A method for compensating flue gas enthalpy losses of heat-recovery coke ovens is disclosed. In a plant a plurality of coke oven chambers (1) are combined into a coke oven bank (2). The coke oven bank is connected to one or more boilers (7) by means of one or more flue gas channels (6). If operation of the coke oven chambers is interrupted, to remove the coke cake, the individual coke oven chambers are kept hot during the interruption of the operation by means of at least one externally fired additional burner (3). The heat is provided by hot flue gas originating from the flue gas of the additional burners. Heat flow that is reduced in comparison to the normal operation is further compensated by at least one additional compensation burner (10), which lies outside the coke oven chambers such that the boiler(s) are supplied with a heat flow that remains the same in comparison to the normal operation. In this way, the boilers, which are typically used to produce steam, can be operated economically. |
