a. Particulate collection. Cyclones are used as
par-
b. Pre-cleaner. Cyclones are primarily used as
pre-
ticulate collection devices when the particulate dust is
coarse, when dust concentrations are greater than 3
stoker fired coal burning boilers where large coarse
grains per cubic foot (gr/ft3), and when collection effi-
particles may be generated. The most common applica-
ciency is not a critical requirement. Because collection
tion is to install a cyclone ahead of an electrostatic
efficiencies are low compared to other collection
precipitator. An installation of this type is particularly
equipment, cyclones are often used as pre-cleaners for
