ABSTRACT:
A reactor for direct utilization of external radiation heat includes a containment can having a longitudinal axis, an external driving mechanism for controllable rotating the containment can and a cavity having a cylindrical shape. The cavity is partially lined with an insulation layer and disposed in the containment can. The cavity has a gas inlet, a gas outlet and an aperture for allowing to insert the external radiation heat into the cavity. A feeder mechanism is moveable along the longitudinal axis into and out of the cavity for supplying the material subject to the thermal or thermo-chemical material process. The gas outlet is formed as a ring channel tube having an inner and an outer surface, wherein the feeder mechanism is at least partially hosted within a tube cavity defined by the inner surface. Cooling means are associated with the inner and/or outer surface.
