The electric heating pipe has the characteristics of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, simple installation and long service life. Because the electric heating tube is cheap, easy to use and non-polluting, it is widely used in various heating occasions, such as saltpeter tanks, water tanks, oil tanks, acid-base tanks, fusible metal melting furnaces, air heating furnaces, drying furnaces, drying boxes, heat Press mold, etc. Let's take a look at the advantages of electric heating tubes in the field of heating.
(1) The one-time investment is moderate and the maintenance cost is small.
(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) No ambient atmosphere is required, unlike burning fuel which needs to rely on oxygen, so the heated object is not easily oxidized.
(7) High thermal efficiency. Compared with other energy sources, the thermal efficiency of coal is about 12 percent -20 percent , liquid fuel is about 20 percent -40 percent , gas fuel is about 50 percent -60 percent , steam is about 45 percent -60 percent , and electric energy is about 50 percent . percent -95 percent .
(8) The heated object can be easily moved mechanically and automatically in the heating area, which creates extremely favorable conditions for the application of electric heating in production lines and automated production lines.
The above is an introduction to the advantages of electric heating tubes in the field of heating. I hope everyone can understand.
