Abstract:

Abstract:In order to solve the blocking and failure problems of the demister of wet flue gas desulfurization system of a 600MW units, the twolayer flat plate type demister was reformed into onestage tubular plus twostage roof type demister. The reformation scheme, the construction period, the project cost and the test result were introduced in detail. After the reformation, the liquid drop content of the flue gas in absorption tower outlet was reduced effectively, and safe operation of the unit
and desulphurization system was ensured.
