Vinyl Ester Glass Flake Coatings for FGD /Chimney
Flue Gas Desulphurization (FGD) units in power plants are exposed to aggressive operating environments. The acidic and high-moisture flue gases produced during the scrubbing process can significantly degrade the metallic structures of scrubbers, ducts, tanks, and chimneys if left unprotected. To ensure long-term performance and durability of these critical systems, a specialized high-performance coating is essential.
Understanding Corrosion Challenges in FGD Systems
FGD units play a vital role in reducing harmful emissions from fossil fuel-based power plants. In this system, a mixture of lime and water reacts with sulphur dioxide in the flue gas to form calcium sulphate (gypsum), which is separated, and the treated gas is released through the chimney. However, internal components of the FGD system — including scrubbers, absorber towers, ducts, chimneys, and recirculation tanks — are continuously subjected to a highly corrosive atmosphere due to:
- Constant exposure to acidic gases and chemical slurries
- Elevated operational temperatures
- Chloride attack
- Mechanical wear and erosion
- High humidity and permeation
