Sulfur Content Requirements For Fgd Systems

Wet Flue Gas Desulfurization - Appalachian Power

Scrubbers or flue gas desulfurization (FGD) systems use chemical and mechanical processes to remove sulfur dioxide (SO2) from gas produced by burning coal. Exhaust gas from a coal-fired unit's steam generator is routed through absorber vessels where chemical reactions take place, and SO2 is removed. The illustration below depicts a
