摘　　要：通过脉冲示踪法,研究气液两相循环流化床停留时间分布,并从整个循环体系的停留时间分布曲线中,分离出提升管的停留时间,建立了数学模型,并进行模拟.Fluid residence time distributions of two-phase circulating fluidized bed were determined by using pulse tracer method, and RTD curves in riser were separated from RTD curves in whole circulation system. RTD curves were analyzed and mathematical model of fluid RTD was made.

关 键 词：气液两相 停留时间分布 循环流化床
