The sealing surfaces of a coke oven door are cleaned with high-pressure fluid by a hydraulically operated high-pressure piston pump which displaces either a hot or a cool conveyed media ladened with solid particles such as a coal mass and a fluid for cleansing the sealing surfaces of the coke oven doors and door frames. The pump includes a closed pump cylinder having an inlet and outlet valve for a conveyed medium at both ends of the cylinder and a partition dividing the cylinder. Inlet and outlet valves for hydraulic fluid are located in the cylinder on each side of the partition. An inner double piston is axially movable to and fro with the cylinder and comprises two output piston portions with a piston rod connected to each portion and located between them guided on bearings in the cylinder. A delivery space is formed between the piston portions and each end of the pump cylinder and the respective delivery spaces at each end simultaneously and oppositely decrease and increase during an operation. The hydraulic space is formed between the piston portions at each side of the partition and the hydraulic space also simultaneously and oppositely increase and decrease during operation. The pump is connected to a coke door cleaning apparatus for the purpose of cleaning an annular sealing surface. The apparatus includes a generally rectangular annular sealing surface trackway around the sealing surfaces of the door and a support structure adjacent the sealing surface having a sliding support surface trackway adjacent the door. A sliding support moves over the support surface. A nozzle lance is carried on the support and has an end with a nozzle directed at the sealing surface and an opposite end with a cleaning liquid connection through a hose to the high-pressure piston pump.

A method of dry cooling coke using a coke transporting bucket which has a removable cover with an exhaust pipe extending from the interior of the bucket to an exterior exhaust connection and a cooling shaft for the coke comprises directing red hot coke into the bucket, covering the bucket with the cover and transporting the coke to the cooling shaft and connecting the exhaust pipe to the exhaust system while the bucket is in the shaft and emptying the bucket into the cooling shaft. The coke transporting bucket comprises a container having a bottom discharge which is closable by a flap and a removable cover which seats around the rim of the container to seal it. An exhaust pipe is carried by the cover and it extends into the interior thereof for removing gases from within the bucket and delivering them to an exterior connection which is connectable to an exhaust line. One or two exhaust pipes may be provided on the cover and each includes cover flaps which are biased into a closed position but which open to connect to the exhaust system when the cover is positioned to engage the exhaust line. The cover advantageously includes longitudinal girders which extend outwardly from each side or end of the cover and provide a means for supporting the cover when the bucket is lowered beneath a support structure to free the cover from the bucket.

Method for dry cooling coke

A method for the dry cooling of coke comprises transferring the coke from the coke oven to a special bucket which is moved over a charging hole of a cooling pit. The space between the bucket and the charging hole is closed off and sealed against the atmosphere and a shutter which closes the top of the charging hole is moved upwardly and then transversely off the charging hole to open it as an intermediate charging guide piece is moved in position between the hole and the bucket for the transfer of the coke therebetween. The space between the bucket and the charging hole is sealed by a frame of a sluicing device in which the shutter and the intermediate charging hole guidepiece is movable. The device advantageously runs on wheels which are located outside the frame which seals the sapce between the charging bucket and the charging pit. The frame of the sluicing device advantageously includes a sealing element which engage into a recess seal combined around the charging hole.

A sealing arrangement at coke oven chambers, for gastightly sealing the junction gaps between a transfer means, such as provided on coke guide cars or at the pushing machine and the coke oven, comprises sealing sheets at the oven side, which in operating position, apply against the outside of the chamber opening. The inner space of this transfer means is connected to stationary exhausters, for example. The sealing sheets comprise a plurality of individual segments which, as the transfer means is put in place, are pressed by adjustable springs acting through sliding rods against anchor posts and, at the top of the chamber opening against plates connected between the anchor posts at the top of the chamber.

A gas collecting hood for taking off emissions from coke being pushed out of coke oven chambers, travels along with a coke guide alongside the battery. The hood is connected through a gas collecting duct to a stationary exhausting system. The hood is supported at three points, through roller (15,16) at two points (A,B) on a rail (11) which is provided at the hood side remote from the coke guide (3), and pivotally at a point (C) on the coke guide (3).
