腐蚀············································································································································12第二节停用保护···········
