    Abstract
  • A rectangular model combustor with three counter dual-swirl Venturi-premix (CDV) injectors was designed and its combustion characteristics and performances were also investigated. The results showed that, the combustion flames were blue, which were very similar to those of lean premixed gaseous combustion. And in the above-mentioned working condition, CO and NOx emission volume fraction converted to 15 percent oxygen were less than 10×10-6 and 50×10-6 respectively. In addition, the effect of inlet air temperature change on pollutant emissions of these three CDV injectors was also investigated. It was found that the CO emission concentration was more affected by the change of inlet air temperatures than that of NOx. And the reason about above-specified phenomenon was analyzed and revealed. Moreover, the study showed that, atomizer's performances greatly influenced the characteristics of lean direct injection combustion flames. Processing technology of the fuel atomizers should be improved to ensure long-term stability of their atomization performances.
