Module 13: Cyclone
  Lecture 41: Equipment, theoretical cut diameter, efficieny
 
 
  • All particles having diameter will have equilibrium radius within 0.5 do so that they will be carried away with the gas.
    All particles having diameter will be captured in cyclone.
  • Cyclones are very effective in removing particles from gas. Disadvantages are large flow rate required and large pressure–drop because of the tortuous path of the gas.
  • gas velocity at the inlet
  • Separation factor of a cyclone, s is defined as
  • Cyclones are effective typically for particle size
  • Efficiency (capturing) of cyclone,

Design graphs are available to calculate the efficiency.
