Abstract

The purpose of this research is to analyze the molding quality and energy consumption of biomass pellet fuel under three compression methods of uniform speed, uniform deceleration and superposition vibration. This article established a discrete element model of sandy shrub particles uniaxial compressed. The simulation results shows that the compression method has no significant influence on the maximum compression force. The degree of particle aggregation and deformation is better than the other methods in vibration compression method. The forming quality of vibration compression method is better than the other methods. The particle bonding effect is poor in uniform compression method. This research calculates the work of uniform speed, uniform deceleration and superposition vibration by using numerical integration through the force-displacement data. They are respectively 25.898 J, 24.496 J, 28.019J. This result shows that vibration compression method consumes the most energy, the uniform deceleration compression method is the least. The total energy of particles under different compression methods can also indicate the accuracy of this conclusion. The simulation results can provide a theoretical basis for the selection of compression methods in the process of biomass solidification.
