Flue-gas desulfurization - Wikipedia

Flue-gas desulfurization (FGD) material is a product of a process typically used for reducing SO 2 emissions from the exhaust gas system of a coal-fired boiler. The physical nature of these materials varies from a wet sludge to a dry, powdered material depending on the process.

Manual: Flue Gas Desulfurization Inspection and …

In the bypass reheat system (Figure 2.4-8c), a portion of the hot flue gas from the boiler bypasses the absorber(s) and is mixed with scrubbed flue gas. Two variations of this method are "hot-side" bypass, in which the flue gas is taken upstream of the boiler air preheater and "cold-side" bypass, in which flue gas is taken downstream of the boiler air preheater.

31/12/2020 · Mechanism of Cold end corrosion The sulfur content in the fuel is the major cause for the cold end corrosion. When the sulfur burns in the boiler, it forms sulfur dioxide. Which is relatively harmless. However, the SO 2 is further oxidized to form SO 3 as a result of the catalytic effects of vanadium pentoxide(V 2 O 5) or iron oxide(Fe 2 O 3) in the fuel itself and.
