Mechanical dust collectors, often called cyclones or multi-cyclones have been used extensively to separate large particles from a flue gas stream. Mechanical collectors are particulate control devices that use centrifugal force, gravity settling, and inertia to collect pollutants. Mechanical collectors can handle high dust loadings.
In cyclone separators, cyclonic separation method of removing particulates is used. Rotational effects and gravity are used to separate mixtures of solids and fluids.
The cyclone collector is most effective on particles larger than 10 to 15 micron & for fine particles, the collection efficiency drops considerably below 80 %.
