I would like to ask about the thermal conductivity of iron oxide and ferric tetraoxide
Thread Content
In heat exchanger systems, we encounter rust formation on iron pipes; this rust adheres to the inner walls of the heat exchange tubes, resulting in rust deposits (red rust). This situation reduces the heat exchange efficiency of the iron heat exchange tubes. I would like to know what the thermal conductivity of iron oxide rust deposits is. Also, if it is dense magnetite, could this help improve heat exchange? What is the thermal conductivity of magnetite as well? I would also like to ask about the thermal conductivity of copper oxide/iron hydroxide/silt, etc
They are all very sophisticated questions; to obtain this data, one would need to visit a laboratory. Because the physical structure of these things is difficult to determine.
The form of scale mainly found in the cooling water heat exchange system
Regarding structural issues, it is best to consult a water treatment company; solutions based on handling the problem after it occurs or taking action only after signs appear are not sufficient. The structural process has already been producing under conditions that reduce production efficiency. Efforts should be made in water quality treatment. For reference.
