The power calculation of electric heating tube is mainly analyzed from two aspects:
1. If the heating tube has been done, we only need to measure the resistance value of the electric heating tube, and then combine the rated voltage of the electric heating tube to calculate the power, the formula is: power = voltage * voltage / resistance.
2. How much power is required for water tank heating? Or how much power of electric heating tubes is needed in a dry-firing oven? If these problems are problems, they are power design problems.
Regarding the power design, it is necessary to design it in combination with specific operating condition information:
The design of water tank power, we need to know: water volume (kg), temperature difference, heating time, whether there is a thermal insulation layer, whether it is closed heating, etc., after knowing these parameters, we can roughly estimate how much power.
The design of oven power, we need to know: the size of the oven space (cubic meters), temperature difference, heating time, whether there is thermal insulation layer, whether closed heating, etc., after knowing these parameters, we can roughly estimate how much power.
