Abstract
A heating mantle for heating materials in a retort includes a housing for a chamber holding the retort, a source of hot gases and a porous wall. The gases pass through the porous will which heats the retort. The heating takes place in a so-called porous wall radiation barrier process. In the first step, the gases passing through the wall heating it be convection. In the second stage, the heated porous wall radiates heat towards said retort.
