An Overview of CoalFired Power Plant FGD Wastewater Treatment Coal Combustion and Emissions Control. Coal, the primary resource for producing electricity, generates over half the nation's electricity. Balancing a dependence on foreign oil, coal offers over 274 billion tons of untapped supplies enough to energize America for 250 years.
The FGD systems are designed to remove SO 2 from flue gas generated by the boiler. The flue gas enters the absorber just above the reaction tank liquid level and rises upwards. As it rises, it contacts fine droplets of recycled limestone slurry, which absorb the SO 2. The clean gas is then passed through two stages of mist eliminators to remove slurry and water droplets.

Wet scrubber FGD plants play a critical role in reducing emissions of sulphur dioxide from coalburning power stations. However, the abrasive and corrosive wet limestone slurry used in this process demands pumps of high levels of reliability.
Fluegas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO 2) from exhaust flue gases of fossilfuel power plants, and from the emissions of other sulfur oxide emitting processes ( trash incineration) Wet scrubbing using a slurry of alkaline sorbent, usually limestone or lime, or seawater to

Oxidation of the slurry sorbent causes gypsum (calcium sulfate) scale to form in the absorber. Limestone forced oxidation (LSFO) is a newer process based on wet limestone scrubbing which reduces scale. In LSFO, air is added to the reaction tank which oxidizes the spent slurry to gypsum.
Flue Gas Desulfurization Wastewater Treatment Primer. Coal contributes acidic gases — such as chlorides, fluorides, and sulfate — as well as volatile metals, including arsenic, mercury, selenium, boron, cadmium, and zinc. The limestone contributes iron and aluminum (from .
