Degradation of protective coatings in steel chimneys of flue gas desulfurisation system
This paper presents problems associated with corrosion of steel stacks and changes in philosophy of corrosion protection when implemented into flue gas desulphurization systems. In-situ tests were taken by means of electrochemical impedance spectroscopy at the stack which discharges flue gas before wet lime/limestone desulphurization. A very quick electrolyte absorption by the spherical infill vinylester coating was found using the electrochemical impedance spectroscopy. An analysis of destruction shows a joint effect of mechanical and corrosion factors on the poor resistance of the coating. The poor resistance of the coating is also connected with the method of chimney construction and coating application.
