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。
Experiments and experiments were carried out under the same conditions with the micro-plate combustion chamber fabricated by the catalytic material platinum processing and the micro-plate combustion chamber processed by the silicon carbide material. The effects of the catalytic combustion on the micro-combustion at different flow rates, different equivalent ratios and different combustion chamber sizes were analyzed. The impact of performance. The experimental results show that, at the same flow rate, the temperature at the outer wall surface of the catalytic combustion is higher than that of the non-catalytic silicon carbide combustion chamber, and the temperature distribution is more uniform. Unlike the non-catalytic silicon carbide combustion chamber, Combustion chamber in the equivalence ratio of 1 internal combustion has been more adequate; catalytic combustion can improve the stability of micro-scale combustion, combustion limit expansion.
