热水锅炉是近几年新兴的采暖热源,用热水采暖房间温度适宜舒适,而且比蒸汽采暖有明显的节煤效果,故深受采暖用户的欢迎。但是通过几年来停炉,内外检验却出乎意料之外的发现有些热水锅炉腐蚀情况非常严重,值得引以借鉴。本市某部干休所的120万千卡热水锅炉(KZG2—8改为热水运行)仅运行一冬,烟管点状腐蚀深度达2mm 以上,用尖锤轻轻一击即透,被迫全部更换烟管。类似这样的锅炉产生点状穿孔性腐蚀,程度虽有不同,但后果都是穿孔漏水,不是大修就是报废。其数量相当可观,急得这些单位直发楞。
Hot water boiler is a new heating source in recent years, with hot water heating room temperature suitable for comfort, but also significantly than the steam coal saving effect, it is well received by the heating users. However, after several years of shutdown, both inside and outside the test unexpectedly found that some hot water boiler corrosion is very serious, it is worth learning from. The city of a dry retired 1.2 million kilocalories of hot water boiler (KZG2-8 to run hot water) only run a winter, tobacco pipe pitting corrosion depth of 2mm or more, with a sharp hammer that is, Forced to replace all the tobacco pipe. Similar to the boiler produces punctate punctate corrosion, although the degree of difference, but the consequences are perforated leakage, not overhaul is scrapped. Its number is considerable, anxious these units straight hair Leng.
