    停炉后的数控采暖锅炉,锅内潮湿积水,炉体外部有烟灰炉渣的侵蚀和锈蚀,如保养不好,停炉期间的腐蚀往往比运行时更为严重。那么数控采暖锅炉停炉后如何维护保养?
    After the shutdown of the NC heating boiler, the pot wet water, outside the furnace body with ash slag erosion and corrosion, such as poor maintenance, corrosion during shutdown often than runtime is more serious. So, how to maintain the CNC heating boiler after shutdown?
    在数控采暖锅炉长期停用时,应十分注意炉体外部的防腐保养问题。首先在数控采暖锅炉停炉冷却后,必须彻底清除受热面的积灰和炉排上部、炉体下部的灰渣。然后要保持烟道有一定的自然通风。一般情况下,为了防潮应在炉膛、烟道中放置干燥剂。如以生石灰作为干燥剂,则每立方米炉膛或烟道内一般应放置3kg左右。放置后应严密关闭所有的通风门。生石灰变粉后要更换。如数控采暖锅炉房位置低洼,停炉期间地面泛潮严重时,则应采用经常小火烘烤和放置干燥剂相结合的办法。如果数控采暖锅炉停炉时间很长,在彻底清除烟灰后在炉体金属外表面涂以红丹油或其它防腐漆?
    In the numerical control heating boiler for a long time, should pay attention to the outside of the furnace body maintenance problem. After the first in NC heating boiler shutdown cooling must be thoroughly remove deposit on the heating surface slag ash and the upper grate, the lower part of the stove body. And then to keep the flue has a certain natural ventilation. Under normal circumstances, in order to damp should be in the furnace, flue placed desiccant. If the lime is used as desiccant, the furnace or flue of each cubic meter should be placed about 3kg. Close all ventilation doors after placement. After the change of lime powder to be replaced. If the position of the NC heating boiler room is low, when the ground water flooding is serious, it should be combined with the regular small fire baking and placing desiccant. If the NC heating boiler shutdown time is very long, in the complete removal of the ash outside the furnace body metal surface coated with Hongdan oil or other anticorrosion paint?
    至于炉体内部停炉的防腐保养方法,则要按停炉时间的长短来定。一般情况下,停炉不超过一个月的可用湿法保养,一个月以上的应采取干法保养?
    As for the maintenance of the furnace body inside the maintenance method, it should be according to the length of time to stop the furnace to set. Under normal circumstances, the furnace is not more than one month of available wet maintenance, more than one month should be taken dry maintenance?
    干法保养时要注意以下几点问题:干燥剂不要直接接触数控采暖锅炉金属表面,可装在铁盘等容器内;放置干燥剂后,要关严手孔和其它孔盖,汽、水管道上的阀门必须截断;生石灰变粉应及时更换?
    Dry maintenance should pay attention to the following several points: desiccant don't directly contact NC heating boiler metal surface, installed in the iron plate and other containers; placed desiccant, to close the strict hand holes and other cover, steam, water pipe valves must be truncated; lime variable powder should be replaced in a timely manner?
    而采用湿法保养时,要注意炉水最好用凝结水,其次可用原有的炉水,再次是软化水;加碱后,炉水用微火加热至80?100℃压力升至2?3表压后保护2?3小时,使其循环达到炉水碱度均衡,压力降低时,再把炉水加满,造成1.5?4表压,并在整个保养期间一直保持这个压力,碱度应定期化验,降低时,应随时补充;冬天,湿法保养要注意防冻,特别是排污通道和省煤器部分;数控采暖锅炉重新使用前应全部放出锅内碱水,最好备储液池,以利再用。同时须用净水冲洗。
    Alkaline before re-use decreased and, once again, it is best to use the wet maintenance, should pay attention to the boiler water condensation water, secondly available original boiler water softening water, alkali and boiler water with Weihuo heated to 80? 100 DEG C and a pressure rose to 2? 3 gauge protection 2 ~ 3 hours, the cycle to achieve the boiler water alkali balance degree, the pressure reduced, the boiler water to fill, 5? 4 gauge, and in the maintenance period has been to maintain the pressure and alkalinity should be testing on a regular basis, should be added at any time; in winter, wet maintenance should pay attention to antifreeze, especially the sewage channel and the provincial coal machine; NC heating boiler should release all of the pot, it is best to prepare liquid storage tank, in order to facilitate reuse.
