  • Nalco Guide to Boiler Failure Analysis, Second Edition > Cold-End Corrosion during Service
    It is also termed acid dew point corrosion, as it is caused by conditions that allow acidic vapors in the flue gas to condense on metal surfaces and cause corrosion.
  • Electrostatic Precipitation
    In addition, ammonia alone has been used on boilers firing high sulfur coal for many years to improve precipitator performance, reduce the acid dew point and corrosion, and in some cases eliminate the ‘blue plume’ from high sulfur trioxide emissions.
