Experimental Study and Motion Simulation of Biomass Particles in Suspension Fluidized Unit

摘要

The research and application of biomass have been paid more and more attention. In this paper, a new experimental device is designed by oneself. The corn cob and rice husk are carried out separately on a separate and mixed flow of fluid. Using FLUENT software, the gas-solid movement of the particle was simulated by Euler two-fluid model and mixture pressure, particle concentration, particle velocity was simulated on the bed. The experimental study results show that biomass can be fluidized. The effect of fluidization of biomass particles is very poor, and a certain proportion of inert particles must be added to achieve a better fluidization effect. In the mixed fluidization of biomass and quartz sand, the mass fraction is 20 ～ 30%, and the fluidization effect is good. When suspended fluidization enter into the stable transport state, the bed particle concentration is basically the same. In the central bed, fluidization effect is not satisfactory, it can improve the layout design of the wind board.
