【摘要】 针对锅炉燃气燃烧器中易出现的回火问题，根据燃烧学的基本原理，采用有限元软件分析方法，分析了回火原因，提出了解决方案，并将其应用于实际的燃烧器产品的结构设计中．通过试运行，本方案切实可行．更多还原

【Abstract】 To solve the backfire problems which we often meet in the process of boiler gas burner design, we found out some backfire resolving methods based on the structural reasons. In this process, we adopted the conbustion theories, the finite-element analysis method and succeded in practice.更多还原
