| Abstract: | The unsteady characteristic of gas-solid flow in a Stairmand HE type cyclone separator were numerically studied by using the FLUENT software combined with the CAE method.In simulation,the R-K-ε model was adopted to calculate the gas flow,the Discrete Phase Model（DPM）was adopted to calculate the particle flow,the effects of the cyclone＇s structure and its operational parameters on dust separation efficiency,press-drop,and abrasion was also analyzed,and a new cyclone structure which had such performance characters as a relatively high separation efficiency,low running press-drop as well as light abrasion for a 4t/h coal boiler was obtained. |

| Keywords: | cyclone separator numerical simulation structure parameter dust separation efficiency press-drop |
