Glowing coke is discharged from an oven chamber 1 into a closed container 7 which the coke traverses spread-out on a conveyor grating 11 while being quenched with water from a pipe system 16 and nozzles 15, vapours and entrained coke particles from the conveyer being precipitated in a chimney-like extension 19 of the container 7 by water from nozzles 20. The container 7 is mounted on a chassis 6 and runs on rails 3, 4 and 5 so that it may be moved along the coke oven battery 2 to the chamber to be discharged. The chamber door is removed by a hoisting mechanism (not shown) mounted on the chassis 6 and a telescopic guide unit 9 of the container 7 is extended and pressed against the door frame. Coke is discharged through the unit 9 into a reception space 10, whose capacity is that of an oven chamber charge, and the guide unit 9 is retracted so that it seals off the space 10 from the outside atmosphere, the oven chamber door then being replaced. Vapours from the space 10 pass into the chimney 19 through orifices 28 while the unit 9 is extended. Coke passes from the space 10 along the conveyer grating 11 to be quenched and the thickness of the coke layer on the conveyer is controlled by a partition 14 hinged at 13. Quenched coke from the conveyer falls through an opening 17 on to a further conveyer 18. Alternatively a swivelling conveyer unit may be disposed below the opening 17 and discharge coke on to a ramp. Water for the quenching nozzles 15 and for the chimney nozzles 20 is drawn by a pump 21 from a trough 23 laid along the track of the container 7. Water from the chimney 19 is caught in a channel 24 on the partition 14 and is guided past the conveyer 11 to drain, together with the quenching water from the conveyer 11, through a stub pipe 25 into a trough 26 from which it is returned via a settling tank to the fresh water trough 23. Means for displacing the partition 14, varying the speed of the conveyer and adjusting valves in the quenching pipe system 16 are jointly or separately operated from a driver's platform or cabin 27, as also are the mechanisms for removing the coke oven doors and for operating the guide unit 9.
