Refractory oven doors and refractory oven door framing walls of a coke oven battery

A method for sealing-off a coke oven which is charged or prepared for coal carbonization through a horizontally directed front-side or rear-side oven opening, the coke oven comprising a coke oven chamber door and a coke oven chamber wall;

• wherein
• at least one opening is provided with the door device which is to be opened for charging or preparing the coke oven and which is to be closed again after charging,
• the door is inserted into a vertical wall which seals-off horizontally directed oven walls to the exterior, wherein this door is moved away from the wall to open it,
• the doors are provided with a suitable framing device and a suitable mechanism for opening and closing, and
• the door-side coke oven chamber opening is sealed by combination of a rigid coke oven chamber wall and a mobile or removable door body fabricated as a plug and framed by the coke oven chamber wall, and wherein these doors exactly fit on closing into the coke oven opening, wherein
• the major part or the whole part of the coke oven chamber wall embracing the door is located above the coke oven chamber door,
• the method comprising:
• moving the coke oven chamber door out from and into the door-side coke oven chamber opening so that the coke oven chamber opens and closes, with the coke oven chamber opening having the same cross-section as the coke oven chamber door, and
• situating the bottom edge of the part of the door-embracing coke oven chamber wall located above the coke oven chamber door above the top edge of the coke cake.
