Electromagnetic Heating Mainframe

The core working principle of the electromagnetic heating mainframe is electromagnetic induction eddy current heating principle. Based on Faraday's law of electromagnetic induction, the equipment converts power frequency AC into DC through a rectifier filter circuit, then converts the DC into 20-40KHz high-frequency alternating current through the IGBT inverter module. When the high-frequency current flows through the induction coil, it generates a high-speed alternating magnetic field. When the magnetic lines of force in the magnetic field pass through the magnetically conductive metal (boiler body, heating cylinder), countless small eddy currents will be generated in the metal body, making the metal cylinder heat itself at high speed, so as to realize efficient heating of the medium (water, heat transfer oil, etc.) in the boiler. This technology complies with the national standard General Technical Conditions for Electromagnetic Induction Heating Devices GB/T 38751-2020, and also meets the mandatory specifications of Boiler Safety Technical Code TSG 11-2020 issued by the State Administration for Market Regulation of China, and fully conforms to the technical standards for industrial electric heating equipment issued by the Institute of Electrical and Electronics Engineers (IEEE). It is the core energy-saving technology replacing traditional coal-fired and resistance heating in the field of clean heating and industrial heating at present, with thermal efficiency far exceeding traditional heating methods.

3. Core Structure and Working Process of AIX Boiler Electromagnetic Heating Mainframe

AIX boiler electromagnetic heating mainframe adopts modular integrated design, with exclusive high temperature resistance, anti-interference and long life optimization for boiler operation scenarios. The core structure includes six core units: rectifier filter module, IGBT inverter module, intelligent variable frequency control module, resonant induction unit, multiple safety protection module, and human-computer interaction unit. Each unit adopts industrial-grade original genuine accessories. The operation stability, heating efficiency and service life of the equipment are far higher than the industry average level. The core working process is divided into four core stages:

1. Rectification and Filtering Stage

Power frequency AC enters the equipment through the input protection circuit, and is processed by the rectifier bridge stack and filter capacitor circuit to convert the 50Hz power frequency AC into smooth DC, eliminating the impact of power grid fluctuation on the equipment, providing stable DC power for the rear inverter module. At the same time, it has built-in surge protection and overvoltage protection circuits to ensure the stable operation of the equipment in complex power grid environments.

2. High Frequency Inversion Stage

The smooth DC is transmitted to the IGBT high-frequency inverter module, driven accurately by the intelligent variable frequency control system, converting the DC into 20-40KHz high-frequency alternating current. The exclusive variable frequency algorithm of AIX can automatically adjust the inverter frequency and output power according to the furnace body temperature, medium pressure and set parameters to achieve precise temperature control. Compared with traditional fixed frequency equipment, it can further reduce energy consumption by 10%-15%.

3. Induction Heating Stage

The high-frequency alternating current is transmitted to the resonant induction coil, generating a high-speed alternating magnetic field around the coil. The magnetic lines of force penetrate the insulation layer and act on the magnetically conductive metal furnace body of the boiler, generating dense eddy current effect inside the furnace body metal, making the furnace body heat up quickly and evenly by itself, directly heating the water, steam, heat transfer oil and other media in the furnace body without intermediate heat conduction link, greatly reducing heat loss, and the maximum thermal efficiency can reach 99%.

4. Intelligent Control and Protection Stage

During the operation of the equipment, the intelligent control system collects the equipment operation data and boiler working condition data in real time through temperature sensors, pressure sensors, current and voltage sensors, automatically adjusts the output power, accurately controls the medium temperature and pressure. At the same time, it has more than 30 heavy safety protection mechanisms such as overvoltage, undervoltage, overcurrent, overheating, water shortage, phase loss, leakage protection. Once an abnormality occurs, it will immediately trigger protection and alarm, fully ensuring the safe operation of the equipment and boiler system, and can realize 24-hour unattended continuous operation.
