摘　　要：平板式微热光电(MTPV)能源系统采取全新的亚毫米平板式燃烧室取代以往的圆柱式,对应的面容比的增加将提高燃烧室壁面的能量输出,从而提高系统的能量密度.针对石英玻璃材质的平板式燃烧室,改变氢气流量、氢氧混合比以及平行板间夹缝距离等,进行燃烧试验,测试了外壁面和出口的温度,进而分析几种因素的影响规律.结果表明,在一定条件下,亚毫米平板式微燃烧室能克服壁面能量损失激增而带来的着火困难和火焰淬熄等问题,能够实现稳定燃烧.合理选择工况参数,可以提高燃烧室温度和优化温度分布,提升系统工作性能.A new type sub-millimeter plane cell combustor was designed in place of previous cylinder combustor in the micro-thermophotovoltaic （MTPV） power system, in order to obtain more radiant area under the same combustion volume and hence to enhance energy density. Combustion experiments were carried out for various factors affecting the combustion such as the distance of the parallel quartz plates, mixture mass flow rate and mixing ratio of hydrogen and oxygen. Based on measured temperatures and a- nalysis, it is believed that sub-millimeter plane cell combustor can overcome difficulties of the ignition and flameout due to increasing heat loss, and achieve stable combustion. High and uniform temperature distribution on the surfaces of the plane cell micro-combustor can be obtained by carefully selecting combustion operating parameters, so as to improve performance of the power system.
