主 题:Pyrolysis oil Atomization characteristics Spray angle Droplet velocity Droplet size distribution
摘 要:The atomization characteristics play a key role in the highly efficient combustion of pyrolysis oil derived from waste *** this study,the fuel properties of tire pyrolysis oil(TPO)were initially studied,and then a high-speed camera and a phase Doppler particle analyzer were employed to characterize the atomization feature of *** influence of pressure and nozzle orifice diameter on atomization characteristics such as spray angle,droplet velocity,and droplet size distribution was *** results showed that TPO had a high calorific value of about 43.6 MJ/kg and a low viscosity of 3.84×10^(–6)m^(2)/s at 40℃,which made it have the potential to be used as an alternative *** pressure expanded the spray angle and extended the spray in both the axial and radial *** increasing pressure,spray angle and droplet velocity raised,and the increase in crushing effect of air reduced the Sauter mean diameter(SMD)of the *** obtain proper atomization quality for combustion,the pressure is expected to be higher than 1.25 *** increasing nozzle orifice diameter,droplet velocity increased,and the SMD of the droplets increased as well due to weakened crushing effect of the ***,the pressure must be increased to maintain the atomization quality when using a nozzle with a larger *** to the lower viscosity,the velocity and particle size distribution of TPO droplets after atomization were smaller than those of diesel *** extremely small carbon black contained in TPO also contributed to the breaking of droplets and played a certain role in the size reduction of the oil droplets,but it may cause the risk of nozzle *** summary,TPO showed great atomization characteristics for alternative fuel applications.
