  • Patent number: 4147594
    Abstract: A cylindrical drum having a lining spaced apart from the shell of the drum is rotatably mounted on a frame movable on rails along the coke side of a coke oven battery. A fume shield is fixed to the frame and covers openings in the shell and lining through which hot coke passes, when pushed from a coke oven chamber. A hood is fixed to the structure supporting a coke guide and has a movable portion that coacts with the rotatable shell when coke gravitates into the shell. The drum is rotatable to several operative positions.

A movable cover is fixed to the shell and covers the opening in the shell through which hot coke passes, when pushed from a coke oven chamber. A hood is fixed to the structure supporting a coke guide and has a movable portion that coacts with the rotatable shell when coke gravitates into the shell. The drum is rotatable to several positions. Means are included to quench the hot coke and to extract the particulate laden steam which is generated by the quenching operation. Additional means are included to remove noxious gases and particulate matter which emanates from the hot coke.

  • Patent number: 4004985
    Abstract: A quenching track extends alongside of and away from a coke oven battery, and coke receiving apparatus is movable on the track to a remote location at which supporting structure for the coke receiving apparatus is located. Associated with the supporting structure is conveyor means onto which incandescent coke is discharged from the coke receiving apparatus. Coke on the conveyor means is quenched, and vapors arising from the coke during quenching are conveyed to a stack and are discharged to the atmosphere. Fumes arising from the coke receiving means during discharging of the coke are withdrawn into a gas scrubber and cleaned therein. From the scrubber the cleaned fumes are discharged to the stack and to the atmosphere.Various types of coke receiving means are disclosed, and various types of supporting means and arrangements of conveyors at the remote location are also disclosed.
