摘要

Solid particle flow characteristics and biomass gasification in a clapboard-type internal circulating fluidized bed reactor were investigated. The effect of fluidization velocity on particle circulation rate and pressure distribution in bed show that fluidization velocities of the high and low velocity zones are the main operational parameters to control the particle circulation, and for different velocities of the low velocity zone maximums of internal circulation rates exist and almost come within certain range of the velocity of the high velocity zone, in the experiment that is u_H/u_(mf)=2.2～2.4 for rice husk and u_H/u_(mf)=3.5～4.5 for quartz sand. In gasification experiment, air equvalence ratio is the main control parameter. Rice husk gasification gas has its highest heating value of around 5000 kJ/m~3 when ER=0.22～0.26, and sawdust gasification gas reaches around 6000～6500 kJ/m~3 when ER=0.175～0.24. The gasification efficiency of rice husk reaches the maximum of 77% at ER=0.28, and the value of sawdust reaches the maximum of 81% at ER=0.25.
