摘要： A method and apparatus is described for environmentally sound usage of combustible hazardous waste as supplemental fuel in operating rotary cement kilns. The apparatus comprises an open port in the rotary vessel at a point where during cement kiln operation the in-process mineral material is in a calcining state and where kiln gas temperatures are sufficient to decompose volatile components of the waste fuel. A drop tube extending from the port into the kiln is provided to prevent in-process mineral from escaping through the port during rotation of the rotary vessel. Combustible solids are delivered through the port under the force of gravity and air is continuously drawn into the rotary vessel through the open port during kiln operation. The apparatus and method allow efficient usage of combustible solid waste as a supplemental fuel for cement kiln operation.

摘要： Waste tires are disposed of in a cement-manufacturing or other mineral-burning process by introducing the tires into the hot gas stream at at least one point between the mineral-inlet end of a rotary kiln and the lowermost cyclone of an associated preheater system, e.g. into the gas stream within a precalciner vessel or riser duct, the tires being maintained in contact with the hot gas for a sufficient period to effect at least partial combustion of the tires. As an alternative, the tires may be introduced into a Lepol grate preheater.

摘要： A rotary, continuous pyrolytic conversion system converts solid hydrocarbon containing feedstocks into gases, liquid hydrocarbons and char. A converter drum is contained within an outer drum which is in substantially air-tight relationship with an injector for introducing the feedstock in the form of bales and with a discharge chute for the solid products of pyrolysis. A casing around the outer stationary drum defines an oven chamber which is heated by combustion products. A rod extends into the injection end of the converter drum for supporting scrapers against the inner periphery of the converter drum. A crusher bar is carried in the drum at the discharge end thereof and crushes the solid products. A second pyrolysis reactor may receive the solid pyrolysis products and be operative at higher temperature than the first converter to destroy chlorinated hydrocarbons.

摘要： Apparatus for sorting and recovery of scrap material, particularly aluminum beverage can scrap, includes a rotary kiln (10) in which the raw scrap is heat processed to leave a furnace chamber (12) of the kiln as a mix of large particles of a first composition (e.g. larger pieces of soft aluminium alloy can body) and substantially smaller particles of a second and different composition (e.g. aluminium/manganese alloy can top fines). The output end of the kiln is provided with an axially extending screen section (30) to separate the larger particles from the small immediately adjacent to the chamber so that they cn be passed immediately without substantial loss of heat to a melting furnace (38).

摘要： An apparatus is provided for charging containerized fuel, particularly combustible hazardous waste homogenates, through a wall of a rotating kiln with minimal perturbation of mineral processing conditions. During kiln rotation fuel modules are loaded into the apparatus and charged into the kiln through a port in the kiln cylinder wall and onto the contained mineral bed. In a preferred embodiment the apparatus includes a device for actuating a port closure and a drop tube extending from the port into the kiln cylinder and positioned so that in-process mineral material does not contact the port closure during rotation of the kiln cylinder.

摘要： The rotary drum of reactivation apparatus has spaced-apart helical electrodes disposed in mutually interposed helical state and fixed to the inner wall surface of the drum, these electrodes functioning upon rotation of the drum to propel by screw action active carbon from an inlet end to the other outlet end of the drum as electric power is supplied to the electrodes to cause electric discharge therebetween and conduction through the carbon, which is thereby subjected sequentially to drying, firing, and reactivation as a result of electric discharge effect and the resulting joule heat. Flow of excessive current between the electrodes is prevented by a constant-current circuit in the electric power supply system. Steam can be additionally injected against the carbon to promote the reactivation thereof.
