对于锅水品质会直接影响锅炉产生结垢和发生金属腐蚀的重要性,并没有引起锅炉运行操作人员和管理人员的重视。正像有个别的工厂负责人所说的:“这样清澈透明的水人都可以喝,锅炉还不能用吗?”虽然这只是个别现像,但它却代表了一部分人的思想方法以及对事物的认知程度。但最容易忽略锅水标准的则是采用锅外处理锅水的那些运行和管理人员,他们认为经锅外离子交换后给水的硬度已经达到标准的要求了,还会出问题吗?是的,只要对锅水的碱度和pH值不进行监督,当锅水的碱度和pH值超出标准的范围就要出问题。下面介绍4个实例来说明这个问题:1)在吉林省某化工厂,厂内有3台蒸发量为10t/h的水管锅炉,给水采用锅外离子交换法处理。所选
The quality of the pot water will have a direct impact on the boiler fouling and the importance of metal corrosion, and did not cause the boiler operator and management staff attention. Just as the heads of individual factories put it: “Such clear and transparent water can be drunk and the boiler can not be used yet.” Although this is only an isolated phenomenon, it represents a part of the people’s thinking method and The degree of awareness of things. But the easiest to ignore the standard pot is the use of pot outside the pot of those operating and management staff, they think that the water hardness after the ion exchange through the pot has reached the standard requirements, but also a problem? Yes, As long as the alkalinity and pH of the pot water are not supervised, problems arise when the alkalinity and pH of the pot water exceed the standard range. Here are four examples to illustrate this problem: 1) In a chemical plant in Jilin Province, there are 3 water-tube boilers with 10t / h evaporation, and the water is treated by ion exchange outside the pot.
