This technical paper provides a review of the state of electric industrial process heatingtechnologies and discusses new heating applications for industrial processes. The informationpresented in this paper is based in great part on the 2010 EPRI technical update titled “IndustrialProcess Heating: Current and Emerging Applications of Electrotechnologies”. Four efficientelectric process-heating technologies are discussed, namely, induction heating, microwaveheating, radio frequency heating, and infrared heating. An overview of industrial process heating,principles of operation and the industries where the process heating technology is applied arediscussed. The technical paper also presents current and emerging applications of electricprocess heating technologies. The information presented will help readers answer questionsregarding industrial process heating and provide information on new and efficient heatingapplications. The technology presented can serve as a reference guide for selecting processheating technologies in industrial applications.
