本文通过对近百台超(超)临界机组锅炉高温过热器的缺陷情况统计分析,得到了过热器缺陷的发生概率,并按照缺陷发生概率的高低以及发生部位进行分类,为进行高温过热器检验提供了参考。1高温过热器系统主要缺陷超(超)临界电站锅炉高温过热器一般布置在烟气温度较高区域,易出现的缺陷和位置与亚临界锅炉区别较大。本文对超(超)临界锅炉高温过热器缺陷
Through the statistical analysis of the defects of the superheater of nearly 100 ultra-supercritical units (boilers), the probability of superheater defects was obtained and classified according to the probability of occurrence of defects and the location of occurrence. In order to carry out the test of high temperature superheater Provided a reference. 1 high temperature superheater system main defect Super (super) critical power plant boiler high temperature superheater is generally arranged in the flue gas temperature is higher, prone to defects and location and subcritical boiler difference. This article super (super) critical boiler high temperature superheater defects
