Directing against the properties of flue gas after wet desulfuration system in Beilun Power Generating Company （Beilun Power Plant）

simulation has been carried out in the laboratory

the influence of different desulfuration efficiency and different concentration of sulfuric acid upon the corrosion rate of several metals being studied. The results of study show the flue gas after desulfuration affects strongly upon the 10CrMnCuTi

it is neccessary to carry out anticorrosive treatment for the chimney after the wet desulfuration system. Under acidic condition

the corrosive rate of four metals is listed sequentially as below: Q235A>10CrMnCuTi>0Cr18Ni19>0Cr1>Ni12Mo2

Cl and F can greatly accelerate the corrosion; the corrosive capability of simulated condensate on chimney is very strong to 10CrMnCuTi

but Ti is basically not corroded.
