Determination of circulating water outlet temperature
Thread Content
The outlet temperature of the circulating water cooler in general process units is 40 degrees, in order to prevent scaling in the equipment and pipelines of the circulating water system over time. I’m not sure about the scaling situation above 45 degrees
As the outlet temperature increases gradually, it indicates that the heat transfer efficiency is declining; the heat transfer coefficient K becomes smaller. The thermal resistance caused by scaling is significant – for every 0.5 mm of scale buildup, the K value decreases by 20%. Therefore, in such situations, it is necessary to monitor the situation closely. If necessary, the affected section should be removed, a bypass route used, and the system restarted after cleaning.
Thank you, up above!!!!!!!!!!!!!!!!!!!!!!!!!!!:lol
A water quality analysis report can be prepared first, and a judgment can be made based on the ion contents. If scaling is a major concern, online monitoring devices can be installed.
