Analysis on reasons of demister blockage of 600MW unit wet FGD systeme and countermeasures

Abstract

Abstract: The working theory of the plate type demister and the category of its scaling were introduced. Aiming at the demister blockage fault, which often occurred in the wet FGD system of the 2×600MW unit of Hebei Datang International Wangtan Power Generation Company Limited, combining with the operation experience of the power plant FGD system obtained for 5 years since it was put into operation, the two main factors influencing on demister blockage and scaling were analyzed; and concrete countermeasures were put forward.

Key words: 600MW unit, wet flue gas desulphurization (wet FGD), demister, blockage, scaling, measure
