A waste heat removal system for a regenerative coke oven battery which has side burners and a regenerator portion comprises a plurality of substantially parallel longitudinally extending channels of substantially equal cross section which are defined in the battery at spaced lateral locations and extend over substantially the entire length of the battery below the regenerator portion. A common transversely extending collecting duct adjacent one end of the battery is connected to each of the channels. A waste heat collection duct is disposed along at least one side of the channels and it is associated with a selective portion of the regenerator and a long cross channel is connected to the waste heat connection duct and to selected ones of the channels. The cross channels extend from the pusher side to the coke side or vice versa and form alternately short and long connections to corresponding longitudinal channels. The first cross channel at the side remote from the flue or chimney has a smaller passage opening leading into each of the longitudinal channels.

An earthquake-proof foundation for a lateral burner-type coke oven battery, comprising, a foundation baseplate connected to the ground, a mounting plate positioned above the baseplate for supporting the coke oven battery and a plurality of sliding devices interposed and connected between the mounting plate and the foundation baseplate to permit lateral and transverse displacement of the mounting plate with respect to the baseplate. The mounting plate includes a plurality of openings and ferroconcrete pegs are bonded to the foundation baseplate and extend upwardly into the mounting plate opening. Elastic elements are connected between the ferroconcrete pegs and the edges of their associated openings to resist transverse and lateral displacement of the mounting plate with respect to the foundation baseplate.

A horizontal coke oven battery construction in which a pusher is mounted to extend into the batteries from one side and push coke out of the batteries on the opposite side, comprises a plurality of coke oven batteries disposed in a row. A first waste gas flue extends along the pusher side of the batteries and a second waste gas flue extends along the coke side. A stack flue at one end of the batteries is connected to the first and second waste gas flues. The construction includes means for directing the heating gases into each oven battery during operation so that, in respect to the pusher and coke size, approximately one-half of the batteries is heated by upward burning and the other half is heated by downward burning. For example, all odd numbered batteries may be heated in the same direction and all even numbered batteries heated in the same direction. The invention also comprises a two-section regenerative heating system having reversing winches wherein the heating on one-half or approximately one-half of the oven chambers is equipped for upward burning and the heating of the other half is equipped with downward burning. Between the two halves, a center head maybe be provided, or only one reversing winch may be provided at the end of the battery.

Method of operating horizontal coke oven batteries

An apparatus for quenching glowing coke in a coke-quenching container or car, comprises a housing with spaced front and rear vertical walls and vertical end walls at each end having respective entrance and exit openings for the quenching car. The housing also has a ceiling portion adjacent the upper end of a vertically elongated gas chamber defined within the housing and it communicates adjacent the rear wall with an upwardly extending flue. In order to ensure that any sensing devices in the flue are not influenced by the direct radiation from the glowing coke of the quenching car positioned in the chamber, the device includes a baffle extending outwardly from the rear wall and covers a cross-sectional area in the quenching chamber, but leaves a free gas flow cross-section for the flow of quenching gases which is as large as the area covered by the baffle.

Regenerative heating system for horizontal coke oven batteries

A method for clarifying coke quenching water or other waters which are contaminated by solids, with a wide grain spectrum, in an operation in which the fine portions of the solids suspended and carried along with the water are removed from the water by filtration and the clarified water is returned in a cycle, comprising, depositing the water into a filter shaft so that the substances removed from the contaminated water build up in the shaft and themselves form a filter bed, continuing to pass the water through the filter bed from the top to the bottom in a manner so that the velocity of flow of the water in the filter bed decreases constantly and so as to preclarify the water which passes through the bed and subsequently refiltering the preclarified water in a trough basin which rises from the bottom to the top. Thereafter, the refiltered water is directed into a discharge channel from the trough basin which overflows above the basin. During the operation, the bottom of the bed is continuously broken down by mechanical means, such as a screw conveyor, as the top is continuously replenished by directing the solid-containing quenching water into the top of the filter shaft.

A settling unit for coke quenching water, which is circulated in a closed cycle, comprises a settling basin having substantially vertical side walls with a drain surface sloping downwardly alongside one of the sidewalls and a conduit for the quenching water disposed between the drain and the sidewall in a position to supply quenching water to the settling basin along the entire width of the sidewall and also to receive drained water from the drain surface. A trackway is defined above the basin and the drain surface and it includes a dredging carriage which is movable therealong having a dredging bucket which may be manipulated to pick up the solids from the basin or from the drain surface and to deposit them on the drain surface as necessary.

Settling unit for circulated coke quenching water

The device is positioned in a stack arranged above a location where coke quenching is performed. The coke quenching, which takes place below the stack, evolves steam and gases containing solid coke particles or dust, and which must be prevented from passing into the outside atmosphere. The steam and gases flow upwardly through the stack and the device separates the solid coke particles and dust from the steam and gases. The device comprises a support beam carrying a plurality of shutter-like baffles, of plastic material, and liquid spray elements, and which is variable in length and positioned either obliquely or horizontally across the upper portion of the stack. In between successive coke quenching operations, the liquid spray elements are activated to flush the trapped solid coke particles and dust from the shutter-like baffles. The adjustable length of the device provides for the device to be positioned to extend across the stack at varying angles, or even horizontally. The device may be pivoted at either end of the stack so that it may be swung about the pivot to vary the angle of inclination of the device in the stack, and the adjustable length of the device accommodates the various oblique positions or the horizontal position. The support beam advantageously is supported by a diagonal brace extending from one wall of the stack to the support beam.

The device for pushing incandescent coke out of individual chambers of a coke oven battery which has a plurality of horizontally arranged coke oven chambers, comprises a trackway of spaced apart inboard and outboard tracks which extend along the length of the coke oven battery and a gantry-like carriage which is movable over the trackway and carries the apparatus for pushing the coke out of the individual batteries. The carriage includes inboard legs which are elastically connected to a platform portion which contains the movable ram and other operating parts and outboard legs which are rigidly connected to the platform. The outboard legs also carry contact pressure mechanisms which connect between the legs and the outboard tracks for distributing horizontal stresses to the tracks.
