煤基喷气燃料在地面单管燃烧室内燃烧和排放特性研究

为研究煤基喷气燃料的燃烧和排放特性，通过改造的单管燃烧室评估了煤基喷气燃料和石油基RP-3喷气燃料的燃烧和排放特性差异.试验结果表明:煤基喷气燃料具有更加优异的贫油点火和贫油熄火性能，两种喷气燃料的燃烧和排放特性随燃油流量和燃烧室出口温度的改变呈现出一致的变化趋势，在相同质量流量下，煤基喷气燃料的燃烧和排放性能要低于RP-3，在相同燃烧室出口温度时，煤基喷气燃料燃烧时的壁温要低于RP-3. 

Studies on combustion and emission characteristics of coal-based jet fuel in ground individual can combustor

By the improved individual can combustor, the differences of the combustion and emission characteristics between coal-based jet fuel and petroleum-based RP-3 jet fuel were evaluated. The results showed that the coal-based jet fuel had better lean ignition and lean blowout performances; in addition, the combustion and emission characteristics of these two jet fuels exhibited the same trends when the fuel flow or exit temperature changed. However, the combustion and emission characteristics of the coal-based jet fuel were slightly lower than those of the RP-3 at the same fuel flow, furthermore, at the same exit temperature, the wall temperature of the coal-based jet fuel was lower than that of the RP-3.
