Finding the Root Cause of Boiler Tube Failures

Tube OD surfaces experience thermal fatigue stress cycles which can occur from normal shedding of slag, sootblowing, or from cyclic operation of the boiler. Thermal cycling, in addition to subjecting the material to cyclic stress, can initiate cracking of the less elastic external tube scales and expose the tube base material to repeated corrosion.

Boiler Combustion | CleanBoiler.org

Carbon black is produced by the reaction of a hydrocarbon fuel such as oil or gas with a limitedsupply of combustion air at temperatures of 1320 to 1540°C (2400 to 2800°F). The unburned carbon iscollected as an extremely fine black fluffy particle, 10 to 500 nanometers (nm) in diameter. The principaluses of carbon black are as a reinforcing agent in rubber compounds (especially tires) and as a blackpigment …
