  • Patent number: 8980063
    Abstract: A device for proportioning of secondary combustion air into the secondary air soles of coke oven chamber ovens is shown. The device is formed by a slide gate or a parallelepiped device or by plates moved by means of a thrust bar, the thrust bar being moved longitudinally in parallel to the coke oven chamber wall so that the plates move away from the secondary air apertures and open or close these. The thrust bar is moved by means of a positioning motor, with the power transmission being effected hydraulically or pneumatically. Via suitable measuring parameters, it is thus possible to optimize secondary heating so that heating is provided evenly from all sides, thus achieving an improvement in coke quality.

  • Patent number: 8105400
    Abstract: A process for treating biomass comprises providing a material that contains an amount of residual moisture. The material is heated to a torrefying temperature in a low-oxygen atmosphere in a torrefaction reactor to convert it into a torrefied material. The material with the contained residual moisture is essentially fully dried in a drying chamber by evaporation of residual moisture. The torrefaction reactor comprises a torrefying chamber, in which the torrefaction of this dried material is essentially carried out. The material is conveyed through the torrefaction reactor. The drying of the material in the drying chamber is carried out by introducing into it a hot drying gas that flows therethrough cocurrently with the material. The torrefaction of the material in the torrefying chamber of the torrefaction reactor is carried out by introducing into it a hot torrefying gas that flows through the torrefying chamber countercurrently with the material.

  • Patent number: 5318672
    Abstract: A method and an apparatus for heating a carbonization drum is especially used for heating a carbonization drum for a low-temperature-carbonization combustion process. Heating gas heated in a heat exchanger is guided in a heating gas loop from the heat exchanger through the carbonization drum. A heat sink is provided for cooling the heating gas. In order to control an energy supply to the carbonization drum, the heating gas is guided back again at least partially and in a controlled fashion through a bypass line, in which the heat sink is disposed, to the heat exchanger, while bypassing the carbonization drum. The heating gas can also be delivered partially and in a controlled fashion through the heat sink to the carbonization drum. A distribution of the heating gas into a maximum of three paths is ensured by a configuration of lines and control devices.

  • Patent number: 4341620
    Abstract: Hydrocarbon containing oil shale is processed on the surface of a rabbled rotary hearth by mixing it with a heat exchange medium consisting of heated spent oil shale. Mixing is obtained by feeding the raw shale and the heated spent shale separately, but in proximity to one another, onto the surface of a hearth, and then subjecting both materials to rabbling action. This mixing causes heat from the heated spent shale heat exchange medium to be transferred to the fresh raw shale, which results in the removal of hydrocarbons from the raw shale. In one preferred embodiment, heated spent shale is obtained by removing spent shale from the hearth after processing, mixing it, preferably while it is still hot, with compatible combustible solids, and then introducing oxidizing gases into the mixture. This results in the burning of the combustible solids and any combustible materials remaining in the shale and the heating of the spent shale.

  • Patent number: 4274941
    Abstract: Fine grained coal is fed into a first chamber of a generally horizontally extending fluidizing bed reactor while a stream of hot solid heat exchange material is passed through the chamber. The coal is then subjected to a fluidizing action with a low nitrogen and low oxygen content so as to degas the coal particles and obtain the combustible gases and liquid byproducts. The coke particles thus formed are then passed into an adjoining second chamber which acts as the combustion chamber and are subjected therein to fluidization with air and burning. Steam is generated in water-filled conduits passing through said second chamber. The heat exchanger particles are simultaneously heated up and are continuously fed back into the first zone of the reactor to contact fresh coal introduced thereinto.
