Failure Analyses of Air Preheating Tube of a Heating Furnace and Its Improvement Measures
摘 要
通过金相检验、X射线衍射分析以及X射线光电子能谱(XPS)分析,得出加热炉空气预热器管破坏原因是硫酸露点腐蚀和高温燃气腐蚀的共同作用所致,并对此提出相应预防措施.
Abstract
The failure reesons of an air preheating tube were investigatal by using microstructure examination,X-ray diffraction and XPS tests.The results showed that the failure causes of the tube were the co-action of the suffuric acid dew point corrosion and high tempreture fired gas corrosion.Some improvement measures put forward.
