我国现行的GB 1576—2001《工业锅炉水质》标准中,把额定工作压力小于或等于1.0MPa的蒸汽锅炉在采用锅外化学处理时的锅水碱度指标上限值作出“适度放宽”的调整.解决了长期以来大量在用小型锅炉用水普遍采用钠离子交换处理后。在正常排污情况下,锅水碱度超出标准上限值以及要保持锅
China’s current GB 1576-2001 “industrial boiler water quality” standard, the rated working pressure is less than or equal to 1.0MPa steam boiler pot chemical treatment of the pot when the upper limit of alkalinity indicators made “moderate relaxation” To solve a large number of long-term use of small boiler water commonly used after sodium ion exchange treatment. Under normal sewage conditions, pot alkalinity exceeds the standard upper limit and pots are to be maintained
