Abstract

Characteristics of GTL (gas to liquid) kerosene laminar diffusion flame were investigated experimentally. To clarify the flame characteristics of the GTL kerosene, conventional kerosene, aromatics addition GTL kerosene, naphthene addition GTL kerosene and n-paraffin kerosene were also used. Each fuel was burnt using a wick combustion burner. Flame length, fuel consumption rate and flame temperature of each flame were measured. In the case of GTL kerosene, soot release to surroundings was not observed. Thus, flame length of the GTL kerosene flame was shorter than other flames. Compared to conventional kerosene, the GTL kerosene indicated smaller fuel consumption rate and higher flame temperature. Obtained results suggested that the flame characteristics were greatly influenced by soot formation characteristics within the flame. To investigate the concentration distributions of polycyclic aromatic hydrocarbons (PAH) regarded as the soot precursor and soot particles, laser-induced fluorescence from PAH and Mie scattering from soot particles were measured. Distribution of PAH fluorescence was significantly differed from GTL kerosene and conventional kerosene, and PAH fluorescence and Mie scattering intensities of GTL kerosene were much lower than conventional kerosene.
