Abstract: Applying bio-oil generated through thermochemical conversion in power plants is a crucial problem in current energy studies. In this study, varying proportions of cedar sawdust bio-oil produced through fast pyrolysis were mixed in the kerosene samples to analyze their spray combustion characteristics with various oxidizer velocities. These results indicated that the spray angle increased with increased oxidizer velocity, reducing the droplet distribution. Moreover, the turbulence effect enhanced the effect of mixing the vaporized droplets and the oxidizer, thereby hastening and intensifying the combustion and shortening the flame length and lift off. The bio-oil produced through fast pyrolysis contained various types of volatile substances. Therefore, increasing the bio-oil proportion in kerosene reduced the spray combustion regime. Additionally, when the volume percentage of bio-oil in kerosene reached 15%, the low heating value of the bio-oil lowered the flame temperature in combustion. Furthermore, the emission of various substances during combustion was closely correlated with the oxidizer velocity and bio-oil proportion.
