Industrial electrothermics — Introduction

A great deal of progress has recently been made in industrial heating, and heat treatment operations have diversified considerably: metallurgical heat treatments, baking, polymerization, drying, melting, sintering, freeze-drying, distillation...

However, one fundamental fact remains: the growth of industry is closely linked to the availability and choice of a primary energy source.

Beyond the simple considerations of cost and availability that justify the use of electricity, electrothermal energy owes its development to the specific characteristics of this form of energy:

• continuity and constancy of delivered energy characteristics (voltage, frequency) ;

• Ease of use, as electricity can easily be transformed into mechanical, thermal or chemical energy... ;

• easy decentralized, modular use.
