Jun 18, 2020 · Process flow of wet flue gas desulfurization process system. The main basic technological process of limestone-gypsum wet flue gas desulfurization is: after the boiler flue gas is dedusted by an electric precipitator and boosted by a booster fan, and then cooled by a flue gas heat exchanger, it enters the absorption tower.

Super Austenitic Stainless Steel in Wet Flue Gas

Of several desulfurization methods, FGD (Flue Gas Desulfurization) is often used. It's a manner to remove the SO2 by using limestone powder. Its desulfurization efficiency can reach above 90%. Whether the desulfurization project can make a success depends on which kind of …

Lime / Limestone Wet Scrubbing System for Flue Gas

After fly ash removal, the flue gas (seen in Figure 1) is bubbled through the scrubber, and the slurry is added from above.The lime or limestone reacts with the SO 2 in the flue gas to create insoluble calcium sulfite (CaSO 3) as in the equations below. Limestone: CaCO 3 (s) + SO 2 (g) → CaSO 3 (s) + CO 2 (g) Lime: Ca(OH) 2 (s) + SO 2 (g) → CaSO 3 (s) + H 2O (l)

Oct 30, 2019 · This boiler design results in a fast mix of air and fuel and encourages rapid heat transfer. The burning environment gives a cleaner burn with reduced quantities of NOx and SO2 in the flue gases. SO2 emissions can be reduced further by introducing pulverized limestone into the combustion chamber.
