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.

Abstract: A coke-oven battery has at least two chambers separated by a heating wall head and having openings provided with vertical jambs juxtaposed with the head. An upright anchor post is spaced horizontally forward from the head, and a plurality of U-shaped yokes are provided between the post and the head. Biasers bear on the anchor post and press the yokes against the jambs and thereby press the jambs against the head. A thin-walled sheet-metal head cover having upright edges is clamped between the jambs and the head and extends horizontally as a single piece between the jambs.

Abstract: The invention relates to a wall protector for a heating oven head (2) between two oven chamber openings (1, 1?) of a coke oven battery, said wall protector being laterally bounded by vertical frame elements (5, 5?). The wall protector comprises an anchor stand (4) arranged in front of the heating wall head (2), extending vertically, and pressing devices (6) fixed to said anchor stand (4). Additionally, the wall protector has U-shaped yoke elements (7) onto which pressure is exerted by the pressing devices (6), and a rectangular head cover (10) covering the heating wall head (2). According to the invention, the U-shaped yoke elements (7) fit tightly against supporting surfaces of the frame elements (5, 5?) in a force-fitted manner and the head cover (10) consists of a thin-walled metal sheet constrained between the frame elements (5, 5?) and the heating wall head (2).

Abstract: A method is provided for operating a coke oven battery including many identical coking chambers, a raw gas receiver, and throttle devices arranged in the receiver for individually controlling the gas pressure in the chambers. Each throttle device includes an immersion bucket acted upon by water. Gas lines terminating in immersion pipes in the immersion buckets connect the chambers with the receiver. Throttle devices are employed that include an overflow that can be vertically adjusted by an actuating drive for controlling the liquid level in the immersion bucket. For a coking chamber to which a pressure control device is allotted, the setting signals for the actuating drive allocated to the time pressure curve in the process of carbonizing coal to coke are recorded as a position-time curve. The actuating drives of throttle devices that are allocated to coking chambers without pressure control devices are controlled according to the position-time curve.

Abstract: According to the invention the heating system for regenerative coke oven batteries that can be heated with rich gas and/or lean gas or mixed gas is provided comprising vertical flues cooperating in pairs, each vertical flue being connected to a regenerator for preheating the air and, in the case of lean gas operation, for preheating the lean gas or mixed gas. High and low combustion stages, as well as structure defining an internal flue gas return at levels above a flue base are provided. Discharge openings are provided at at least three levels for supplying each flue. A base discharge opening is provided at the flue base directly connected to regenerators. Hollow communicating channels are defined for connecting the regenerators to discharge openings located above the flue base. The hollow communicating channels are preferably formed in each communicating wall connected to a discharge opening leading only to one adjacent flue.

Abstract: Coking system, wherein the coking blends particularly based on hard coal, are fed batchwise to a reactor (1), which is heated indirectly by heat recovery in regenerators (I, II) or recuperators, whereby the reactor is built as a high-capacity coking reactor (100), several high-capacity coking reactors are combined to form a reactor block and the high-capacity coking reactors are built as mutually independent modules, whereby each module can be operated or optionally replaced independently of the neighboring modules, with little or no impairment of the operation of the neighboring modules. The individual reactors are independently operatable in terms of statics and heat supply. The regenerators, or recuperators (I, II, R, R') can be arranged laterally or underneath the reactor chamber. Neighboring reactors can have a common intermediate wall (2). The reactor chambers have a width of at least 0.7 m, a height of at least 8.5 m and a length of at least 18 m.
