It is an internationally popular electric heating device. Used for heating, insulation, and heating of flowing liquid and gaseous media. When the heating medium passes through the heating chamber of the electric heater under pressure, the huge heat generated during the operation of the electric heating element is uniformly carried away using the principle of fluid thermodynamics, so that the temperature of the heated medium meets the user's process requirements. According to different installation categories, it can be divided into the following: heating tubes, heating plates, heating wires, heating coils, etc. According to material classification: there are cast copper, cast iron, cast aluminum, ceramics, quartz, stainless steel, mica, far-infrared, etc. According to the heating medium, there are air heating, liquid heating, and solid heating.

Method 1: Increase the gas inlet flow rate of the electric heater, which is to enhance convective heat transfer.

Method 2: Modify its external load while keeping other conditions unchanged.
