Flue Gas - an overview | ScienceDirect Topics
The flue gas enters the lower part of the desulfurization absorption column under the action of the booster fan after being dusted by the dust collector. In the rising process, it comes into full contact with the falling limestone slurry sprayed by the spray. SO 2 in the flue gas is absorbed by the slurry and falls into the slurry pool at the bottom of the column.
