近年来,热水锅炉氧腐蚀日趋严重。由此造成的事故时有发生。热水锅炉一般都没有除氧措施.热水锅炉的腐蚀主要由溶解氧含量引起的。我市供热公司的2台直接供热式承压热水锅炉一在江南地区,一在江北地区,仅就氧腐蚀成因、现象及除氧措施简要总结一下。1江南锅炉水质情况1.1江南锅炉基本情况锅炉型号为DZL14-0.7/115/70—AⅡ,使用深井水,水质清澈透明,有锅外软化水处理,给水不除氧。水在经过处理系统过程中,与空气接触,致使锅 In recent years, hot water boiler oxygen corrosion is worsening. The resulting accidents have occurred. Hot water boilers generally do not have oxygen removal measures. Hot water boiler corrosion mainly caused by the dissolved oxygen content. City heating company 2 sets of direct heat-type pressure-fed hot water boiler in the southern region, one in the Jiangbei region, only on the cause of oxygen corrosion, the phenomenon and the brief oxygen measures summary. 1 Jiangnan boiler water quality 1.1 The basic situation of the southern boiler Boiler model DZL14-0.7 / 115/70-A Ⅱ, the use of deep well water, water quality is clear and transparent, there is softened water treatment outside the pot, the water is not oxygen. Water in the process of dealing with the system, with the air contact, resulting in pot
