| 摘 要： | 当超临界直流锅炉燃用煤的硫含量St.ar平均值在1.5%以上时，一般会出现高温腐蚀。通过对某超临界前、后墙对冲燃烧直流锅炉所送检的水冷壁管烟气侧腐蚀状况，采用目视、体视镜、电镜、能谱以及X射线衍射分析等方法进行检查分析，确定了高温硫腐蚀的产物，并对成因进行分析，然后提出防治的措施和建议，为预防高温硫腐蚀提供参考。 |

| Abstract: | When the content of sulfur St.ar is more than 1.5% in the coal,high temperature sulfur corrosion will generally occur in supercritical concurrent boilers.An analysis is made of the corroded water wall samples of a supercritical concurrent boiler by such means as visual inspection,stereoscope,electron microscope,energy spectrum and X ray diffraction,and the production of high temperature sulfur corrosion is determined.Based on the analysis of the causes for the corrosion,some prevention measures are proposed,which can be used as a reference for prevention of high temperature sulfur corrosion. |
| Keywords: | supercritical concurrent boiler water wall tube high temperature sulfur corrosion energy spectrum analysis X ray diffraction analysis |
