| 摘 要： | 为了研究碳氢燃料燃烧产物NOx的排放,构建了射流搅拌燃烧反应器(JSCR)试验系统,并经过了初步验证.随后利用该试验系统对航空煤油RP-3的燃烧NOx排放进行了测试,射流搅拌燃烧反应器内压力为2×105 Pa和3×105 Pa,进口温度为650K,当量比范围为0.5~1.2.研究结果表明:在当量比为0.5~1.2范围内,航空煤油燃烧NOx排放先随当量比的增大而增多,在当量比为0.95附近达到最大值,随后减少;NOx排放随压力的增大而增多.同时,验证了该射流搅拌燃烧反应器可作为研究碳氢燃料燃烧产物的基础试验平台.

| Abstract: | In order to study the combustion product NOx emissions of hydrocarbon fuel, a jet stirred combustion reactor (JSCR) experimental system was built and validated preliminarily. Then, kerosene RP-3 combustion NOx emission was tested using the experimental system under the conditions of pressures in jet stirred combustion reactor of 2×105Pa and 3×105Pa, inlet temperature of 650K, and equivalence ratios of 0.5 to 1.2. The study results show that when equivalence ratio of 0.5 to 1.2, the amount of kerosene combustion NOx emission firstly increases with the growing equivalence ratio and reaches the maximum value in the vicinity of the equivalent ratio of 0.95, and decreases subsequently; the amount of kerosene combustion NOx emission increases with the pressure rise. The jet stirred combustion reactor can be used as a verification test rig for combustion products of hydrocarbon fuels. |
