Why is electromagnetic induction heating more energy-efficient than traditional heating methods?

For the heating industry, electromagnetic induction heating is the most energy-efficient. Compared with traditional heating methods, what are its characteristics and advantages? Let’s compare them in detail below.

Conserving energy, improving energy efficiency, protecting and improving the environment, and promoting comprehensive, coordinated and sustainable economic and social development are my country’s current strategic tasks.

For the heating industry, there are many heating methods. The most energy-saving is electromagnetic heating. The principle of electromagnetic heating is derived from the electromagnetic induction phenomenon discovered by Faraday, that is, alternating current induces current in the conductor, which causes the conductor to heat up. Let’s analyze in detail the reasons why electromagnetic heating is more energy-saving than other heating methods.

In the traditional heating industry, most of the heating methods use resistance wire, and this traditional heating method is generally not high in thermal efficiency. After the resistance wire is energized, it heats itself and then transfers the heat to the medium, thereby heating the object. The effect is that the maximum heat utilization rate of this heating effect is only about 50%, and the other 50% is part of the heat loss, and part of it is converted into other energy.

Electromagnetic induction heating uses electric current to generate a magnetic field to make the metal pipe heat itself. In addition, Linding’s patented water-immersed furnace body prevents heat from the pipe and avoids the loss of heat. The thermal efficiency is as high as 97%. The electrical effect can reach 50%, but considering the electromagnetic induction heating controllers of different brands and different qualities, the energy conversion efficiency will be slightly different.

The advantages of electromagnetic induction heating mainly have the following three points:

1. The electromagnetic heating speed is fast, which can double the productivity of heating equipment, and can form a continuous production line with other process equipment.

2. The electromagnetic heating time is short and the efficiency is high, which not only saves energy but also saves time.

3. Low electromagnetic heating loss. This feature virtually solves the heat dissipation problem of the equipment, greatly reduces the temperature of the household or workshop, improves the living and working conditions, and purifies the surrounding environment.

Through comparison, we can see that electromagnetic induction heating is superior to traditional heating methods in all aspects, and because people’s awareness of energy conservation and emission reduction has gradually improved, more and more energy-saving and environmentally-friendly new processes and new equipment have been adopted in reality. , New technology, eliminate backward products.
