Abstract
A coke oven door, which is positioned within a door frame in a closed position, has inner and outer sealing strips which contact the door frame. The two sealing strips jointly form a gas guide duct with the door frame. The inner sealing strip forms an elastic and flexible seal which prevents solids from passing into the guide duct but which allows gas to pass thereto. The outer sealing strip forms a gas-tight nonflexible seal.
