结合多年工作经验,并参考了大量文献资料,阐述了工业锅炉用水的一般水质指标,分析了锅炉水质不良对工业锅炉造成的危害,并提出了防护对策.锅炉的给水,基本上都是用城市自来水.因为绝对纯净的水是没有的,其中必然含有一些杂质.如果对锅炉给水不进行处理,锅炉运行不久就结有很厚的水垢,水垢的导热系数仅为金属的1/20～1/50.锅炉结垢后将使排烟温度增高、锅炉供暖效率降低,耗煤量增加.锅炉给水除氧系统存在溶解氧超标问题,原因是进除氧器的水温不能满足除氧的温度要求,除氧器的塔内损坏.通过脱盐水复热改造以提高除样器进水温度、采用加固除氧器塔内喷嘴的方法完善除氧设备性能和改造取样器减小分析误差、规范操作以稳定除氧器压力和水位,将锅炉给水溶解氧稳定在5μg/L左右,消除了锅炉长周期稳定运行的隐患.

After combining with years of work experience, and referring to the large number of documents ,I explained the general industrial water boiler water quality that poor water quality of the boiler on the harm were caused by industrial boilers and proposed protection measures. Water boiling feed basically uses the city tap water. Because water is not absolutely pure, and is bound to contain some impurities. If you do not deal with the boiler feed water, boiler operation will soon end with a very thick scale, which is only 1 / 20 ~ 1 / 50 of the thermal conductivity of metal . After scaling the boiler flue gas temperature will increase, reducing the efficiency of the boiler heating, coal consumption increased. Boiler feed water dissolved oxygen oxygen system has exceeded the problem because the water temperature into the deaerator temperature can not meet the oxygen requirements of deaerator tower damage. Transformation through the desalination of water re-heat water is in order to improve inter injector temperature, the use of reinforcement methods deaerator tower nozzle device performance improvement and transformation of oxygen sampler reduce the analytical error. Standarded operations to stabilize the deaerator pressure and water level, the boiler feed water dissolved oxygen stable at 5μg / L or so, eliminating the long-term stable operation of the boiler hidden.
