    1/9/2007 · Hence, superheater corrosion is an important obstacle that has to be overcome in order to make biomass and waste more competitive as sources for "green power". HTC (the Swedish High Temperature Corrosion Centre) research in this area focuses on understanding why biomass- and waste- burning environments are more corrosive than, e.g., coal fired boilers.

    11/3/2012 · Industrial boilers could, in principle, fire renewable biomass fuels instead of fossil fuels like natural gas, coal, and fuel oil. However, biomass fuels often contain elements such as chlorine, potassium, sodium and sulfur that deposit in ash on the superheater tubes that heat the steam to its maximum temperature.

  • Superheater Corrosion Prevention | Jansen Combustion and Boiler

    Firing boilers at higher rates has, in some cases, led to higher final steam temperature and excessive superheater metal temperatures, which can accelerate corrosive metal loss. JANSEN has developed an engineering analysis approach that helps to predict where superheater corrosion problems may occur and provides the means to design solutions to overcome superheater corrosion.
