Characteristics of Combustion and Emissions of Biodiesels in a Controllable Active Thermo-atmosphere
The combustion and emission characteristics of diesel and two biodiesels were studied in a vitiated coflow burner by means of the high-speed video camera system and transient gases analyzer. The results show that ignition delays (ID) of biodiesels are obviously different from the conventional diesel, which is due to both physical delay and chemical delay by different physical-chemical properties. And the attribution to the physical delay from the poor evaporation and atomization is significant. ID of biodiesels significantly decreases with increasing the coflow temperature. The results of emission concentration in flame show that total hydrocarbon (THC) emissions of biodiesels are significantly lower than that of conventional diesel, and THc distribution is similar for two biodiesels. And the NO emission of biodiesels flame in burner is slightly lower than that of diesel, which is due to the different temperature distribution in flames based on the flame structure.
