For a typical coal-fired power station, flue-gas desulfurization (FGD) may remove 90 percent or more of the SO 2 in the flue gases. History. Methods of removing sulfur dioxide from boiler and furnace exhaust gases have been studied for over 150 years. Early ideas for flue gas desulfurization were established in England around 1850.
Exhaust flue gas is drawn from the boiler and forced into an absorber tower by a booster fan. Once inside the absorber tower, the gas flows upwards through a dense shower of lime or limestone slurry. The slurry absorbs the Sulfur Dioxide (SO2) in the flue gas. The absorption

EPA-452/FKefid4 Air Pollution Control Technology Fact Sheet EPA-CICA Fact Sheet Flue Gas Desulfurization1 Name of Technology: Flue Gas Desulfurization (FGD) - Wet, Spray Dry, and Dry Scrubbers Type of Technology: Control Device - absorption and reaction using an alkaline reagent to produce a solid compound.
Being an inert gas, Nitrogen protects against corrosion of inner walls of boiler tubes, condensers, and wetted parts within Power Plant applications by displacing oxygen and other residual molecules. In the past, high-pressure bottles as well as bulk liquid tanks have been the primary source for Nitrogen, but new technology has come into play.
Mar 16, 2016 · No, boilers in operation today do not boil water (myth number one bites the dust!). The term boiler is a carryover from the past when steam boilers were common, which boiled water to make steam. Todays boilers are water heaters and typically use natural gas. Most can heat water in a range from 145-190 degrees, depending on the
