The relationship between immersion heaters in oil storage tanks and temperature drop in circulating oil?
Whether in daily life or in industrial use, heating oil is a common phenomenon, and immersion heaters are generally used for heating. When heating the circulating oil, there is a temperature drop between the surface temperature of the immersion heaters and the oil being heated. So the relationship between the temperature of immersion heaters and the temperature drop in circulating oil?
The following lists the relationship between temperature and temperature drop in circulating oil (when the surface load of the heating tube is 2.8W/cm2).
1. When the surface temperature of immersion heaters is 150 degrees and the oil temperature is 15 degrees, its temperature drop is 135 degrees.
2. When the surface temperature is 147 degrees and the oil temperature is 40 degrees, its temperature drop is 107 degrees.
3. When the surface temperature is 142 degrees and the oil temperature is 75 degrees, its temperature drop is 66 degrees.
4. When the surface temperature is 142 degrees and the oil temperature is 90 degrees, its temperature drop is 52 degrees.
5. When the surface temperature is 144 degrees and the oil temperature is 100 degrees, its temperature drop is 44 degrees.
It can be seen from the above data that the temperature in the circulating oil has a close relationship with the temperature drop: the closer the oil temperature is to the surface temperature of the immersion heaters, the smaller the temperature drop. When the surface temperature of the immersion heaters of the heating oil does not change, The lower the temperature drop, the higher the oil temperature. Of course, this is the data tested in the same viscosity oil.
In fact, the size of the temperature drop mainly depends on the viscosity of the oil, and the viscosity of the oil determines its temperature. The lower the temperature, the higher the viscosity of the oil, so that the fluidity of the oil is poor, and if the fluidity is poor, the speed of absorbing the surface temperature of the electric heating tube will be slow. The temperature drop will be greater.
Therefore, when a customer customizes Immersion Heaters in Oil Storage Tanks, we always ask the customer what the viscosity and fluidity of the oil he wants to heat. Then use the relationship between temperature and temperature drop in circulating oil as a reference to design immersion heaters with reasonable surface load for customers.
