in agreement with experiments. In
other words, uniflow cyclones can
achieve higher efficiencies per volume
than standard cyclones if the
available pressure drop is low. Furthermore,
independent of any restriction
regarding volume and pressure
drop, the performance data of both
cyclone types approach each other
with decreasing gas-volume flow and
increasing pressure drop, as well as
particle size and particle density of
the solids feed. Those results transfer
to multicyclones systems consisting
of many parallel cyclone cells.
