摘要： A method and apparatus is disclosed for indirectly drying and preheating fine material, in particular, moisture containing coal or the like, comprises, providing a rotary drum which is mounted for rotation and has a plurality of heating tubes extending therethrough, supplying heated cooling gas from a dry coke cooling system to the heating tubes, supplying the moist material to the drum, adjacent the bottom thereof, removing the material from the drum after it has been predried and preheated, and returning or recycling a portion of the predried and preheated material to the rotary drum. The method and apparatus utilizes the heated cooling gas used to cool dry coke in a dry coke cooling plant from high temperatures to below 200.degree. C. It has been found that such heated cooling gas for a selected amount of dry coke is useful either in a series of more than one rotary drum or, to process moist material in a single rotary drum and also generate steam as a byproduct.

摘要： A method of producing abrasion resistant coke from brown coal briquets in a shaft furnace comprises charging the coke briquets into the top of the furnace and removing coke from the bottom of the furnace while directing inert hot combustion gases into the furnace and through the briquets at a plurality of vertically spaced levels throughout the height of the shaft furnace. Gases are directed at temperatures to effect and successively lower stages of the furnace the preheating, predrying, carbonization, and cooling of the charge. In accordance with a feature of the invention, gases are collected in each of the preheating and predrying stages by the use of a tubular suction arm which extends substantially across the width of the furnace and includes a performated bottom and sidewalls which extend partly below the bottom and are provided with a saw-tooth configuration so as to withdraw the gases through the space below the bottom and through the perforations of the bottom and to effect entrainment of dust from the charge in so doing. The shaft furnace construction for carrying out the method includes means for circulating the hot gases into each of the stages and the closed tubular suction arm which extends substantially across the whole width of the furnace in each of the preheating and predrying stages includes a bottom perforated wall and side walls which extend downwardly beyond the bottom and arranged so as to draw off a percentage of the gases from the associated stage and in so doing prevent the outflow dust along with the gases. The construction is such that about 10% of the gases is evacuated below the perforated bottom and then up through the bottom and withdrawn through the suction arm.

摘要： The coke forms are produced in four stages, each constituted by a respective oven chamber, and in which the briquets are, respectively, preheated, dehydrated or dried, carbonized and cooled. Hot gas circuits are provided, in which the hot gas is composed substantially of burnt lean gas of the carbonization, and, for each stage, the hot gases are recirculated in a separate respective circuit. In the preheating, dehydrating and carbonization stages, the hot gases are heated and produced, or supplemented, in a respective separate combustion chamber with the recirculating hot gas in the carbonization stage being supplemented with cooled lean gas from this stage. The recirculating hot gases are dedusted separately in a dust settling chamber in which their flow velocity is reduced to approximately 0.2 to 2.0 m/sec, with the dust being collected. Steam may be added to the recirculating hot gas of the preheating stage, drying stage, or both, and the pressure in the hot gas circuits is maintained at a level slightly higher than atmospheric pressure. The oven chambers are arranged as a vertical oven block plant and the oven chambers are interconnected with each other by transition zones which are conically narrowed to approximately one half of the cross section of the chamber and then widened up to the full cross section. The hot gas inlets are provided in the transition zones at the lower ends of the oven chambers, and the hot gas outlets are provided in the transition zones at the upper ends of the chambers. The dust settling chambers are provided immediately adjacent the hot gas outlets, and the carbonization chamber is surrounded by its combustion chamber to form an operating unit. SPCROSS-REFERENCE TO RELATED APPLICATIONSThis is a continuation of application Ser. No. 660,153, filed Feb. 23, 1976, now abandoned.

摘要： The invention concerns a process for removing dust from coke cooled by a dry method after the coke has left the cooling zone of a cooling chamber, and a device for carrying out the process. A dust-free flushing gas is injected below the cooling zone, preferably parallel to the direction in which the coke moves when it has been cooled to below 200.degree. C., to draw the gas off above the discharge lock together with the stirred-up coke dust, and to recirculate the gas after the dust is removed from it. As an alternative, compressed air is blown through the coke after it has left the lock and while it is being transported through a vibrating machine. The coke is cooled in a dry cooling unit to below 200.degree. C. and preferably 130.degree. to 180.degree. C. The coke is then cooled outside the dry cooling unit by means of air at about 50.degree. to 90.degree. C. and preferably 70.degree. to 80.degree. C. Either simultaneously with or immediately after the cooling step with air, the coke is moistened, for example by sprinkling or spraying, to a residual moisture of 2% to 4% by weight and preferably 2% to 3% by weight.

摘要： Briquettes made from bituminous or sub-bituminous coal or peat are produced by grinding the coal, mixing it with a binder and compacting the mixture. They are then carbonized in a continuous process in a shaft oven. The coal may be predried and the finished briquettes may be preheated, with a subsequent drying and hardening. The carbonization is effected in two stages in an indirectly heated shaft oven, with the evolved gas being taken off about at the mid-height of the oven shaft, processed, and used for heating in the second, high-temperature stage. The flue gases from this high-temperature stage are used for heating in the first stage and for preheating. The second or high-temperature stage is followed by a cooling stage where the gases evolved in the second stage, and mainly comprising hydrogen are used and circulated. The evolved gas in excess is continuously removed from the cooling circuit.

摘要： Abrasion-proof coke forms are produced from bituminous coal, brown coal, or peat in the form of briquets, by preheating the briquets, dehydrating or predrying them, carbonizing them and then cooling them in at least three separate stages in which the briquets are dehydrated indirectly by subjecting them to indirect temperature conditions, producing a temperature gradient in the briquets. The briquets are automatically fed into a shaft tower which includes an upper drying shaft portion made up of a plurality of stacked radiators which include tube elements for the passing of a heating fluid, such as steam, therethrough and which define vertical shaft passages through which the briquet forms are passed downwardly and into a carbonizing shaft which has separate gas channels for directing heating gases therethrough and to a heating flue and which subsequently includes a lower cooling zone through which the briquets pass and then into a discharge channel where they are delivered for classification.
