摘　　要：为了对高温气冷堆甲烷蒸汽重整制氢系统中氦气加热的蒸汽重整器的性能进行定量化的分析,基于一维拟均相模型建立了一个动态的数学模型,开发了相应的计算程序。利用日本原子能研究院的实验结果进行了稳态下的模型验证与计算分析。研究表明:稳态的计算与实验结果吻合较好;化学反应速度不是影响性能的主要因素;相对光滑管,中心管采用肋片管使蒸汽重整器性能有明显的提高。In order to quantitatively analyze the performance of the helium-heated reformer used in steam methane reforming hydrogen production system connected with high temperature gas cooled reactor, a dynamic model has been set up based on one-dimension quasi-homogeneous phase model. And a computer program is developed. Model verification is performed under steady state using test results of Japan Atomic Energy Institute. The steady state calculation results fit well with the experiment results. Reaction velocity is not the main factor influencing the performance. Reformer tube with finned central tube improves the performance remarkably comparing with smooth central tube.
