摘　　要：介绍７种不同规格容器、６种工况下的停留时间分布测试结果，定性地分析了影响停留时间分布的因素，诸如射流速度、高径比、筒体直径与喷嘴直径比、出口阻力等。研究表明，德士古气化炉基本上趋于全混流，约有５０％左右的物料在平均停留时间之前离开炉膛，存在短路，停留时间不足一秒，已见物料逸出炉外。he resident time distribution curres are established at six jetting velocities and seven vessels simulating residual oil gasifier.Such factors as jetting velocity,height/diameter ratio of gasifier and the ratio of cylinder diameter to burner di-ameter and exit resistance,which affect resident time distribution are analyzed. The study shows texaco gasifier approach-es an ideal stirred tank,that about 50/of the feed leaves the gasifier before the average resident time,and that the resi-dent time is less than 1 second,which means the feed was least because of by-pass.
