What is a Dew Point? - Definition from Corrosionpedia

At the dew point temperature, water vapor condenses into liquid water. At all times, the dew point temperature is equal to or less than the air temperature. A thorough knowledge about dew point temperature is very important in various industries because moisture can affect corrosion rates. Dew point may also be known as dew point temperature.

Corrosion as a Result of Dew Points and Deliquescent Salts .

dew point temperature is a function of the concentration of gaseous SO 3 and the content of water vapour in the flue gas. In common terminology in the field of coal combustion, the term dew point corrosion is synonymously used with sulphuric acid dew point corrosion. This clear correlation has to do with the chemistry of coal as a fuel.
