Abstract: Abstract:In present, the chimneys of domestic power plants with desulphurization system were damaged lightly or seriously due to the reasons of the anticorrosion material quality, the construction quality and so on. The operation condition of the chimney for the semidry desulphurization system and the characteristics of the flue gas were analyzed. According the analysis, the structure form of the chimney for semidry desulphurization system and the anticorrosion scheme were selected and analyzed. The results of this paper are helpful to ensure the chimney to play its role normally during rational designed life and the unit to operate normally.
