竖直向上转水平90°弯曲圆管内煤粉浓缩特性研究

Research on the Characteristic of Concentrate Pulverized-coal in the Vertical Upwards Turning Horizontal Bend 90 Pipe

针对竖直向上转水平90弯曲圆管,通过气固两相流的模化,分析了影响分离比的因素,得到最大分离比的位置。对通过这种弯头来实现浓淡分离的燃烧器的优化设计有重要的指导意义。

In the light of the vertical upwards turning horizontal band 90 pipe,through the modeling of gas-solid two-phase flow, the factor of influencing the separation ratio was analyzed, and the position of the maxima separation ratio was found. By using this kind of bend to separate the concentration and dilution, there is signif- icant meaning to design the burner.
