Coal-fired boiler emissions are usually controlled by one of the following methods: (1) a high velocity spray tower for flue gas desulfurization (FGD) installed downstream of a dry electrostatic precipitator, or a baghouse which removes the fly ash. Lime or limestone is used for neutralization; (2) a high energy venturi scrubber for fly ash removal followed by a high velocity spray tower for FGD. The alkaline ash, with lime or limestone added is used for neutralization and saves alkali costs. Peabody Process Systems has been investigating an additional system comprising a low pressure drop gas quencher and an FRG spray tower with a Wet Tubular Precipitator (WTP) installed on top of the spray tower. The alkalinity in the ash, augmented with lime or limestone, can be used for neutralization if the full fly ash load goes into the tower.
