In the past, industrial plant operators tended to fit mainly cyclones. More recently, fabric filters have increased their market share in industry in the various processing fields. Cyclones are robust technologies that can deal with the cyclic operation and load changes, which is quite common in these types of plants. However, their efficiency is moderate when compared with ESP or fabric filtration. A cyclone is a cylindrical vessel, usually with a conical bottom. The flue gas enters the vessel tangentially and sets up a rotary motion whirling in a circular or conical path. The particles are 'thrown' against the walls by the centrifugal force of the flue gas motion where they impinge and eventually settle into hoppers.
Removal efficiency 75-99%
