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 ...

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.

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 ...
