The invention relates to a method for compensating flue gas enthalpy losses of heat-recovery coke ovens, wherein a plurality of coke oven chambers are combined into a coke oven bank, and the coke oven bank is connected to one or more boilers by means of a flue gas channel or flue gas channels. The operation of the coke oven chambers is periodically interrupted, during which time the coke cake is removed, and the individual coke oven chambers are kept hot during the interruption of the operation by means of at least one externally fired additional burner such that a hot flue gas is provided even during the interruption of the operation, the hot flue gas originating from the flue gas of the additional burners, and the heat flow reduced in comparison to the normal operation is compensated by at least one additional compensation burner, 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.
