  • Failure Analysis and Remedial Solution Suggestion for Superheater Tubes of a Power Plant Boiler …

    2020/5/19 · Superheater tubes are the most critical components of a power plant's boiler. Due to operation in high-temperature and -pressure conditions, platen superheater (primary superheater) tubes in thermal power point boilers are exposed to breakdowns such as creep failure and overheating. Therefore, identifying the causes of these failures and its maintenance is very …

    2018/8/9 · Based on the IMPD approach, we optimized the geometry of the superheater tube of the A-USC boiler as well as its constituent materials. To apply the IMPD to the tube design problem, we developed a creep deformation model based on finite element analysis, a heat transfer model, and two material models constructed via artificial neural networks.

  • Modeling of transient operation of steam superheater in CFB boiler

    The developed model can be used to perform calculations in the full range of boiler load, both during steady and transient boiler operation. Equations describing the physical processes occurring inside the superheater makes the model universal for a given type of a boiler.
