Analysis and treatment for inner surface iron oxide in boiler connecting pipes

HE Xi1,MA Xiao2,JIN Jie-ping1,XU Xian-fu1(1.Electric power engineering Lim.Co.of China power investment corporation,Shanghai 200233,China;2.China power investment corporation,Beijing 1 00032,China)  
The iron oxide exists at the inner surface of heating surfance connecting pipes in Kaifeng power plant 2×600 MW units.The iron oxide microstruture is anlyzed in this paper,the PBR and expansion coefficient of FeO,Fe3O4 and Fe2O3 are compared,and the reason of the iron oxide is obtained.It is verified that H2SO4 pickling is an effective method to clean iron oxide.
