ABSTRACT:
An apparatus for transferring between chambers of a coke oven charging gases which develop during the charging of the chambers, while preventing the escape of the gases to the surrounding environment, includes first and second covers mounted for movement between first positions closing charging openings through an oven roof and second positions uncovering such openings. Ducts surround the peripheries of the first and second openings, such ducts being filled with a displaceable sealing medium. First and second housings form respective first and second compartments enclosing the first and second covers, respectively, at all positions thereof. The first and second covers have apron members extending into the displaceable sealing medium in the respective ducts when the covers are in the first positions thereof. The housings have at lower portions thereof seals for sealing the compartments from the exterior. First and second lifting devices are associated with the respective housing to move the first and second covers, respectively, within the respective compartments between the first and second positions of the covers. A transfer duct extends between the first and second compartments for, upon the covers being moved from the first positions thereof, transferring charging gases between the chamber openings via the compartments.
