How To Know The Surface Temperature Of Dry Fried Heater Elements?

The surface temperature of the electric heating element is the heat generated by the heating wire passing through the magnesium oxide powder filled in the heating tube, which penetrates into the tube body. At this time, the surface of the heating tube has a temperature. How to know the surface temperature of the electric heating tube?

The surface temperature of the electric heating tube is determined by the surface load of the electric heating tube, and the surface load is determined by the surface area and power of the electric heater element.

First of all, we need to know what is the surface load of the electric heating tube. The surface load refers to the power shared by the unit area on the surface of the electric heating element, expressed in w / cm2.

• Still Air

1. When the surface load reaches 1W / cm2, the surface temperature of the heating tube can reach 300 ℃;
2. When the surface load reaches 2W / cm2, the surface temperature of the heating tube can reach 420 ℃;
3. When the surface load reaches 3W / cm2, the surface temperature of the heating tube can reach 500 ℃;
4. When the surface load reaches 4W / cm2, the surface temperature of the heating tube can reach 580 ℃;
5. When the surface load reaches 5W / cm2, the surface temperature of the heating tube can reach 630 ℃;
6. When the surface load reaches 6W / cm2, the surface temperature of the heating tube can reach 680 ℃;
