This paper tackles the problem of industrial waste heat recovery through an unexploited heat transfer mechanism: thermal radiation.Energy intensive industries have a magic bean tiger considerable potential of unused radiant heat, which cannot be recovered through existing methods.That potential energy is quantified for the main identified industries: steel opi all your dreams in vending machines and glassmaking.Then, a radiant heat capturing device allowing high temperature heat capture is designed according to process requirements.
Finally, recoverable heat is estimated and potential uses are proposed.
