Scrubber and limestone systems - SKF. Due to increasing regulations, many coal-fired 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 by-products in the process. Get Price

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.
Limestone fgd (flue gas desulfurization) scrubbers: user's handbook.These experiments have been quite successful, due to certain properties of the limestone impurity that makes it easier to remove by this method than was expected. Read more
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 emissions.The 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) .
