本文对 HG—670/140—9型锅炉高温对流过热器的超温问题进行了全面的研究与分析,用三维数值计算方法计算了过热器入口的速度分布和温度分布,找到了高温对流过热器超温的原因并提出了改进措施,有关结论对同类型锅炉过热器的改进有指导意义。
In this paper, the over-temperature problem of the HG-670 / 140-9 boiler convection superheater was thoroughly studied and analyzed. The velocity distribution and temperature distribution of the superheater inlet were calculated by the three-dimensional numerical calculation method. The high temperature convection superheater The reason of over-temperature and put forward the improvement measures, the relevant conclusions have instructive significance for the improvement of the same type boiler superheater.
