摘　　要：本文基于民用燃气具的工作特点,重点分析了民用多孔介质燃烧器的研发过程中遇到的主要挑战。研究发现,减少向上游气体的热量辐射、改善气流分布均匀性可有效阻止回火;多孔介质通过分块及分层布置,能够提高其抗热震性并延长燃烧器的使用寿命;水冷盘管则可确保燃烧器壳体的低温状态。该研究结果对于民用多孔介质燃烧器的开发具有一定指导意义。Based on the working characteristics of civil gas appliances,this paper focuses on the main challenges encountered in the development of civil porous media burners.It is found that flashback can be effectively prevented by reducing the heat radiation of upstream gas and improving the uniformity of gas flow distribution.Porous media can improve its thermal shock resistance and prolong the service life of the burner through block and layer arrangement.The water-cooled coil can ensure the low temperature state of the burner shell.The research results have certain guiding significance for the development of civil porous media burner.
