Coke oven

摘要

According to the invention, the heating flues in coke ovens are in each case provided with at least two gas supply lines and each heating flue is assigned at least two air supply lines in order to be able to increase a heating-flue temperature selectively in the case of a locally required increase in the wall temperature in the coke oven, or in order to be able to ensure continued air supply in the event of damage to the air supply to a heating flue.
