  • Patent number: 10233392
    Abstract: The present technology is generally directed to methods of increasing coal processing rates for coke ovens. In various embodiments, the present technology is applied to methods of coking relatively small coal charges over relatively short time periods, resulting in an increase in coal processing rate. In some embodiments, a coal charging system includes a charging head having opposing wings that extend outwardly and forwardly from the charging head, leaving an open pathway through which coal may be directed toward side edges of the coal bed. In other embodiments, an extrusion plate is positioned on a rearward face of the charging head and oriented to engage and compress coal as the coal is charged along a length of the coking oven. In other embodiments, a false door system includes a false door that is vertically oriented to maximize an amount of coal being charged into the oven.

  • Patent number: 9034147
    Abstract: A method for reducing the coking time in the oven area near the door or end wall and for improving coke quality and situation of emissions by compensating for radiation losses through coke oven chamber doors and end walls is described. This compensation is accomplished by varying the height of the coal cake in the environment of the frontal coke oven chamber doors. The variation is achieved both by increasing or decreasing the coal cake over part of the length or over the entire length of the coke oven chamber door. The reduction in the height of the coal cake can be generated by omission of coal or coal compacts, the increase in height can be accomplished by stacking of coal and pressing or adding of coal compacts, with it also being envisaged to omit the pressing cycle so as to obtain a recess with a lower coal cake density which also has less heat radiation.

A clay feed is extruded to provide a hollow tube of compressed clay supported inside of the coal tube and a combustible fuel is burned inside of the clay tube. The temperature of combustion is sufficient to fire the extruded clay and pyrolyze the extruded coal to produce hydrocarbon gases and coal char. The support tube has holes for releasing the hydrocarbon gases, which contain suspended particles formed during combustion. The suspended particles are removed from the hydrocarbon gases to provide clean gases, which are passed through an ionizing chamber to ionize at least a portion thereof.

    Abstract: This invention discloses a new method for the production of coke from coals. In the present invention, coke is continuously produced by heating a moving charge of coal inside the annular space between two tubes. The coking chamber, which includes a large tube and a smaller tube, is force-fed with a coal such as a metallurgical coal. The coal is bi-directionally heated along a controlled temperature gradient between the outer wall of the small tube and the inner wall of the large tube. The coal is transformed to coke as it travels through the annulus of the coking chamber. Coke is discharged from the chamber at the end opposite to which it was charged and is cooled before being exposed to the atmosphere. Gases generated during the coking process are collected and treated. All of these operations are accomplished in a closed system to prevent pollution.

  • Patent number: 5447606
    Abstract: Individual coke ovens in a nonrecovery coke oven battery are charged through an open door at the pushing end of the ovens, and emissions escaping through the open door of the respective ovens during charging are captured by a hood mounted on the pushing and charging machine for movement therewith along the pushing side of the battery and for movement thereon from a retracted position spaced outwardly from the ovens and a capturing position above the open oven door. Air and emissions captured by the hood are withdrawn and passed through an air cleaner mounted on the pushing and charging machine to remove smoke and particulates before being discharged to the atmosphere.

  • Patent number: 5084140
    Abstract: The macromolecular waste (which is not itself susceptible to microwave heating and may be, for example, plastics or polychlorinated biphenyl) is mixed (B) with pulverulent carbonaceous material, which comprises elemental carbon or is degradable by microwave irradiation to elemental carbon (such as waste tire material). The mix is subjected to microwave irradiation (C) in an inert atmosphere to cause pyrolysis of the plastics. Preferably part of the resulting solids is recycled to the microwave zone (C).

  • Patent number: 4555209
    Abstract: A leveler bar for a coke oven is controlled in its travel toward and away from the coke side of the oven by semi-automatic means to move the leveler bar during a "cycle" mode through half strokes and during the "finish" mode it performs four "full" strokes of which a full stroke can mean a 3/4 distance of full travel across the oven. Electrical circuitry which modifies or adds to prior art circuitry to accomplish this leveler bar movement is included herein.

  • Patent number: 4491505
    Abstract: A coal-leveling apparatus includes a leveling rod supported by a pressing machine for movement through a leveling opening into a mushroom-shaped gas-collecting space to level the coal charged in the coking chamber of a coke oven. The leveling rod includes a head element that carries two support members that can move on pivot levers between an operative position wherein the support members are extended from the head element for support by upwardly-inclined wall surfaces in the mushroom-shaped gas-collecting space. In the inoperative position, the support members are retracted toward both sides of the head element. An actuating rod extends through the leveling rod to the head element. In one embodiment, the actuating rod can be moved in opposite directions of its length. An end of each of the first pivot levers is connected to the actuating rod and the opposite ends of the first levers are connected to second pivot levers.

  • Patent number: 4462869
    Abstract: A method and apparatus for conveying preheated coal particles to a coking chamber through an enclosed pipeline by means of a pressurized inert carrier gas, wherein the coal particles are charged into the top of the coking chamber through a portion of the pipeline wherein at least the end of which is disposed vertically or not more than from vertical. The advantages of the top charging technique include one or more of the following: reduced carryover of fine coal during charging, increased density of the charge of coal to be coked, reduced weight of carrier gas per unit weight of coal, improved uniformity of coal bed level throughout the coking chamber, and reduced carbon deposits on surfaces of the chamber above the coal charge and in the gas off-takes.

  • Patent number: 4276120
    Abstract: A process and apparatus are disclosed for purification of petroleum coke to produce an economical low sulfur product suitable for electrode production. Finely ground green coke is treated on an enclosed circular grate apparatus and subjected to sequential treatments in which hot gases are passed through a deep permeable bed of coke on the grate in a series of separate treating zones including a preheat zone, a heating and calcining zone, a desulfurizing zone in which hydrogen rich gas is passed through the heated bed, a reduction gas generation zone in which hydrocarbon and steam pass through hot coke to form hydrogen, and a cooling zone.Adequate temperatures for calcination and desulfurization are achieved and the proper heating rate is obtained without overheating the metal parts of the hearth by use of radiant and hot gas heating means in the calcining zone and in the desulfurizing zone and by introducing the air and/or fuel gas near the bottom of the coke bed.
