Wet FGD system, also called a wet scrubber system, is based on the principle that limestone, in the form of slurry is brought into contact with the flue gas which absorbs the SO2 in it. Process water requirement for a 1000MW coal based thermal powerplant is approximately 100 TPH per FGD.
Wet flue gas desulfurization system (FGD) comprises four main processes flue gas handling, reagent (limestone) handling and preparation, absorber and oxidation, and secondary water and gypsum handling. Wet freshwater flue gas desulphurization equipment uses limestone .
Abstract: In 2014 limestone desulfurization, denitrification latest technology 1 limestone slurry preparation system The limestone (particle size ≤20mm) into the discharge hopper, the feeder, bucket elevator to the inner limestone steel silo, and then by weighing feeder and belt conveyor to the mill made within a wet ball mill slurry ...
If required, classifier grits can be evacuated for another classification in a downstream Pfeiffer separator and separated into limestone sands ( to mm) in screening machines. Pulverized limestone is used above all as filler and for flue gas desulfurization. Limestone sand is used in building materials.
