超超临界对冲燃烧锅炉高温腐蚀研究

Research on High-temperature Corrosion of Ultra-supercritical Opposed Firing Boiler

针对某超超临界旋流燃烧锅炉燃烧器区域两侧墙水冷壁管向火侧外壁出现的高温腐蚀现象,通过对产生高温腐蚀的原因分析,提出了预防发生高温腐蚀的措施,有效防止了该现象的再次发生。

Through the cause analysis for the high-temperature corrosion of waterwall tube fireside external surface for the walls on both sides in the area of the swirl burner for the ultra-supercritical boiler,this paper presents the preventive measures that effectively avoid that phenomenon.
