| Abstract: |
| In order to predict the influence of operating temperatures on cyclone performance, an experimental investigation was conducted on particle separation in a reverse flow, tangential volute-inlet cyclone separator, which has a diameter of 300 mm, with air heated up to 973 K. The test powder silica has a mass median diameter of 10 _ and the inlet velocity ranges from 12 to 36 m/s. Both the separation efficiency and pressure drop of the cyclone were measured as a function of the inlet velocity and operating temperature. It is shown that at the same inlet velocity, both the separation efficiency and pressure drop decrease with the increase of temperature. Besides, the optimum inlet velocity，at which the cyclone has a highest separation efficiency, tends to increase with the rise of temperature. |
