Typical Damage Prediction and Reliability Analysis of Superheater Tubes in Power Station Boilers Based on Multisource Data Analysis

Energies, 2022
The superheater and re-heater piping components in supercritical thermal power units are prone to creep and fatigue failure fracture after extensive use due to the high pressure and temperature environment.

Conversion of Waste to Sustainable Transport Fuel via Fischer–Tropsch Synthesis: Process Modeling and Life Cycle Analysis

Energy Science &Engineering, Volume 13, Issue 10, Page 4868-4885, October 2025.
ABSTRACT A lifecycle analysis was performed on a process for distributed forest residue collection and conversion into biocrude, followed by biocrude transport to a central facility and indirect liquefaction using Fischer–Tropsch synthesis with refining to sustainable aviation fuel (SAF).

Sustainable Thermal Solutions: Enhancing Heat Transfer with Turbulators and Nanofluids

Advanced Energy and Sustainability Research, Volume 6, Issue 5, May 2025.
Nanofluids, which are nanoparticle suspensions in base fluid, facilitate heat transmission due to their improved thermal conductivity. Turbulators, which are inserts into fluid flow channels, disturb the flow, increasing turbulence and hence the heat transfer rate.

Prediction of NOx Emission Based on Online‐SVR Model Adapts to Ultra‐Supercritical Coal‐Fired Electric Utility Boilers

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
Aiming to address the issue that the performance of the offline model for an ultra‐supercritical coal‐fired power plant boiler gradually degrades after being used for a period under varying operating conditions, this article proposes an online prediction model for NOx concentration based on an adaptive online support vector regression (Online‐SVR ...

Optimal design of reduced vapor transfer dividing wall structures with and without heat integration

AIChE Journal, Volume 70, Issue 11, November 2024.
Abstract A dividing wall column (DWC) is a prime example of process intensification, whereby significant energy and cost savings can be achieved for some systems compared to operation in conventional design of two columns in series. It has been theorized that the vapor and liquid thermal coupling streams in the DWC could be replaced by liquid‐only ...

High-Temperature Graphitization Failure of Primary Superheater Tube

High Temperature Materials and Processes, 2015
Failure of boiler tubes is the main cause of unit outages of the plant, which further affects the reliability, availability and safety of the unit. So failure analysis of boiler tubes is absolutely essential to predict the root cause of the failure and ...

To cascade feedback loops, or not?

Advanced Control for Applications, Volume 6, Issue 3, September 2024.
Abstract Linear time invariant (LTI) block diagrams—and the associated transfer functions—are profoundly inadequate for multi‐loop control system design. A practitioner has to have a thorough understanding of the physical uncertainties—and of their inter‐dependencies—in the different parts of an interconnected system, or in a given block diagram.
