The basic method of calculation by the electric heater power

We all know that customers in consulting products, we often ask us how long the number of degrees to how many degrees do much power today, we will explain as we look at the heater power calculation.

??? First, the calculation of heating power to pay attention to the following three aspects:

Heat loss in a power start running when the power system

??? Second, consider the following worst-case calculation:

A minimum ambient temperature

(2) the shortest running cycle

Highest operating temperature

The maximum weight of the heating medium (mobile media compared to the maximum flow rate)

??? Third, the electric heater power design steps:

(1) according to the process, the draw of the heating process flow diagram (not involved in material form and specifications).

(2) calculation of the process heat required.

Computing systems start the required heat and time.

??? Fourth, consider the appropriate safety factor to determine the total power of the heater.

(1) determine the heating element sheath material and the power density.

(2) to determine the heater in the form of the size and number.

(3) determine the heater power and control systems.
