1. There are no moving parts to break down.
2. For abrasive dusts, units can be constructed in heavy plate or special materials.
3. Known areas of heavy wear can be designed for easy replacement.
4. Temperature is not necessarily limiting. Cyclones can operate at high
   temperatures with special construction.
5. For operation at very high temperatures, cyclones can be refractory
   lined, and constructed from special steels.
6. Efficiencies are consistent and will remain so throughout cyclone life.
7. Dust is normally collected dry.
8. The cyclone can handle a wide variety of dusts and materials.
9. Pressure drop is constant for a given duty.
10. Cyclones can be used for high gas pressure operation.
11. Increasing inlet concentration does not lower overall efficiency per cent.
12. Considerable flexibility of gas throughput without upsetting efficiency.

Important Factors To Consider For Cyclone System Selection

1. The volume and nature of gas to be cleaned, including chemical analysis.
2. Type and nature of dust to be removed
3. Particle size range of solids.
4. Particle specific gravity (not bulk density).
5. Solids loading in gas streams.
6. Chemical analysis of solids if necessary.
7. Explosion or fire risk.
8. Gas operating temperature and pressure
9. Design temperature and pressure.
10. Gas operating density.
11. Erosive character of solids.
12. Build-up or "stickiness" of solids either cold or at temperature.
13. Pressure loss limitation.
14. Degree of overall efficiency required.
15. Space available for installation.
16. Disposal of collected solids.
17. Economic factor.
