Abstract:Take capacity expansion reformation of flue gas desulphurization system of a certain 600MW unit as an example,this paper introduces comparison and selection of capacity expansion reformation of desulphurization in the high sulphur district in order to adapt to the change of sulfur content rate in coal and national emissions requirements.This paper also analysis the implementation of the original desulphurization system,which brings reference value to similar plant transformation.

Key words: Keywords:600MW unit, high sulphur coal, single tower desulphurization, capacity expansion
