近期,我院教师顾丛汇的“Effect of baffle structure on the dynamic transportation behavior of s-liked biomass fuels in a rotating drum”研究成果在《ENERGY SCIENCE & ENGINEERING》上发表。

 

论文简介如下:

The booming progress of biomass fuels in the enhancement of energy sustainability has been witnessed over the past few decades. Drying or moisture content reduction is a critical pre-treatment step for the efficient utilization of wet biomass fuels whose improvement requires this study to focus on the effect of the transportation behavior of biomass fuels inside drying facilities. Experiments were performed under a variety of operating conditions in order to determine the residence time distribution (RTD) and flow characteristics of s-liked biomass fuels in the process of transportation. A series of experiments are carried out in a rotary drum with different baffle structures, a length of 1,850 mm and a diameter of 770 mm. Meanwhile, s-liked and CO2 expanded biomass particles were taken as standard and tracer materials. RTD, scattering and fallout angles are measured and studied under the conditions of different baffle heights (64~184 mm), numbers (2~8), installation slopes (70o~110o), rectangular bend heights (24.8~62.5 mm) and bend slopes (90o~150o). The Taylor model can appropriately estimate the mean residence time (MRT) of particles in a rotating drum with variety of baffle structures, such as baffle height, number and bend slope.
