USER GUIDELINE FOR FLUE GAS DESULFURIZATION

Fixated FGD scrubber material is generated, dewatered, and stabilized at coal-burning power plants that require scrubbing of flue gas to reduce sulfur dioxide emissions. Plants that require scrubbing typically burn either medium- or high-sulfur coal. The majority of coal-fired power plants that are equipped with FGD scrubber systems, dewater and stabilize FGD scrubber sludge for beneficial use or landfilling.

fluorides), wet / dry and crevice conditions, and gas velocity all must be considered in defining the corrosivity of the environment. Dew Point The conditions inside the scrubber (e.g., acid concentration) determine the temperature at which acids condense. Condensation of acids normally accounts for most of the corrosion encountered in FGD systems.

Flue Gas Desulphurisation (FGD) Policy Measures

Flue gas desulphurisation (FGD) is a technology used to remove sulphur dioxide (SO 2) from the exhaust flue gases of fossil fuel power plants.Fossil fuel power plants burn coal or oil to produce steam for steam turbines, which in turn drive electricity generators.

Comparing evaporation and bioreactors for FGD wastewater

A variety of flue gas desulfurization (FGD) processes is available, including wet scrubbers, dry sorbent injection, spray dryer absorbers and circulating dry scrubbers. While, as the name implies, FGD is primarily designed to remove sulfur oxides, the processes also remove other acid gases such as hydrogen chloride, and in some cases also mercury.
