Forced Air Oxidation In Wet FGD | Hoffman & Lamson

Most FGD systems employ two stages: fly ash and SO 2 removal. Individual FGD systems vary considerably. In general, flue gas from the boiler first passes through a particular emission removal device then into the absorber. The gas passes through the entertainment separator to a reheater and is finally exhausted out of the stack.

For horizontal FGD designs, the fresh slurry (recycle and makeup streams) is often introduced at the last, or rear, stage of the absorber where the SO 2 content of the gas stream is lowest. The slurry contacted in the last stage is pumped forward to the next stage. This way, the slurry "flows" countercurrent to the gas flow.
