【摘要】 基于对3套8.53MPa双通道喷嘴渣油气化装置普遍存在的工程现象的思考,组织了模型气化炉冷态试验。测试了3种模型在6种射流速度下的停留时间分布,7种模型在2种射流速度下的速度分布。给出了停留时间分布密度函数、无因次半速度半径轴向增长、径向射流最大速度轴向衰减和径向速度分布计算公式。更多还原

【Abstract】 The common behavior of three sets of residual oil gasifier with twin - fluid nozzle at 8. 53MPa,was commercial-scale studied and an experiment of cold model was performed. The residence time distribution for three models of gasifier at six jet velocities and the velocity profile for seven models of gasifier at two jet velocities were measured.The equations of the density function of residence time distribution, the axial growth of the velocity half - radius, the axial decay of radial maximum jet velocity and radial profile of jet velocity were obtained.更多还原
