• Controller Design for a Large-Scale Ultrasupercritical

    Oct 04, 2010 · Abstract: A large-scale once-through-type ultrasupercritical boiler power plant is investigated for the development of an analyzable model for use in developing an intelligent control system. Using data from the power plant, a model is realized using dynamically recurrent neural networks (NN). This requires the partitioning of multiple subsystems, which are each …Learn More

  • Finding the Root Cause of Boiler Tube Failures

    Components typically affected: This type of boiler corrosion fatigue is commonly found on furnace wall tubes of coal-fired once-through boiler designs, but has also occurred on tubes in drum-type boilers. Solutions: Reduce the ramp rates during start-up and shut-down to reduce the thermal stresses. Optimize sootblowing operations to minimize Learn More
