The advantages of electric heating tubes in the heating field

 

The electric heating tube has the characteristics of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, simple installation and long service life. Because electric heating tubes are cheap, easy to use, and pollution-free, they are widely used in various heating occasions, such as saltpeter tanks, water tanks, oil tanks, acid and alkali tanks, fusible metal melting furnaces, air heating furnaces, drying furnaces, drying boxes, heat Press molds, etc. Let's take a look at the advantages of electric heating tubes in the field of heating.

(1) Moderate one-time investment and low maintenance cost.

(2) Electric heating is clean and hygienic, free of soot, oil, and environmental pollution.

(3) The thermal inertia is small, the temperature control precision is high, and the heating effect is good.

(4) The electric heating power is convenient to adjust, easy to adjust the temperature, and realize automatic control.

(5) The electric heating method may generate a large amount of heat energy in a small range, so it can be heated at a high speed to reach a predetermined temperature.

(6) There is no need for ambient atmosphere, unlike burning fuel which needs to rely on oxygen, so the heated objects are not easy to oxidize.

(7) High thermal efficiency. Compared with other energy sources, the thermal efficiency of coal is about 12%-20%, liquid fuel is about 20%-40%, gas fuel is about 50%-60%, steam is about 45%-60%, and electricity is about 50%. %-95%.

(8) The object to be heated can be easily moved mechanically and automatically in the heating zone, which creates extremely favorable conditions for the application of electric heating in production lines and automated production lines.
