cost-effective solution for so2 emissions reduction with fork density .

Flue gas desulfurization (FGD) is a technology used for removing sulfur dioxide (SO2) from the exhaust flue gases emitted by coal- or oil-burning power plants. The SO2 is created when the power plants burn coal or oil to produce steam to power the steam turbines that drive the electricity generators. The tall flue gas.
