低压锅炉水质标准中规 定: 给水的硬度当采用炉内处 理时小于或等于3.5毫克当量/ 升,采用炉外处理时小于或等 于 0.04毫克当量/升。炉水的 碱度为8—20毫克当量/升,pH 值为10—12。上述标准给低压 锅炉水处理工作提出了两个任 务:一是在给水未进入锅炉之 前尽最大可能降低水中 Low pressure boiler water quality standards: water hardness of less than or equal to 3.5 milliequivalents / liter when using furnace treatment, less than or equal to 0.04 milliequivalents / liter when treated outside the furnace. The alkalinity of the boiler water is 8-20 meq / l and the pH is 10-12. The above standards give two tasks to the low-pressure boiler water treatment work: First, to minimize the water supply before it enters the boiler
