The "Lime stone FGD Scrubbers: User''s Handbook" is intended for use by utility project managers and project engineers. It provides guidance in selection, installation, and operation of a limestone FGD system, covering all phases from inception of the project through design, procurement, operation, and maintenance of the system.
Flue gas desulfurization scrubbers have been applied to combustion units firing coal and oil that range in size from 5 MW to 1500 MW. Scottish Power are spending £400 million installing FGD at Longannet power station, which has a capacity of over 2 GW. Dry scrubbers and spray scrubbers have generally been applied to units smaller than 300 MW.

FGD SCRUBBER MATERIAL Material Description. ORIGIN. The burning of pulverized coal in electric power plants produces sulfur dioxide (SO 2) gas 1990 Clean Air Act and its subsequent amendments mandated the reduction of power plant SO 2 emissions. The Best Demonstrated Available Technology (BDAT) for reducing SO 2 emissions is wet scrubber flue gas desulfurization (FGD) .

Oct 13, 2015· A critical component of FGD systems, scrubber recycle pumps recirculate limestone slurry from the absorber vessel back to the spray nozzles. Initially, the sizes of these pumps were relatively small, and they had a satisfactory "meantimebetweenrebuilds" (MTBR) of 8–10 years.
Scrubber and limestone systems SKF. Due to increasing regulations, many coalfired plants are capturing harmful SO2 gases with a Flue Gas Desulphurization (FGD) system. The most common is the wet scrubber/limestone system, which can remove more than 95% of flue gas SO2 and produce useful gypsum byproducts in the process. Get Price
