WebExamines flue gas desulfurization (FGD) systems to control SO/sub 2/ emissions from coal-fired electric generating plants. Explains that conventional FGD systems (''wet scrubbers''), which account for as much as 25% of the capital and operating cost of a new 1000-MW plant, have typically experienced severe corrosion problems and plugging and ... Flue-gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO2) from exhaust flue gases of fossil-fuel power plants, and from the emissions of other sulfur oxide emitting processes such as waste incineration, petroleum refineries, cement and lime kilns. See more Since stringent environmental regulations limiting SO2 emissions have been enacted in many countries, SO2 is being removed from flue gases by a variety of methods. Common methods used: • See more Fossil fuels such as coal and oil can contain a significant amount of sulfur. When fossil fuels are burned, about 95 percent or more of the sulfur is generally converted to See more The information in this section was obtained from a US EPA published fact sheet. Flue gas … See more • Incineration • Scrubber • Flue-gas emissions from fossil-fuel combustion See more 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 See more Basic principles Most FGD systems employ two stages: one for fly ash removal and the other for SO2 removal. … See more An alternative to removing sulfur from the flue gases after burning is to remove the sulfur from the fuel before or during combustion. Hydrodesulfurization of fuel has been used for treating fuel oils before use. Fluidized bed combustion adds lime to the fuel during … See more lake tapps counseling
