Abstract: Flue gas discharged from a recuperator or regenerator of a coke oven battery has the steam thereof removed by means of a direct or indirect cooling and condensation operation. After the steam is removed from the flue gas it is then passed through a coke dry cooling plant in direct contact with hot coke therein to form dry cooled coke while simultaneously increasing the temperature of the flue gas.

The entire system is open, such that a given quantity of the flue gas passes only once through the system. When the temperature of the flue gas as received from a coke oven battery is extremely high, then the flue gas may be subjected to a partial cooling operation prior to the cooling and condensation operation.
