Abstract: A method for compacting coal in a manner suitable for coke oven chambers is described. The coal is initially compressed by means of a suitable compressing device into one or more coal cakes, and the obtained coal cakes are divided into compacted products by a cutting device. The compacted products are stacked on top of the each other such that they can be loaded into a coke oven chamber for coking. The compacted products enable the coke oven chambers to be loaded in a precise and a coal loss-free manner. The coal compacted products are easy to store.

Abstract: 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 oven wall embracing the oven door can also be made of a refractory material containing silica or of a material containing silica and aluminum oxides.

The vacuum is generated in the secondary heating chamber and, by way of example, can be extracted again from a vacuum supply tank which, for the time that the coke oven chamber doors are open, is connected to the secondary heating chamber by opening shut-off devices in the connecting line. The method avoids the undesirable emission of flue gases into the atmosphere. A device whereby the method can be carried out is also disclosed.

The operation of the coke oven chambers is periodically interrupted, during which time the coke cake is removed, and the individual coke oven chambers are kept hot during the interruption of the operation by an an externally fired additional burner providing hot flue gas. The resulting heat flow remains the same in comparison to the normal operation. In this way, the boilers, which are typically used to produce steam, can be operated economically.
