Method for installing electrically operated heating element in e.g. porous medium, involves performing thermal conduction of medium such that heat transfer from element to medium takes place due to conduction, convection and radiant heat

摘要

The method involves pressing, hitting or installing a heating element into a naturally existing or artificially produced cavity, where the cavity is filled with a heat conducting material such that failure of the heating element is prevented by a control system. Thermal conduction of the porous medium is performed by the control system during a heating process such that heat transfer from the heating element to the porous medium to be heated takes place due to conduction, convection and radiant heat.
