Apparatus for the pyrolysis of material

Apparatus for the pyrolysis of material, which apparatus comprises a pyrolysis chamber, an inlet at a first end of the pyrolysis chamber, an outlet at a second end of the pyrolysis chamber, and feed means for feeding the material through the pyrolysis chamber, the feed means comprising a cranked member in the pyrolysis chamber, at least one elongate member which extends along the pyrolysis chamber between the inlet and the outlet and which has a first end adjacent the inlet and a second end adjacent the outlet, a feed formation connected to the first end of the elongate member such that the feed formation cannot move with respect to the first end of the elongate member, and connector means which connects the second end of the elongate member to the cranked member, and the feed means being such that rotation of the cranked member causes the elongate member and the feed formation to move backwards and forwards with the feed formation moving horizontally in the material from the inlet towards the outlet in order to move the material towards the outlet, and the elongate member and the feed formation moving above the material from the outlet to the inlet.
