What we can do if the thermal oil heating tube is easy to form carbon-laydown?

The heating pipe for heating water is liable to form scale, and the thermal oil heating tube is easy to form carbon-laydown. Earlier, I analyzed the "effect of scale on the heating tube" with you. Today we will talk to you about the reasons why the thermal oil heating tube is easy to form carbon-laydown and how to prevent the thermal oil heating tube from forming carbon-laydown.

 

The thermal oil heating tube is easy to form carbon-laydown. The reasoning goes like this: the temperature of the thermal oil is too high, so it will be easy to carbonize. The temperature of the surface of the heating tube is very high. If the flow rate of the thermal oil in the heating tube is too low, it will cause the local temperature of the thermal oil on the surface of the heating tube to be too high, forming carbon deposits.

 

What kind of measures can we take to prevent such a carbon formation problem?

 

1. First of all, considering the heating tube itself, we generally recommend that the surface load of the customer should not be too high (the heating tube power per meter is best controlled within 1.5-2KW/m), so as to reduce the surface temperature of the heating tube.

 

2. Secondly, the material of the electric heating tube can be medium carbon steel, high carbon steel, stainless steel or the scale coating treatment heating tube of our Yancheng Laiyuan Electric Equipment Co., Ltd.. This electric heating tube not only plays a very important role in waterproof scale The big effect will also play a role in the problem of carbon formation.

 

3. Choose thermal oil with better quality.

 

4. The flow rate of the pump in the heat transfer oil furnace should be as large as possible. The flow rate is fast, which can reduce the possibility that the temperature of the heat transfer oil is too high.

 

5. When the heat conduction oil heater stops working, the temperature should be reduced to normal temperature first to avoid high temperature shutdown. Because the surface of the heating tube is still in a high temperature state at the moment of shutdown at a high-temperature operating state, at this time, the heat transfer oil in the heating tube barrel stops flowing, which will cause the local temperature of the heat transfer oil on the surface of the heating tube to be too high, forming carbon deposits.

 

All in all, the purpose of all our measures is the same, as far as possible to reduce the surface temperature of the heating tube, if the temperature is lowered, it is not easy to form carbon-laydown.
