ARTICLE 665. INDUCTION AND DIELECTRIC HEATING EQUIPMENT665.1. Scope. Induction and dielectric heating are systems, wherein a work-piece is heated by means of a rapidly alternating magnetic or electric field.665.2. DefinitionsDielectric heating In contrast, dielectric heating is used to heat materials that are nonconductors, such as wood, plastic, textiles, and rubber, for such purposes as drying, gluing, curing, and baking. It uses frequencies from 1 to 200 MHz, especially those from 1 to 50 MHz. Vacuum-tube generators are used exclusively to supply dielectric heating power, with outputs ranging from …
