capacitors with conventional all-film dielectric designs and also with Gemvar metallized polypropylene designs. We are an industry proven quality leader and supplier to major original equipment manufacturers worldwide. GE is a global supplier of water cooled and air cooled capacitors to the Induction Heating and Melting Industry forFile Size: 2MB. The paper presents a survey of the industrial applications of electric heating from an electrical engineering view-point. The different electrical heating processes possible are described including direct and indirect resistance, induction and dielectric heating plasma, laser- and electron-beam processes for such processes as heat treatment, drying, melting metals and plastics, chemical Cited by: 2.

Simply stated, induction heating is the most clean, efficient, cost-effective, precise, and repeatable method of material heating available to the industry, today. Induction heating takes place in an electrically conducting object (not necessarily magnetic steel) . Induction heating definition: the heating of a conducting material as a result of the electric currents induced in it | Meaning, pronunciation, translations and examples.

Dielectric heating is also known as radiofrequency heating or electronic heating. When a non-metallic material such as wood, plastic, bone, or ceramic is subjected to an alternating electrostatic field, the dielectric loss occurs in it.

This loss appears in the form of heat in dielectric heating. It is the basic dielectric heating principle. Here the term dielectric heating is used to represent the radiofrequency (RF) and microwave (MW) bands of the electromagnetic spectrum. RF heating is in the frequency range 1– MHz and MW from MHz to GHz.

By international agreement, certain frequencies have been allocated for industrial use, in order to avoid interference with telecommunications. The definition of dielectric heating can be stated as – ‘the process of heating up material by causing dielectric motion in its molecules using alternating electric fields“.

All materials are made up of molecules that are composed of atoms. The Dielectric Heating circuit diagram is shown below. Induction heating is the process of heating an electrically conducting object (usually a metal) by electromagnetic induction, where eddy currents (also called Foucault currents) are generated within the metal and resistance leads to Joule heating of the metal.

Induction heating is a form of non-contact heating. The frequency spectrum most commonly used for dielectric heating is in the range of 3 MHz to 30 GHz, corresponding to a wavelength of m to 1 cm.

The heating effect of high frequencies is based on the interaction of the electric and magnetic field, generated by the high frequency, with the insulating Size: KB. Shop for Books on Google Play. Browse the world's largest eBookstore and start reading today on the web, tablet, phone, or ereader.

Dielectric heating, also called Capacitance Heating, method by which the temperature of an electrically nonconducting (insulating) material can be raised by subjecting the material to a high-frequency electromagnetic method is widely employed industrially for heating thermosetting glues, for drying lumber and other fibrous materials, for preheating plastics before molding, and for.

Additional Physical Format: Online version: Induction and dielectric heating. London: British Electrical Development Association, [?] (OCoLC) Abstract: Induction and dielectric heating have assumed in recent years an important position in industrial heating; dielectric heating more recently than induction.

These unique forms of heating, once responsible only for power losses in electric equipment and machinery, offer many advantages over conventional means of heating by convection, conduction, and radiation. The induction and the microwave are physical phenomena that allow targeted heating of an applicable item for use in many fi elds of industry.

It uses high frequency electricity - to heat materials that are electrically conductive. Since it is non-contact, the heating process does not contaminate the food material being heated.

There will always be a temperature gradient, but this can be minimized by careful selection of induction heating parameters. Neglecting the temperature gradient, the absorbed power /5(2).An induction furnace is an electrical furnace in which the heat is applied by induction heating of metal.

Induction furnace capacities range from less than one kilogram to one hundred tonnes, and are used to melt iron and steel, copper, aluminium, and precious metals.
