AI Technical Summary

Benefits of technology

This patented technology allows for precise measurements of the temperatures within specific areas around a large number of pipes used during industrial processes such as power generation or chemical production. By taking into account these differences between two sides of the process, it becomes possible to calculate more reliable data about how much energy has been transferred through each section of pipeline compared against what was previously calculated based only upon average values from other sections. These technical improvements make this system highly useful tools for prevention measures like shutdowns caused by excessive temperatures outside acceptable limits.

Problems solved by technology

This patented technical solution describes how increasingly larger amounts of energy are being generated from fossil fuel sources like coal or oil over time due to advancements made during this period. These new generation fuels have lower temperatures than older generations with similar levels of efficiency but longer lifetimes compared to previous ones. To address these issues, there needs better ways to monitor the inside walls of the combustion chamber while ensuring they stay within their design limits.
