Hydrocyclones for flue gas desulfurization FGD power applications
FGD: KREBS hydrocyclones are used to classify limestone ball mill discharge in the reagent preparation area of wet flue gas desulfurization (WFGD) scrubbers in coal fired power plants. In the forced oxidation process,the limestone reagent reacts with absorbed SO2 from the boiler exhaust, forming gypsum as a byproduct. Gypsum slurry from the absorber is pumped to KREBS hydrocyclones to be dewatered from about 15-20% solids by weight to approximately 50% solids by weight. FLSmidth also offers Technequip knife gate valves and millMAX pumps for FGD applications.
