The way of Energy Saving of Induction heating equipment

The advantages of induction heating equipment, such as fast heating speed, short heating time, energy saving and environmental protection, are used to replace flame furnace and resistance furnace. This is a backward technology and equipment that uses new technology, new equipment to eliminate high energy consumption and pollute the environment. However, the energy saving of   Electric induction heating furnace  should also be reflected in the high thermal efficiency and electrical efficiency of induction heating equipment. Therefore, there are the following ways to save energy and reduce consumption that should be heated.

1. It is important to choose the current frequency correctly, which will directly affect the thermal efficiency of the inductor and the heating efficiency of the blank. For example, when induction heating cylinder blank, blank diameter D and current penetration depth ratio, that is, D/A=2.5~5.5, its heating efficiency is better. When D ≤ A < 2.5, the heating efficiency of blank decreases. When D ≥ A > 5.5, due to the high frequency of the selected current, the heating time is prolonged, the heat loss is increased, the thermal efficiency is reduced, and the heating efficiency is also decreased, and the cost of the frequency conversion equipment is also increased.

2. The increase of the terminal voltage of the inductor is bound to increase the number of turns of the induction coil, thus reducing the current on the induction coil, reducing the power loss of the sensor and improving the electric efficiency of the sensor. At the same time, it also reduces the water consumption of cooling induction coil. It is a good way to save energy by induction heating by increasing the terminal voltage of inductor. the induction heating mode with low voltage and high current should be avoided as far as possible.

3. When the current density of induction coil is fixed, the cross section size of pure copper tube of induction coil should be controlled within a certain range. With the increase of current density, the power loss of induction coil increases and the electric efficiency of inductor decreases. Of course, the cross section size of the pure copper tube of the induction coil is also determined by the number of turns of the induction coil and the geometric size of the inductor.

4. The selected heat-resistant and thermal insulation materials are lined with the heat-resistant layer and the thermal insulation layer in the induction coil, the induction heating equipment selects the material with good insulation performance, and has a certain thickness, which plays a good role in heat insulation and reduces the heat transfer loss of the blank. Improve the thermal efficiency of the inductor.

5. Make full use of the cooling water of the inductor to cool the tap water should be recycled to save water resources. At the same time, the cooled water also has a certain temperature, which can be used for other applications and save heat energy.
