搞好水质处理工作是保证锅炉安全经济运行的重要措施。而做好水处理工作的前提,应首先确定锅炉水处理的方式。对于工业锅炉,通常是选用钠离子交换的方法,除去原水中的硬度物质。原水经钠离子交换后,水的硬度下降,碱度不变、含盐量略有增加。电站锅炉的蒸汽品质要求高,所以其给水应是除盐水,才能达到锅炉和汽轮机的使用要求。但是除盐水的制水成本较高,除电站锅炉外,一 Improving water quality is an important measure to ensure the safe and economical operation of boilers. The premise of doing a good job of water treatment, water treatment should first determine the way the boiler. For industrial boilers, sodium ion exchange is usually used to remove raw water hardness. Raw water after sodium ion exchange, water hardness decreased, alkalinity unchanged, slightly increased salt content. Power station boiler steam quality requirements, so the water supply should be desalinated water, in order to achieve the boiler and turbine requirements. However, the demineralized water is more expensive to produce water, in addition to the power station boiler, one
