2002年7月,广东中山市一家泡沫厂,1台DZL2-1.0-AⅡ三回程燃煤链条炉排锅炉,投运2个半月,就发现烟管多处漏水,主要部位在正对人孔处的烟管,其周围区域的烟管,也出现麻坑。由于锅炉运行不久,还在制造和安装质量“三包”期内,该厂邀请制造厂和安装单位对该台锅炉问题进行分析:认为是锅炉煮炉加药不当造成的,即加药时没有先用热水对药品进行溶解,而是直接从人孔倒人固体药品颗粒,未溶解的药品粘在烟管上,造成碱腐蚀所致,由安装单位对漏水和有麻坑的烟管作了更换处理。锅炉继续投入使用,2个月后,相同部位的烟管,又出现了同样的漏水问题。1原因分析为了查明原因,彻底解决锅炉存在的问题,以
July 2002, Zhongshan City, Guangdong, a foam factory, a DZL2-1.0-A Ⅱ three-way coal-fired chain grate boilers, put into operation two and a half months, found that multiple pipe leakage, the main part of the hole in the manhole The smoke pipe, the smoke pipe around the area, also appeared Ma Hang. Due to the boiler running shortly before the manufacture and installation of quality “Three Guarantees” period, the factory invited the manufacturer and the installation unit to analyze the boiler problem: that is caused by improper boiler boiling furnace, dosing When there is no first hot water to dissolve drugs, but directly from the manhole upside down solid drug particles, undissolved drugs stick to the tobacco pipe, resulting in alkali corrosion caused by the installation unit on the leakage and Ma Hang smoke The tube was replaced. Boiler continue to put into use, two months later, the same part of the pipe, there have been the same problem of leakage. 1 reason analysis In order to find out the reason, solve the problem of the boiler completely
