Flue Gas Desulfurization - CS Indonesian Thermal Coal Index

Flue Gas Desulfurization. Flue gas desulfurization is commonly known as FGD and is the technology used for removing sulfur dioxide (SO2) from the exhaust flue gases in power plants that burn coal or oil to produce steam for the steam turbines that drive their electricity generators. Sulfur dioxide is responsible for acid rain formation.
