我市某厂一台 KZG 2—8的快装锅炉,83年底正式投入运行,由于锅炉安装时锅筒的前后倾斜尺度控制不当,前部锅筒几乎低於后部锅筒,使锅炉在停炉时排水不干净,出现了前部底部、中间后拱管头周围少量积水现象。84、85二年锅炉年检,发现有轻微的氧化腐蚀点,面积范围约200×150mm~2。对这些腐蚀小点没有引起足够的重视,虽然发现了问题,但没有对存在的问题采取有效的防患措施,比如在检修时纠正锅炉锅筒的倾斜尺度,防止停炉时造成锅筒底部积水潮湿;机修期间没有彻底清除腐蚀小点的锈蚀物并采取防腐措施,运
A factory in our city a KZG 2-8 fast boilers, put into operation at the end of 83, due to improper control of the front and rear tilting of the boiler when the boiler is installed, the front drum is almost lower than the rear drum, the boiler at the stop When the furnace drainage is not clean, there is a front of the bottom, after the middle of a small amount of water around the arch pipe water phenomenon. 84,85 years of boiler annual inspection, found a slight point of oxidation corrosion, an area of about 200 × 150mm ~ 2. These corroded dots did not pay enough attention to, although found the problem, but did not take effective measures to prevent existing problems, such as the maintenance of the tilt angle of the boiler drum to prevent boiler shutdown at the end of the area Water damp; did not completely remove corrosive dots during corrosion and take corrosion protection measures, transport
