Application of the Energy Approach to the Evaluation of the Serviceability of the Drum of a Steam Boiler Subjected to Thermal Cycling and Hydrogenation

  • Published:
Materials Science Aims and scope

We develop a method for the evaluation of the influence of hydrogen on the strength and durability of the drum of a high-pressure steam boiler subjected to thermal cycling and hydrogenation. We analyze the influence of hydrogen on the accumulation of damage to the metal and the duration of operation of the drum for different modes of damage. It is established that hydrogen accelerates the accumulation of damage and reduces the period of operation of metals by 25–30% for planned shutdowns of the boilers and by 40–50% for their emergency shutdowns.
