Abstract
The continuously increasing global energy demand has driven many countries to seek alternatives to fossil fuels. One potential solution is the use of renewable fuels such as biodiesel and its blends with additives. This study investigates the effect of air velocity and fuel composition (B40, B100, B40 + 20% n-butanol, B100 + 20% n-butanol) on flame characteristics, combustion performance, and exhaust emissions in a JINIL-JL26D burner. Increasing air velocity significantly reduces flame length, width, and light intensity due to enhanced mixing and convective cooling. Flame temperature distribution exhibits a peak profile at medium air velocities. Thermal efficiency increases up to an optimum point, and total energy output rises consistently with air velocity. Emissions of carbon monoxide (CO), unburned hydrocarbons (HC), and smoke opacity decrease sharply with increasing air velocity. Butanol-blended fuels produce lower pollutant emissions and exhibit more efficient O₂ consumption due to their intrinsic oxygen content, although with slightly lower peak flame temperatures and thermal efficiency. The results of this study provide valuable insights for optimizing burner design and formulating cleaner alternative fuels.
