摘　　要：为提供热光伏系统均匀的高温辐射源,利用SiC多孔介质作为燃烧媒介,组织丙烷燃烧,并结合回热、预热等手段以提高燃烧温度。结果发现,燃烧功率为4.3 kW时,多孔介质表面温度最高可达1000℃以上。低当量比燃烧可使表面温度梯度更低,当量比0.5时为1.07℃/mm。回热显著提高了多孔介质表面温度。Propane burned in SiC porous media to obtain radiant source with high temperature and low temperature gradient for TPV system. Assisted with thermal recycle and pre-heating, burning temperature increased. Experimental investigation found the surface temperature of SiC porous media reached over 1000℃ at firing rate 4.3 kW. Combustion at lower equivalence ratio obtained a smaller temperature gradient, the ratio 0.5 corresponding the gradient 1.07℃/mm for instance. The results indicated heat recycle efficiently increased the surface temperature of SiC porous media.
