摘要
针对H型鳍片管应用于高烟温区的情况,采用有限元数值求解鳍片的温度工况,比较各种结构方案的计算结果,作出具体工程中的合理结构选择;所采用的方法和所含有的信息对于工程实践具有参考价值。
H-Type Finned Tube has been getting more application either for new built plant or retrofit in particular for low NOx. Temperature of fin metal should be considered as impor- tant design factor either for heat transfer or for safety of equipment. PDETOOL in Matlab is used for calculation of temperature field of H-type finned tube economizer for various cases of new built 410 t/h high pressure boiler and for checking a existing 1 050 MW ultra supercriti- cal boiler. A optimizing design for the new one is conducted. The method of analysis and a lot of relevant information could be referred for design engineers.
