  • Heating mantle with a porous radiation wall
    Patent number: 4957431
    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.
