  • Thermal Fatigue of Boiler Tube - Steel Image

    Cracking of the boiler tube had occurred by corrosion fatigue. The difference in thermal heating/expansion of the surrounding wall plates versus the water-filled boiler tube had applied high thermal strains onto the tube during rapid temperature changes (i.e. starts/stops, TRIPS, operating issues, etc.). Repeated thermal cycling had resulted in theLearn More

  • Water Handbook - Preboiler & Industrial Boiler Corrosion

    Examples of this type of failure include cracks in boiler components at support brackets or rolled in tubes when a boiler undergoes thermal fatigue due to repeated start-ups and shutdowns. Thermal fatigue occurs in horizontal tube runs as a result of steam blanketing and in water wall tubes due to frequent, prolonged lower header blowdown.Learn More

  • Finding the Root Cause of Boiler Tube Failures

    Symptoms: Aggressive localized boiler tube corrosion and loss of tube wall.Pits can act as stress-concentration sites which can be initiation points for stress-related corrosion mechanisms. Causes: Oxygen pitting occurs with the presence of excessive oxygen in boiler water.It can occur during operation as a result of in-leakage of air at pumps, or failure in operation of preboiler water Learn More

  • An overview of problems and solutions for components

    Dec 21, 2017 · Boilers can be basically classified into water tube boilers, fire tube boilers, packaged boilers, fluidized bed combustion boiler (FBC), Pulverized fuel boiler and waste heat boilers. In water tube boilers, the water to be heated flows in the tubes and the combustion gases flows around the tubes, thus converting the water into steam.Learn More

  • TGN-PE-03 Cracking in Fire Tube Boilers - ATHRA

    Virtually all cracks occur at welded joints or at openings. The root cause is corrosion fatigue with thefatigue cycling being thermally driven. Over 100 boilers in Australia suffered this type of cracking inthe 1950 – 1975 period. The change to natural gas firing initially accelerated the rate, but it has sincefallen. UK inspection data from 2001 showed that 2% of fire-tube boilers inspected had servicedefects – mainly cracks.Learn More
