    Most FGD systems employ two stages: one for fly ashremoval and the other for SO 2 removal. Attempts have been made to remove both the fly ash and SO 2 in one scrubbing vessel. However, these systems experienced severe maintenance problems and low removal efficiency. In wet scrubbing systems, the flue gas normally passes first through a fly ash removal device, either an electrostatic precipitator or a baghouse, and then into the SO 2-absorber. However, in dry injection or spray drying operations, the S
