摘要

"Coke oven battery" A coke oven battery has horizontal coking chambers and a roof. Vertical conduits extend through the roof. In order to prevent leakage of gas through the roof a gas tight screen of metal sheet is provided in the roof. The screen consists of substantially horizontal sections extending between the vertical conduits and substantially vertical sections adjacent the vertical conduits. The vertical sections have a gas-tight seal to mounded bricks at the top of the vertical conduits by casting in concrete a stepped portion of those sections and the mounded bricks.
