锅炉在运行时,如果水处理工作做得不好,其受热面就会结成水垢,水垢是导致热性极差的特质,它不仅会阻碍热量的传递,浪费大量燃料,而且还会危及锅炉的安全运行.因此,经常清除锅炉内的水垢是一项重要工作.目前,清除水垢采用比较多的方法是盐酸清洗,因为盐酸能与水垢发生化学反应,使其脱落,并可变为松软的泥垢排出锅炉外.众所周知,盐酸是具有极强的腐蚀性的化学物品,当盐酸抽吸到锅炉简体内后,如果添加的缓蚀剂效果不好,盐酸便会与锅炉钢材发生反应而产生氢气(Fe+2HCL→FeCL_2+H~2↑).氢气是易燃易爆气体,只要遇到丁点火星就会燃烧爆炸,造成严重后果.
When the boiler is in operation, if the water works poorly, its heating surface will form scale, scale is the cause of poor thermal characteristics, it will not only impede the transfer of heat, waste a lot of fuel, but also endanger the boiler Therefore, the regular removal of scale in the boiler is an important task.Currently, the most widely used method of removing scale is hydrochloric acid cleaning, because hydrochloric acid can chemically react with the scale to make it fall off and become soft It is well known that hydrochloric acid is a highly corrosive chemical. Hydrochloric acid generates hydrogen when reacted with boiler steel when hydrochloric acid is pumped into the boiler. If the corrosion inhibitor added is not effective, (Fe + 2HCL → FeCl_2 + H ~ 2 ↑) Hydrogen is a flammable and explosive gas, which will burn and explode as long as it encounters a small amount of dust, causing serious consequences.
