Why does carbon deposit form on the surface of ceramic heating rods used for heat transfer oil?

       There is a reason for carbon deposition on alumina ceramic heating rods for heat transfer oil. Why does carbon deposit form on the surface of heat transfer oil heating rods? The reason is that the heat transfer oil will carbonize if the temperature is too high. When the heating tube is working, the surface temperature is very high, causing local overheating and forming carbon deposits.

 

Solution:

1. Choose a better quality heat transfer oil;

2. Reduce the surface load of the heat transfer oil heating rod;

3. Choose a pump with a higher flow rate as much as possible. A faster flow rate can reduce the possibility of local overheating of the heat transfer oil;

4. When the heat transfer oil ceramic heater stops working, the temperature should be lowered to room temperature first to avoid stopping at high temperature. Because at the moment of stopping during high-temperature operation, the surface of the heating tube is still at a high temperature. At this time, the heat transfer oil around the heating tube stops flowing, causing local overheating of the heat transfer oil on the surface of the heating tube and forming carbon deposits.
