In order to solve the problems happened during the operation of seawater flue gas desulfurization(FGD) equipment

such as poor adaptability of the equipment on sulfur content in coal

high energy consumption of running

corrosion on the device and so on

several countermeasures were proposed as follows:if the sulfur content in coal is under designed condition

it is better to increase the packing height

install deflector in flue duct

and add fixed filler device etc.to strengthen the seawater-gas contact efficiency;while when the sulfur content is out of the designed range

increasing the liquid-gas ratio and adding desulfurization additives can be adopted to improve the system's adaptability.
