Question:medium

For the removal of sub-micron particulate matter (\(<1~\mu\mathrm{m}\)) from flue gases, which of the following devices generally provides the highest collection efficiency?

Show Hint

Efficiency of particulate control devices: \[ \boxed{ \text{ESP} > \text{Wet Scrubber} > \text{Cyclone Separator} > \text{Gravity Settling Chamber} } \] ESPs are best suited for very fine particles.
