This invention is directed to an extremely lightweight construction for coke oven doors with simultaneous optimal sealing, by assuring that the oven door comprises of one sealing unit and the closing forces act simultaneously on the seal, thereby avoiding heat loss between the two units as much as possible.

Coke oven doors for horizontal-chamber coke ovens

This invention is directed to an extremely lightweight construction for coke oven doors with simultaneous optimal sealing, by assuring that the oven door comprises one sealing unit and the closing forces act simultaneously on the seal, thereby avoiding heat loss between the two units as much as possible.

This invention is directed to an extremely lightweight construction for coke oven doors made to provide optimal sealing; the oven door comprises one sealing unit having a seal, and closing forces are applied to act uniformally on the seal, thereby minimizing heat loss between the sealing unit and the coke oven as much as possible. The oven door, on its outside surface, is also provided with a boxed duct structure which in use is vertical and has an open top; the boxed structure facilitates heat dissipation by the door outside surface, by convection air flow in the boxed structure.
