<p>Liquid media, particularly spent oil, are heated by means of a radiating energy, particularly infrared radiation. An infrared radiation source (5) is arranged to this effect in a container (1). Insulating tubes (4) prevent a heat transfer by convection or conduction to the medium. This enables to carry out the cracking of the spent oil without formation of undesirable deposits on the tubes of the infrared radiation source. </p> |
