轴流直流式煤粉浓缩器的捕集分离模型

The Collecting and Separating Model of Axial Straight-flowCoal Dust Concentrative Burner

根据气固两相流及边界层分离理论，提出了轴流直流式煤粉浓缩器临界分离粒径及分级效率的数学模型，并给出了实际燃煤颗粒分离特性的模拟计算曲线。

Based on the basic theories of the two phase gas-solid flow and the boundawry payer, this pa- per provides a. mathematical model for the critical separarted particle size and classifitcation effciendcy of the axial straight-flow coal dust concentrative burner. And a result of simulative calculation is given.
