Talk Abstract

The characteristics of liquid fuel affect the characteristics of spray combustion or droplet combustion. These droplet characteristics include components, saturated vapor pressure, boil point, flash point, and viscosity. The magnitude of the viscosity influences the atomization characteristics, and the liquid fuel composition characteristics influence the vaporization of the fuel and the characteristics of the flash ignition and flame propagation. This study discussed the characteristics of fast and slow pyrolysis bio-oil, butanol, and Dodecane measured by GC-MS, TGA and FT-IR, and used direct images and Schlieren method synchronization technology to observe the soot formation characteristics of droplet combustion. The results indicated that the flame generated by the butanol and Dodecane fuel was mostly stable, but that in the mixed combustion of the two fuels, it was obvious that there was a bubble formed at the droplet, and there were primary and secondary micro-explosion phenomena. In the case of one bio-oil droplet, the flame surrounded the droplet during both the fast and slow pyrolysis bio-oil processes, and there were primary and secondary micro-explosions. According to the Schlieren image results, butanol and Dodecane did not leave a soot tail, which is defined as a distinct boundary in the flame image. In the droplet combustion process, the soot had a higher carbon number (alkane and aromatic hydrocarbon). Under normal gravity conditions, the soot formation position will occur during the combustion procedure changing process, and the soot tail will be formed under the buoyancy effect.

Short Biography

Dr. Shouyin Yang is a Profersssor of Department of Power Mechanical Engineering at National Formosa University, Taiwan. He focused on the laminar turbulent flame speed and mechanisms of high-pressure combustion in his Ph.D. student and post-doctoral  fellowship periods. In the passed several years, he worked on the biomass thermal-conversion and application technologies. Dr. Yang published several papers in top-ranked journals such as Powder Technology, Energy, Energy Conversion and Magment, Combustion and Flame. He was the first and corresponding author in these papers. Dr. Yang was involved in thermalchemical processing of biomass on char removal, bio-oil production, bio-oil application and heat cycling of biomass fsat-pyrolysis process. These problems is of immense interest in the utilization of biomass and coal. These researches involve both experimentation and computation.
