Combined with the wet flue gas desulphurization (WFGD) system of 600 MW unit in one power plant

and with the aid of FLUENT software

simulation study on the different combination modes of slurry-circulating pumps under several flue ga loads

i.e.flue gas field in the said tower under different combination modes of different spraying levels

have been carried out.Results shwo that the flue gas flow field in the absorption tower is most uniform in the case of the three spraying levels being in operation under 75% and 50% flue gas load;the flue gas flow field is relatively more uniform in the event of one spraying level being stopped

and the first spraying level combined with the third spraying level being in operation under 70% flue gas load;the flue gas flow field in the said tower is also relatively more uniform in the event of one spraying level being stopped

and the first spraying level combined with the second spraying level being in operation under 50% flue gas load.
