CA 2362455

The invention relates to a method of hot-repairing the heating flues of a coke- -oven battery according to which the completed sections of a heating flue still un- der construction are heated by means of a heated gas. As heated gas the air usually provided for combustion in heating flues during coking operations is used. This air is guided through the flow paths provided for in the coke-oven battery for combustion air and waste gases as well as through the regenerator, heated as it passes through said paths and then guided through the heating flues to be re- paired. The completed section of the heating flue is separated from the part still to be constructed by an air-reversion device.

L'invention concerne un procédé de réparation des carneaux de chauffage d'une batterie de fours à coke selon lequel il intervient un chauffage des sections déjà terminées de chacun des carneaux de chauffage à l'aide de gaz chaud, dès le moment où les carneaux de chauffage sont en cours de construction. Le gaz chaud utilisé est l'air prévu de manière générale dans les carneaux de chauffage pour la combustion en mode de cokéfaction. Cet air est guidé à travers les voies d'écoulement présentes dans la batterie de fours à coke pour l'air de combustion et les gaz brûlés, y compris à travers le régénérateur, et se trouve chauffé à cette occasion avant d'être guidé à travers les carneaux de chauffage à réparer. La partie du carneau de chauffage dont la construction est terminée est séparée de celle qui doit être terminée, par un dispositif d'inversion d'air.
