  • 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.
