摘要
锅炉爆管是常见的也是比较严重的事故之一。以某糖厂锅炉省煤器管断裂,水冷壁管爆管为例,对锅炉进行了内部检验,从爆管外观、壁厚检测、硬度检测及金相检验等多方面对爆管的原因进行了分析,提出了爆管后的处理及预防措施,为今后防范同类的事故及锅炉检验提供一定的帮助。
Boiler tube burst is one of the most common and serious accidents,boiler water wall tube explosion and fracture of economizer tube in a sugar factory,internal inspection of boilers was carried out.The causes of tube explosion are analyzed from the aspects of appearance,wall thickness test,hardness test,metallographic examination and so on.The treatment and preventive measures after tube explosion are put forward,provided some help for preventing similar accidents and boiler inspection in the future.
