The heater itself and magnetic yoke are kept at room temperature

The working principle is to install a primary coil with more turns and a secondary coil with fewer turns on the same iron core. The voltage ratio between input and output is equal to the ratio of coil turns, while the energy remains constant. Therefore, the secondary coil generates a large current under low voltage conditions.

For an induction heater, the bearing is a short circuited single turn secondary coil that generates a large amount of heat through a large current under lower AC voltage conditions. The heater itself and magnetic yoke are kept at room temperature. Due to the induction of current by this heating method, the bearing will be magnetized. It is important to ensure that the bearings are demagnetized in the future so that they do not attract metal magnetic debris during operation. FAG induction heaters all have automatic demagnetization function.

It is the use of metal to generate eddy currents in an alternating magnetic field to generate heat, usually used in metal heat treatment and other aspects. The principle is that when thicker metals are exposed to an alternating magnetic field, an electric current is generated due to electromagnetic induction. After thicker metals generate current, the current will form a spiral flow path inside the metal, so that the heat generated by the current flow is absorbed by the metal itself, which will cause the metal to quickly heat up.

This device is an energy-saving device that pre heats or re heats fuel oil. It is installed before the combustion equipment to achieve heating of the fuel oil before combustion, reducing its viscosity at high temperatures (105 ℃ -150 ℃), promoting full atomization combustion, and ultimately achieving the goal of energy conservation. It is widely used in the pre heating or secondary heating of fuel oils such as heavy oil, asphalt, and clear oil.
