Patent number: 4308102Abstract: 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.
