-
摘要: 分析了液排渣粉煤燃燒器內的流體流動問題,著重分析了中心回流區及其作用。研究了影響中心回流區的主要因素。給出了燃燒室內的軸向速度和切向速度的試驗結果。對存在的一些問題進行了討論,并提出了改進意見。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.
