There are already various options for extracting the filling gases from coking ovens arranged in batteries Suggestions have been made. All known suggestions for permanently installed suction lines, starting from an opening in the furnace roof, however, are more or less dependent on the fact that the Often a part of the fine coal flow flowing through the filling holes of a coking furnace Chamber space locks off, so that the filling gases are no longer sufficiently sucked out of the sealed off part and thus to considerable smoke and dust nuisance on the furnace roof and also in the vicinity of the furnace system.

It has also been proposed to use the hopper of the hopper by means of an or several fans, which are mounted on the filling carriage, if necessary with the activation of Washing systems for wet dedusting, suction. This, however, is the filling car with additional Apparatus strained and its operation awkward.

To render harmless when filling and emptying coking ovens from the oven and a device is known in which, for example, gases and vapors escaping from the riser pipe the gases and vapors in a placed in the furnace ceiling, through the radiating furnace heat permanently kept in embers, not connected to the heating system of the furnace chambers Combustion channel to be burned for itself.

It is also a suction and incineration process during filling, cooking and emptying Gases produced by coke oven chambers are known, in which a mobile chimney-like exhaust device is used and the extraction device provided with refractory lining is always kept at such a high temperature inside that the gases previously mixed with air are burned.

It is also known to arrange connecting channels equipped with slides or valves in the furnace ceiling between adjacent furnace chambers, through which intermediate gases occurring during operation of the furnace chambers are transferred into adjacent chambers. Also known is a device for discharging the filling gases occurring when charging the coking ovens, in which the gas outlet for the distillation gases is connected to the filling gas collecting line by a secondary line which is controlled by a valve which is usually closed and which is opened when the furnace is being charged , this valve from the device for sucking off the filling gases

Oven position automatically up to the full final position and is gradually closed.

There is also a riser system for coking ovens known with a special line to Suction of the filling gases are provided, the line for the filling gases at the lower end of the riser pipe is branched off so that the shut-off valve when cleaning the riser pipe Riser pipe as a collecting tray for the falling tar particles, etc. can serve.

Finally, it is also known to post the filling gases through a duct located in the upper masonry suction towards the chimney. You can use the filling gases to avoid. Explosions indifferent Combustion gases of the coking ovens are added.

The known methods do not exclude deflagrations and explosions with complete certainty, and in the known devices parts of the coking furnace battery itself are in this case or the suction devices are damaged.

A device is proposed to reduce the likelihood of deflagrations or explosions take place, takes into account and which in such a case does not suffer any damage.

The device according to the invention for sucking off the filling gases from coking ovens arranged in batteries with feet and suction channels of trough-like cross-section in the furnace roof, which are connected to the interior of the furnace through openings and via locking slides in one along the Battery arranged similar collecting channel open, is characterized in that at each Filling hole of the coke oven chamber laterally at least one for each oven chamber and with the oven interior Suction channel connected only via the filling holes with lifted filling hole covers
