ABSTRACT:
An elbow cover for a coke oven ascension pipe characterized in that the opening which is covered is oval in shape and is formed at the junction of the ascension pipe and a downwardly-extending supply pipe leading to a gas-collecting main. The oval-shaped cover is provided with an immersion cup seal and a spaced sealing plate. Because of the oval shape of the opening, cleaning tools can be readily inserted into the opening to clean both the ascension pipe as well as the supply pipe.
