The circulating fluidized bed flue gas desulphurization(CFB-FGD) has got more attention from environmental protection, with some advantages of dry process and wet process at the same time, like quick reaction speed and higher efficiencies from wet process, and no waste water discharge, easy handle of FGD by-product and no wet stack from dry process. The circulating fluidized bed flue gas desulphurization(CFB-FGD) technology is based on circulation fluid bed theory, which realize desulfurization through suspension method and letting absorbent float, circulate and fully contact with SO2 in flue gas in absorber tower.
Long equipment service life, less maintenance work
Long contact time, fully contact , high efficiency during FGD process
Easy cooperation control, all loops independent from each other
Strong single tower handling, already applied in large scale power plant
Computer simulating inflow structure at bottom to ensure uniform flow distribution at inlet
No need to do preservative treatment
High availability for SO2 concentration in flue gas
