| 摘 要： | 由于外取热器壳程的烟气温度很高，使得翅片管温度梯度大，产生很大的热应力。通过调整翅片管不同的结构型式及取热强度，采用有限元方法对翅片管在温度及内压两种载荷工况作用下的15个结构模型进行了计算和分析，指出了设计时需要考虑的要点，从而为工程设计的结构优化提供技术参考。

| Abstract: | As the flue gas temperature in the shell side of catalyst cooler is high, the temperature gradients of finned tubes are great and the resulting thermal stress is big. Through changing the constructions of finned tubes and heat removal intensity, 15 construction models under the temperature and internal pressure loads are calculated and analyzed by finite element. The necessary considerations in the engineering design are proposed, which provide a good technical reference for the optimization of finned tube construction in catalyst cooler design. |
