Abstract: The flue gas cooling tower technology was adopted in 2×350MW heat supply unit of Huadian Tianjin Junliangcheng Power Generation Corporation Limited project phase V. The corrosion mechanism of flue gas cooling tower was analyzed in detail. It is pointed out that adoption of anticorrosive coating is practical, domestic anticorrosion method. The principle for choice of anticorrosion system was introduced, and the problems needing attention in anticorrosion construction were put forward, so the anticorrosion quality of the cooling tower was raised fundamentally.

Key words: flue gas cooling tower, anti-corrosion system, coating
