Microstructure contradistinction for indirect/direct desulfurization product layer of limestone particle in coal-fired flue gas
The micro morphology of limestone sorbent is a key for improving the SO2 removal efficiency in the coal-fired power plant. The tube furnace system was built for imitating the indirect desulfurization reaction in traditional boiler atmosphere (65%N2, 15%CO2, 4.7%O2, 15%H2O, 0.3%SO2) and the direct desulfurization reaction in oxygen-fired atmosphere (80%CO2, 4.7%O2, 15%H2O, 0.3%SO2). The reacted ...
متن کاملFlue gas desulfurization
Flue gas desulfurization is commonly known as FGD and is the technology used for removing sulfur dioxide (SO2) from the exhaust combustion flue gases of power plants that burn coal oroil to produce steam for the turbines that drive their electricity generators. The most common types of FGD contact the flue gases with an alkaline sorbent such as lime or limestone. As sulfur dioxide is responsibl...

متن کاملUsing bromine gas to enhance mercury removal from flue gas of coal-fired power plants.
Bromine gas was evaluated for converting elemental mercury (Hg0) to oxidized mercury, a form that can readily be captured by the existing air pollution control device. The gas-phase oxidation rates of Hg0 by Br2 decreased with increasing temperatures. SO2, CO, HCl, and H2O had insignificant effect, while NO exhibited a reverse course of effect on the Hg0 oxidation: promotion at low NO concentra...
متن کاملBench- and Pilot-Scale Studies on Mercury Removal by Potassium Iodide in Coal-Fired Flue Gas
Mercury (Hg) is a toxic air pollutant with coal-fired utility plants being the largest anthropogenic Hg emission source in the United States. The extent that Hg can be removed from power plants using conventional air pollution control devices (APCDs) is significantly affected by Hg speciation in flue gas. Oxidized Hg (Hg) is preferable to elemental Hg (Hg) in that Hg is less volatile and solubl...
