  • Patent number: 4973337
    Abstract: The arrangement for cooling a hot product gas containing adhesive or fusible particles which lose their adhesiveness during cooling, has a reactor for producing the hot product gas, a cooling duct connected with the reactor for the hot product gas, a nozzle ring subdivided into a plurality of chambers mounted adjacent to and communicating with the cooling duct, each of the chambers being structured to introduce a different ring-shaped jet of cooling fluid into the hot product gas in the cooling duct. The different ring-shaped jets are producible with mass and penetration depths according to the mass of a product gas stream flowing in a cooling zone of the cooling duct with injection speeds selected to obtain a predetermined penetration depth. Using different penetration depths for the different ring-shaped jets allows avoidance of baked deposits on the walls of the reactor and cooling duct.

  • Patent number: 4954136
    Abstract: A method for cooling a hot product gas containing adhesive or fusible particles include injecting a ring-shaped jet of a cooling fluid into a gas to be cooled in a cooling zone in a flow direction of the gas, with separation of the jet into a plurality of individual cooling fluid jets with mass and penetration depths corresponding to the mass of product gas streams flowing through individual ring-shaped parts of the cooling zone. The injection speed of the cooling fluid jets are selected so as to obtain a desired penetration depth.

  • Patent number: 4842695
    Abstract: A dry cooling installation for coke includes an upright cooling shaft having an upper inlet for coke to be cooled and a lower inlet for a recirculating counterstream of cooling gas. Two gas discharge ducts are connected at two opposite points to the cooling shaft and communicate respectively with dust separators. A waste gas heat boiler is arranged between the separator and communicates with the same so as to receive clean gas in a direction which is substantially perpendicular to the movement of separated dust particles.

  • Patent number: 4486269
    Abstract: Cooling of a gas-permeable loose material having highly temperature-dependent coefficient of thermal conductivity is performed in a shaft-shaped chamber with use of a gaseous cooling medium so that the loose material is fed from above downwardly in a counter stream against a stream of the gaseous medium supplied from below upwardly. The stream of the gaseous medium is subdivided into two partial streams, and one of the partial streams is supplied into the lower part of the chamber, whereas the other of the partial streams is supplied into a region in which the loose material has at least a temperature above which the coefficient of thermal conductivity of the loose material in dependence upon the temperature greatly increases.

  • Patent number: 4470878
    Abstract: In a coking process, coal to be coked is preheated in a cascaded whirling bed drier into which the coal is charged from above and exposed to an indirect heat transfer while whirling in a coal-stream mixture. Hot gas applied to the heating pipes in respective cascades of the drier is branched off from the total amount of hot gases discharged from a dry cooler in which hot coke from the coke oven is cooled by recirculating cooler gas constituted by a partial gas stream discharged from the cascades of the drier and reunited with the other partial stream subject to a heat exchange for generating steam. Steam from the whirling beds is discharged from the cascaded drier, separated from the entrained dust particles, and then the excessive steam is drained in a branch conduit and the remaining steam is compressed and reintroduced into the lowermost whirling bed in the drier.

  • Patent number: 4469559
    Abstract: A container for transporting hot coke has a cylindrical portion and a narrowing conical portion downwardly extended therefrom. A rotation ring carrying grippers is positioned in the upper region of the container, which is operated during the filling of the container with coke.

  • Patent number: 4342626
    Abstract: A cooling device for coke dry cooling, has a housing composed of upper and lower parts connected with one another by a slide joint, and a ring-shaped insert located inside the upper part of the housing and constituted of a metallic heat-resistant material, coated by a wear-resistant and heat-resistant coating layer. The insert is conical and mounted by its upper end portion on the upper part of the housing.

  • Patent number: 4333910
    Abstract: An arrangement for discharging coke from a cooling shaft supplied with cooling gas, has one or several coke stripping members arranged to engage in a mass of coke discharged from the cooling shaft, a supporting element for supporting stripping members and rotating together with the latter, and a housing in which the supporting element together with the coke stripping member are accommodated and which is sealed from the atmosphere.
