AI Technical Summary

Technical Problem

In existing technologies, temperature-measuring optical fibers are easily damaged in the harsh working conditions inside the boiler furnace, resulting in poor timeliness and accuracy of temperature measurement, which affects the normal operation of the boiler.

Method used

A special fiber optic protection device for boilers was designed, including a protective block, a connecting column, and a welded protective sleeve. By attaching to the water-cooled wall tube and fixing it to the fins, a measuring groove and fiber optic channel are formed to protect the temperature measuring fiber and avoid scouring by gas-solid two-phase flow and impact by solid ash.

Benefits of technology

This improved the safety, timeliness, and accuracy of temperature measurement via optical fiber, ensuring the normal operation of the boiler.
