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

摘要

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.

主权项

1. A device 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, 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.
