Finding the Root Cause of Boiler Tube Failures

The high corrosion rate in biomass and waste-fired boilers is tied to the ash composition of those fuels. The ash from the fuel forms deposits on the heat exchanger tubes of the boilers.

Corrosion of superheater materials in a waste-to-energy

Jan 01, 2013 · Superheaters in waste-fired boilers normally operate at steam temperatures between 350 °C and 500 °C, and deposit-induced corrosion is considered the major cause for rapid material degradation, as chlorides are deposited on the tubes. One possible strategy to improve energy conversion efficiency by mitigating superheater corrosion is via alloy modification.

Causes & Influencing Factors of Boiler Shutdown Corrosion

heat transfer is a result of non-uniform gas flow or non-uniform steam distribution in the superheater. Significant causes of failure in superheaters are localized prolonged heating, creep damage, thermal fatigue, excessive thermal stresses, water and fireside corrosion, erosion, etc. General modes of

Waste Heat Boiler - an overview | ScienceDirect Topics

The corrosion of superheaters and reheaters in fossil fired boilers can be related to both fire and steam side conditions. Oil fueled boilers exhibit ash corrosion by low melting point slags of vanadium, sodium, and sulfur oxides, coal fired boilers by complex sulfates. In both cases, increasing tube metal temperature exacer- bates corrosion rates.

Superheater Corrosion Prevention | Jansen Combustion and

Excessive tube metal wastage in recovery and other waste fuel boiler superheaters due to fireside corrosion has often become troublesome as mills attempt to increase boiler firing capacity. 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.
