摘　　要：强化微燃烧器内部燃烧过程,对提高微型热光电系统能量输出和实现较低排放有重要的意义,为实现这一目的,本文进行了不同结构尺寸的微燃烧器的燃烧试验。研究结果表明:改变微燃烧器形状,能够改善燃烧器内部燃烧反应过程,从而提高微型燃烧器的外壁面温度和辐射强度,并且能够降低排放;在试验的燃烧器结构中,平板1型具有较高壁面平均温度和较低的CO、HC排放。Strengthening the inner combustion process of micro-burner plays a great importance role in enhancing the output efficiency and lowering emission of the micro-thermophotovoltaic (MTPV) system. In order to achieve this purpose,combustion experiments were investigated with different structural micro-burners in this paper. The experimental results show that with the changes of structure and size,the inner combustion process of the micro-burner can be improved,which consequently enhances the outer wall temperature and radiation intensity,and reduces emission components of the micro-combustor. Among the experimental microburners,flat type 1 has the higher average wall temperature and lower CO and HC emissions.
