• The structure that the swirling flow center accords with the shape center is desirable.
• The structure that the airflow rate decreases in the dust collection section is desirable.
• Conical cyclone performance is improved by installing an apex cone.
• Installing the stabilizer to the conical cyclone is not valid.
• CFD (LES) is effective for reproducing flow field inside the conical cyclone.
We investigated the design of relatively large cyclones with large amounts of airflow containing dust that are used in actual dust collection plants. In order to obtain basic data on the design of conical cyclones with a Reynolds number of approximately 8.9 × 105, we compared the fluid analysis results with the experimental results on dust collection and particle classification performance for conical cyclones to which apex cones and stabilizers were attached. Then, we elucidated the relationship between the flow conditions inside the conical cyclone with a Reynolds number of 8.9 × 105 and dust collection and particle classification performance.
