A pyrolysis apparatus is constructed of a first sheet 26b of high thermal conductivity metal affixed to a second sheet 26a of a high temperature strength metal. The high thermal conductivity metal may be copper and the high temperature strength metal may be stainless steel or a nickel alloy. The metals may be joined together by explosive welding. The apparatus may be a cylindrical, rotatable retort or two co-rotating inner (29, Fig. 3) and outer (26, Fig. 3) bodies. The inner body (29, Fig. 3) may have holes to allow particulate material through and the both inner and outer bodies may have vanes (31, Fig. 12) to retain particulate material. The retort may be driven by a reversible drive (20, 35, Fig. 3) and its inclination varied by a hydraulic arrangement. Portions of the second sheet 26a may be milled away to form a framework leaving parts of the first sheet 26b exposed. The apparatus may be enclosed in a thermally insulated housing (40, Fig. 7) and may have a heating system (15, 17, Fig. 7) for performing pyrolysis of a calorific material. |
