Description

Technical Field

[0001] The utility model relates to a temperature data acquisition device, in particular to a water-cooled wall temperature data acquisition device. Background Art

[0002] In the study of water-cooled wall temperature deviation detection, it is very important to detect each row of water-cooled wall tubes. When the temperature of the adjacent measuring points of the water-cooled wall deviates, or the local temperature is too high, it means that the water-cooled wall may be partially blocked or the water-cooled wall pipes may be deformed. During the combustion process, the performance of metal materials changes with the passage of time. Therefore, online monitoring of the wall temperature is particularly important. However, it is not realistic to install measuring points on the wall facing the fire side for monitoring. Therefore, measuring points are installed at appropriate tube wall positions to obtain the temperature of the desired point through monitoring, and the relevant information is promptly fed back to the operator so that appropriate adjustments can be made.

[0003] However, the water wall temperature detection device in the prior art cannot collect the wall temperature at different locations of the water wall, which leads to deviations in the detection results and is not conducive to obtaining real-time wall temperature information. In view of this, the present application designs a water wall temperature data acquisition device. Utility Model Content
