电站锅炉监督检验过程中光谱分析应用及常见问题

Application and Common Problems of Spectral Analysis in Supervision and Inspection of Utility Boilers

电站锅炉作为大型复杂的承压特种设备,其在制造和安装时使用的材料种类多,易混用错用。本文通过总结电站锅炉在监督检验涉及标准中对光谱分析的规定,体现材料复验的重要性;通过对标准试样进行光谱分析验证便携式X射线荧光光谱分析仪可以满足现场光谱分析的要求;总结监督检验过程中现场光谱分析发现的问题并提出相应的检测注意事项和措施。

As large and complex special pressure equipment,power boiler uses a variety of materials in its manufacture and installation,which are easy to mix and misuse.The importance of material inspection is reflected by summarizing the provisions of spectral analysis in the supervisory inspection standards of power boilers.Through the spectral analysis of standard samples,we can know that the portable X-ray fluorescence spectrometer can meet the requirements of on-site spectral analysis.This paper summarizes the problems found in on-site spectral analysis in the process of supervisory inspection,and puts forward corresponding detection precautions and measures.
