Thermal Power Plant Coal Handling Plants

Introduction. Flue-gas desulfurization (FGD) is the removal process of sulfur dioxide (SO2) from flue gases. Sulfur dioxide in gases is produced by the combustion of fossil fuels and many industrial processes such as gasoline refining as well as cement, paper, glass, steel, iron and copper production.
