Cyclone Dust Separators are devices often used to filter solid particles from flue gas. Such cyclones are supposed to filter as
much particulate matter from the gaseous stream as possible. At the same time, they should only introduce minimal pressure loss
to the system. Hence, collection efficiency has to be maximized and pressure loss minimized. Both the collection efficiency and
pressure loss are heavily influenced by cyclone geometry. In this paper, we optimize inner geometrical construction of
multichannel cyclone to up cleaning efficiency parameter. This study shows how geometry involves cleaning efficiency. At air
flow rates from 12 m/s to 18 m/s after researches the optimal cleaning efficiency achieved in the three level cyclone at 16 m/s
average air flow rate in cyclone channels, when the treated air is polluted with 20
