摘要： A kiln comprising a substantially cylindrical drum (11) supported from a support structure for rotation about its central axis whereby the drum is supported such that the central axis is generally horizontal and whereby the drum is configured and/or arranged such that rotation of the drum will cause fluid particulate material to flow from one end (13) to other end (15). The one end being associated with a fuel inlet (33) and the other end being provided with a discharge (37) for combustion products and heat. The inner face of the side wall of the drum is provided with a plurality of ports (29) which are located at spaced intervals along and around the interior of the drum and which open into the interior of the drum, the one end being closed by an end assembly (23) fixed relative to the support structure whereby the one end is in close abutting relationship with the end assembly. An opening (25) is provided in the end assembly, the opening connected to a source of air (31). A set of passageways (27) are provided at angularly displaced positions around the kiln, said passageways communicating with the ports, the inlets of passageways opening into the face defining the one end, the opening being positioned such that on rotation of the drum the inlets of the passageways rotate past the opening.

摘要： A mercury retorting apparatus, a retorting system, and a method for continuous removal of mercury from dry, semi-granular, and sludge materials contaminated with mercury without shutting down the system for removal of accumulated liquid mercury, water, and dust particles. The retorting apparatus comprises a powered screw feed assembly having a feed tube with a closely fitting feed screw therein. The screw feed assembly feeds the material from the lower portion of a hopper configured to contain a quantity thereof into a rotatably powered retorting tube in which a vacuum is drawn. The material forms a seal within the powered screw feed assembly against vacuum loss in the retorting tube during operation thereof. A first rotatable seal between the feed tube and retorting tube prevents vacuum loss therebetween. An elongate electric kiln encloses the mid-portion of the retorting tube. An output hopper for receiving retorted material from the retorting tube is connected to the opposite end thereof by means of a second rotary seal. An outlet pipe assembly extends downwardly from the outlet hopper having an outlet pipe with a valved airlock to allow retorted material to pass therethrough. An off gas outlet pipe extends from the output hopper for removing off gasses containing mercury vapor for collection. The mercury retorting system comprises the mercury retorting apparatus, a pair of valved mercury recovery systems connected in parallel to the retorting apparatus for condensing the mercury vapor from the offgasses, and a vacuum pump connected to the mercury recovery systems.
