Evaluation Of A Flue Gas Desulphurisation Fgd

The FGD-gypsum used as an adsorbent in this study stems from . a wet limestone FGD-system that operates with a forced oxidation system and re-circulation of water from gypsum slurry filtration to the scrubber. This FGD system includes a number of water streams categorised as FGD water streams: limestone and gypsum slurries, and filtered water.----- • Pretreatment cools and saturates the flue gas and reduces the concentrations of corrosive chloride ions entering the absorber. Typical flue gas tem- peratures range from 290 to 310 F (145 to 155 C) before pretreatment and from 125 to 135 F (50 to 55 C) following pretreatment.1 Fly ash removal may occur in the first stage of a double-stage venturi scrubber (Figure 3).

Fgd Technology For Thermal Power Electrical India

The dry type FGD systems have a lesser water requirement in the absorber as compared to wet limestone FGD. However, the high cost of expensive slaked/quick lime required as reagent in dry FGDs significantly increases operating cost of the systems. Hence, wet limestone FGD has been found to be optimum technology. Initiatives and way forward14. Flue Gas Desulfurization Using Fly Ash Derived from Western Coals.
