摘　　要：随着人们生活品质提高,对民用燃气灶具节能减排的要求不断提高,对其燃烧性能提出了更高标准。利用自行搭建的实验装置系统,对新型民用多孔介质燃气灶稳定燃烧的可行性进行了实验研究。结果表明多孔介质燃气灶点火后,燃烧火焰依次经历了点火初期的表面燃烧、向上游传播、燃烧火焰界面稳定三个阶段。燃烧火焰界面稳定后,多孔介质燃气灶可实现稳定燃烧,燃气灶多孔介质上表面温度分布非常均匀,温度梯度小,燃烧CO排放浓度能够稳定在18 ppm左右,NO排放浓度能够稳定在3 ppm左右,热效率能够达到64%。实验结果验证了多孔介质燃气灶稳定燃烧的高效性,为深入研究开发多孔介质民用燃气灶具提供了研究基础。With the improvement of people's quality of life,the requirements for energy saving and emission reduction of civil gas stoves are constantly increasing,and higher standards are putting forward for their combustion performance.The feasibility of stable combustion of modern civil porous media gas stove was experimentally studied by using a self-built experimental device system.The results show that after the ignition of the porous media gas stove,the combustion flame has undergone three stages in turn:Surface combustion at the initial ignition,upstream propagation,and combustion flame interface stability.After the combustion flame interface is stable,the porous media gas stove can achieve stable combustion.The surface temperature distribution on the porous media of the gas stove is very uniform.The temperature gradient is small.The CO emission concentration can be stabilized at about 18 ppm,the NO emission concentration can be stabilized at about 3 ppm,and the thermal efficiency can reach 64%.Experimental results verify the high efficiency of stable combustion of porous media gas stove,which provides a research basis for further research and development of porous media civil gas stove.
