Method of keeping sprinkling water used for sprinkling in the uptakes of coke ovens in a clean condition, comprises directing the sprinkling water condensate which is collected after circulation in the uptakes, and which includes tar, tar oils, hydrocarbons and ammonia, into a separator to separate a clean sprinkling liquid therefrom, and returning this liquid to the flue and also directing a tar which is free of solids into the flue with the sprinkling liquid, at least during an initial period of operation of the coking oven.
