AI Technical Summary

Technical Problem

During the peak shaving process of thermal power unit, the expansion of the boiler water-cooled wall deviates from the original design state, resulting in disharmonious deformation and increasing safety risks. The existing technology cannot monitor and evaluate the expansion state in real time.

Method used

Multiple groups of measurement points are arranged on the water-cooled wall. By measuring the real-time thermal expansion, the degree of deformation dissonance at the same elevation is calculated, and the expansion state is evaluated in real time.

Benefits of technology

Real-time monitoring and evaluation of the expansion state of the boiler water-cooled wall is realized, and the degree of deformation dissonance can be identified in a timely manner and safety risks can be reduced.
