A heat-resistant door device for closing a horizontal coke oven chamber is made of a refractory material, using a material containing silica or a material containing silica and aluminum oxides, in particular. The material has a low temperature expansion coefficient and it is thermally well insulating so that the door is not deformed and/or distorted during the coal carbonization process. The door device is built of a coke oven wall mainly located above the door and embracing the door as well as of a mobile door located underneath. Thereby less cold ambient air enters into the coke oven chamber and radiation losses are minimized. The door may be comprised of an ellipsoidal bulge by which the coke can be better pushed into the coking chamber.

The reduction in the height of the coal cake can be generated by omission of coal or coal compacts, the increase in height can be accomplished by stacking of coal and pressing or adding of coal compacts, with it also being envisaged to omit the pressing cycle so as to obtain a recess with a lower coal cake density which also has less heat radiation.
