LIMESTONE IN FLUE GAS DESULPHURIZATION IN OXYGEN .
Due to its significant influence on the success of dry flue gas desulphurization methods, the calcination process is one of the key elements of the desulphurization process. It can be described by the following chemical reaction: CaCO3 → CaO + CO2 (1) The calcium carbonate calcination temperature is closely related to the partial pressure of CO2.

dry flue gas desulfurization effect particle resistivity
EFFECTIVE DRY DESULFURIZATION BY A POWDER . In a process of flue gas desulfurization by use of dry limestone, the smaller the particle size of the limestone, the higher is the SO2 conversion expected. In a powderparticle fluidized bed (PPFB) fine particles less than 40 μm in diameter fed into the bed are fluidized with coarse particles.
Flue gas desulphurization detailed process
Fluegas 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 sulphur oxide emitting processes. 8. It is a control device that absorbs and react using the alkaline reagent to .
