蓄熱式可重組燃燒系統－以蓄熱式隧道窯為例
Reconfigurable Regenerative Combustion System-Take Regenerative Tunnel Kiln as an Example
摘要
本研究利用規格化燃燒器、蓄熱艙、控制系統、國際標準安全閥站組合以及最適化爐型等思惟設計可重組燃燒系統，不同於過去蓄熱式工業爐製程設備設計及開發流程，模組化快速設計可依據廠商製程需求，結合新技術導入與規格化組合，建立快速評估分析技術，縮短50%開發週期。並透過模擬分析探討平焰蓄熱燃燒器的火焰型態、流場以及漩流數（swirl number）、隧道窯爐內燃燒器不同的蓄熱切換方式及切換時間對爐內熱流場以及工件升溫情形的影響。由結果可知，平焰蓄熱燃燒器的漩流數在經過燃燒器內部的流道後，漩流數有明顯的上升，後續流場在經過整流流道後，漩流數有小幅下降，又再經由喇叭噴口噴出後，漩流數可達高強度漩流（漩流數＞0.6），符合隧道窯燒成爐的需求，可提供隧道窯設計參考。

This study uses the standardized burner, regenerative chamber, control system, combination of international standard safety valve station and optimized furnace type to design a reconfigurable sub-system according to different fields of use, which is different from the past regenerative industrial furnace process equipment design and Development process, modular rapid design can be based on the manufacturer's process requirements, combined with new technology introduction and standardized combination, to establish rapid evaluation and analysis technology, shortening the development cycle by 50%. And through simulation analysis, the flame type, flow field and swirl number of the flat flame regenerative burner are discussed, as well as the different regenerative switching methods and switching time of the burner in the tunnel kiln on the heat flow field in the furnace and the heating of the workpiece. Impact. It can be seen from the results that the swirl number of the flat flame regenerative burner increases significantly after passing through the swirl channel inside the burner. After the horn nozzle is ejected, the number of swirls can reach high-intensity swirls (the number of swirls ＞ 0.6), which meets the requirements of the tunnel kiln firing furnace. The results in this thesis can be provided to the tunnel kiln design.
