Patent number: 4370202Abstract: A coke cooler and method of operating the cooler is disclosed for dry cooling hot glowing coke through the recovery of the sensible heat of the hot glowing coke. The apparatus includes a vertically elongated vessel having walls partially formed with integral heat exchange tubes for the passage of a liquid coolant and a shroud having an internal prechamber mounted in the upper end of the vessel for receiving a charge of the hot glowing coke. The shroud cooperates with the vessel to provide a annular passage for fluid flow therebetween of a gas which directly contacts the hot glowing coke for direct cooling while liquid coolant is passed through the tubes for indirectly cooling the coke.Type: GrantFiled: November 19, 1980Date of Patent: January 25, 1983Inventors: Heinrich Weber, Kurt Lorenz, Horst Dungs

Patent number: 4354903Abstract: A three-cycle process as disclosed for drying and preheating coking coal using the heat from cooled coke. Cooling gas is passed over hot coke to heat the cooling gas and cool the coke. The heated cooling gas is then passed through a waste heat boiler and then back to the hot coke in a coke cooling chamber. This completes the first closed cycle. Water is supplied to the waste heat boiler to form steam. The steam is supplied to a fluidized bed of wet coal to indirectly preheat and dry the wet coal in a second cycle. The wet coal is fluidized using fluidizing gas which converts water in the wet coal into steam. Some of the steam is condensed from the combination of fluidizing gas plus steam and then the fluidizing gas is returned to the bed. Steam from the waste heat boiler is also supplied to the fluidizing gas before it re-enters the bed to heat the fluidizing gas.Type: GrantFiled: March 30, 1981Date of Patent: October 19, 1982Assignee: Firma Carl Still GmbH & Co. KGInventors: Heinrich Weber, Kurt Lorenz, Horst Dungs

Patent number: 4338161Abstract: An apparatus and arrangement is disclosed for cooling glowing coke in a dry circuit which utilizes a cooling chamber divided by cooling walls into a plurality of parallel vertically extending cooling channels. The cooling walls are supplied with a cooling medium for indirectly cooling the glowing coke. A coke discharge mechanism in the form of a chute having a comb-like end and paddle wheels between the teeth of the comb is provided at the bottom of each cooling channel to discharge coke from the cooling chamber in a controlled fashion to an underlying after-chamber. Each cooling channel is provided with cooling gas for directly cooling the glowing coke. An arrangement utilizing the apparatus supplies cooling gas directly to the cooling channels which, after passing out of the cooling chamber, passes into a waste heat boiler which is supplied with water so that it is heated by the now hot cooling gas to produce steam.Type: GrantFiled: March 30, 1981Date of Patent: July 6, 1982Assignee: Firma Carl Still GmbH & Co.
