In this section, we provide an overview of induction heating and delve into its fundamental principles, highlighting its significance in modern industrial applications.

Overview of Induction Heating

Induction heating involves the generation of heat in a conductive material through the electromagnetic field induced by alternating current (AC) passing through an induction coil. Unlike direct flame or conduction-based heating, induction heating does not rely on physical contact between the heat source and the material being heated. Instead, it utilizes the principles of electromagnetic induction to induce eddy currents within the material, resulting in efficient and localized heating.

The key components of an induction heating system include a power supply, an induction coil, and the workpiece to be heated. The power supply delivers high-frequency AC power to the induction coil, which generates a varying magnetic field. This changing magnetic field induces eddy currents within the conductive workpiece, which, in turn, results in resistive heating due to the Joule effect.

Fundamental Principles of Induction Heating

The fundamental principles underlying induction heating can be summarized as follows:

Electromagnetic Induction

Induction heating relies on Faraday’s law of electromagnetic induction, which states that a changing magnetic field induces an electromotive force (EMF) in a closed loop. In the case of induction heating, the alternating current flowing through the induction coil generates a varying magnetic field that penetrates the workpiece, inducing eddy currents.

Skin Effect

The skin effect is a phenomenon observed in induction heating, wherein the eddy currents tend to concentrate near the surface of the conductive material. This effect is due to the self-induced magnetic field opposing the changes in the magnetic field produced by the induction coil. Consequently, the heat generation is predominantly concentrated near the surface, enabling rapid and efficient heating.

Magnetic Hysteresis

Magnetic hysteresis refers to the characteristic behavior of ferromagnetic materials to retain a portion of the magnetic field even after the excitation has ceased. This phenomenon is exploited in induction heating applications that involve the heating of ferromagnetic materials, allowing for precise control over the heating process.

Induction Superheated Steam for Crop Treatment

Induction steam treating of crops is a process of applying hot steam to the soil or substrate to reduce the incidence of soil-borne diseases, weeds, and insect pests. Induction steam treating uses an electrically powered boiler to generate steam, which is then injected into the soil through perforated pipes or hoses. The steam heats up the soil to temperatures that kill or inactivate harmful organisms, such as fungi, bacteria, nematodes, viruses, and weed seeds². Induction steam treating can also disinfect compost, potting soil, pots, tools, and other equipment¹.

One of the advantages of induction steam treating of crops is that it can provide rapid and uniform heating of the soil or substrate, without the need for external combustion or heat transfer. Induction steam treating can also enable good mixing and temperature control of the soil or substrate, which can improve the quality and yield of crops³. Induction steam treating can also reduce the energy consumption and emissions of the process, as it converts up to 80% of the expended energy into useful heat and produces no smoke, pollution, waste heat, or noise¹.

Induction steam treating of crops can be applied to various types of soils and substrates, such as peat, sand, clay, loam, and organic matter. The steam treatment can be done in greenhouses, high tunnels, open fields, or containers. The steam treatment can be done in a band or strip fashion to target specific areas or crops, or in a broadcast fashion to treat larger areas or multiple crops. The steam treatment can be done before planting or transplanting to prepare the soil or substrate, or after planting or transplanting to control emerging weeds and pests²³.

Induction steam treating of crops is a promising technology that can provide a sustainable way of managing soil-borne diseases, weeds, and insect pests in agriculture. Steam treatment can improve crop productivity and quality, mitigate climate change by reducing greenhouse gas emissions and chemical inputs, and reduce the dependence on fossil fuels and fumigants.
