Abstract: 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.

Abstract: 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.

Abstract: 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.
