液排渣粉煤燃烧装置的几个流体流动问题

Some Questions of Fluid Flow in the Entrained Slagging Coal Powder Combustor

摘要: 分析了液排渣粉煤燃烧器内的流体流动问题,着重分析了中心回流区及其作用。研究了影响中心回流区的主要因素。给出了燃烧室内的轴向速度和切向速度的试验结果。对存在的一些问题进行了讨论,并提出了改进意见。

Abstract: The flow of fluid in the entrained slagging coal powder combustor are analysed. Specially, the center reflux area and its effects on the flow of fluid slag are analysed. The main factors which affect the center reflux area are investigated. The experimental results of the axal velocity and the tangential velocity in combustor have been given. Some suggestions for improvement have been made.
