摘　　要：采用催化材料铂加工的微平板燃烧室,与碳化硅材料加工的微平板燃烧室在相同条件下进行了试验对比,分析了不同流量、不同当量比和不同燃烧室尺寸条件下催化燃烧对微燃烧性能的影响。试验结果表明,同样流量下,采用催化燃烧时的外壁面测点温度均比采用无催化的碳化硅燃烧室的高,且温度分布更均匀;不同于无催化的碳化硅燃烧室,铂加工的燃烧室在当量比为1时内部燃烧已经比较充分;催化燃烧能提高微尺度燃烧的稳定性,扩展燃烧极限。Experimental investigation of catalytic combustion is presented in a platinum micro combustor, compared to the micro combustor of silicon carbide under the same testing couditions. The effects of three major parameters on combustion was studied, namely flow rate, hydrogen to oxygen mixing ratio and the size of the combustor. The results show that the temperatures along the wall of the platinum micro combustor is much higher than that of the non-catalytic SiC micro combustor, the temperature distribution more uniform. When hydrogen to oxygen mixing ratio is stoichiometric ratio, the internal combustion is relatively full in the platinum micro combustor. Catalytic combustion can improve the stability of micro-scale combustion and expansion the combustion limits.
