Abstract: The absorption tower system is the key subsystem of FGD device, which needs to consume a lot of material and energy
during operation. At present, the operation parameters of the slurry circulating pump, such as the operation combination mode and
the slurry pH value control, have much room for improvement. If appropriate methods can be used to optimize them, the operation
cost can be greatly reduced. This paper summarized the latest research results on the optimization of operation parameters in
China, and put forward the problems existing in the operation optimization process of the absorption tower system at present, the
optimization of experimental method could not further reveal the operation mechanism of the absorption tower system; the
optimization of theoretical method was still based on simulation, and it needed further research to be extended to specific projects.
By studying the latest research status of absorption tower system operation in domestic thermal power plants, it can be understood
to provide reference for further reducing energy consumption of absorption tower system operation.
