In this study, effect of fuel properties on diffusion combustion of kerosene was investigated experimentally. Five types of kerosene, which distillation and composition properties were different, were used as the test fuel. Laminar diffusion flames of kerosene were formed by using wick combustion burner. Fuel consumption rate, flame temperature and flame luminosity of each flame were measured. As the results, fuel consumption rate proportionally increased with decreasing volume average boiling point, and both temperature and luminosity decreased as the aromatic content in the fuel increase. To investigate the effect on soot formation of fuel properties, concentration distributions of polycyclic aromatic hydrocarbons (PAHs) and soot were measured by laser-induced fluorescence (LIF) and laser-induced incandescence (LII). Both PAHs-LIF intensity on wick and LII intensity of soot emission increased with the content of aromatic compounds in the fuel became higher.
