Factors Affecting Atmospheric Corrosion
Factors Affecting Atmospheric Corrosion. The most important factor in atmospheric corrosion overriding pollution or lack of it is moisture either in the form of rain dew condensation or high relative humidity (RH). In the absence of moisture most contaminants would have little or no corrosive effect.

Prediction of Acid Dew Point in Flue Gas of Boilers
The temperature of flue gas should be controlled to be higher than the acid dew point to avoid fouling and corrosion of heating surfaces in the second pass of boilers. Decreasing the temperature of flue gas in boilers is one of the most effective ways to improve thermal efficiency enhance electrostatic precipitator efficiency and decrease water consumption of the desulfurization tower.
