摘　　要：通过Aspen Plus软件建立模型,研究循环流化床稻壳的气化特性及气化剂空气量(ER值)对4种不同参数的变化的影响趋势。结果表明:当变量因素ER值增加时,气化温度增加,气体产率增加,气化气各组分中CO_(2)和CH_(4)的体积分数减小,N_(2)、CO和H_(2)的体积分数增加,气化气的热值逐渐降低。In this paper,a model was established with ASPEN PLUS software to simulate the gasification characteristics of rice husk in a circulating fluidized bed.The influence trend of gasification agent air volume(ER value)on four different parameters was studied.The results show that with the increasing ER value,the gasification temperature increases,the gas yield increases,the volume fraction of CO_(2) and CH_(4) decreases,while the volume fraction of N_(2),CO and H_(2) increases,and the calorific value of gasified gas decreases gradually.
