[0002] The boiler steam-water corrosion online monitoring device is a technology used to monitor the corrosion phenomena caused by water, steam and their interaction in the boiler system in real time. By installing sensors and monitoring equipment at key locations of the boiler, the chemical composition and environmental parameters (such as temperature, pressure and humidity) in the water vapor are continuously collected and analyzed. Early signs of corrosion can be detected in a timely manner, processed through advanced algorithms, potential corrosion risks can be identified, and early warnings and optimization suggestions can be provided to operators to prevent equipment damage and production interruptions.

[0003] When in use, traditional boiler monitoring devices monitor key parameters in real time through multiple sensors installed in the boiler system.
