Abstract: The invention relates to a method of reducing emissions of byproduct gas when charging oven chambers of a battery of coking ovens, on the proviso that the oven chamber (1) to be charged is opened on the machine side (MS) of the battery of coking ovens, and a block of compressed coal (10) is introduced into the opened oven chamber (1). Byproduct gases released during introduction of the block of compressed coal (10) into the hot oven chamber (1), are discharged through a byproduct-gas manifold (11) attached to the oven chamber (1) and are then preferably freed of dust and incinerated. Crude gases formed in the closed oven chambers during coking are discharged through a crude-gas manifold (3) attached to the oven chambers (1) and are passed on for treatment by at least one gas scrubber.

Abstract: A method for reducing the coking time in the oven area near the door or end wall and for improving coke quality and situation of emissions by compensating for radiation losses through coke oven chamber doors and end walls is described. This compensation is accomplished by varying the height of the coal cake in the environment of the frontal coke oven chamber doors. The variation is achieved both by increasing or decreasing the coal cake over part of the length or over the entire length of the coke oven chamber door. 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.

Abstract: Improvement in carbonization in a carbonization furnace and simultaneous reduction in NOx emissions is achieved by recirculation of waste gas from a coking oven back to the oven chamber, the downcomers, or the sole channel system.

Abstract: Disclosed is a method and device for charging the chambers of a coke oven with compacted coal. The method includes placing a plurality of adhesion reduction particles onto a coke oven charging plate, the particles being configured to reduce at least one of adhesion forces and friction forces present between the charging plate and compacted coal to be loaded thereon, loading compacted coal onto the charging plate, moving the charging plate loaded with compacted coal to the coke oven chamber, and slidably removing the compacted coal from the charging plate such that the compacted coal is disposed in the coke oven chamber. The device comprises a metal plate configured to load compacted coal into the coke oven, a plurality of adhesion reduction particles affixed to the metal plate by an adhesive layer, and a device used to move the metal plate to a front of the firing chamber of the coke oven.

Abstract: A method for extracting flue gases from a coke oven chamber, wherein the flue gases that develop briefly during the process of discharging and charging the coke cake from and to the coke oven chamber are extracted by a vacuum generated in the headspace above the coke cake. The vacuum in the headspace above the coke oven chamber is generated via channels through the lateral walls of the coke oven chamber or in the coke cake. 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.

Abstract: A method for compensating flue gas enthalpy losses of heat-recovery coke ovens, having a coke oven bank, connected to one or more boilers by one or more a flue gas channels. 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.

Abstract: The invention relates to a method and a device for evacuating hot raw gases which occur in the oven chambers of a coke oven battery during coking. The oven gases are lead from the oven chambers into a hot gas collector. The pressure in the oven chambers is controlled by shut-off and throttling devices which are arranged in the hot gas streams between the raw gas outlet of the oven chambers and the hot gas collector. The positions of the devices are controlled according to the pressure that is measured in the allocated oven chamber. The gas of the hot gas collector is supplied to a steam boiler firing or a fission reactor.

Abstract: A heating wall of a coking oven, particularly a horizontal coking oven, separates the coking chamber of the coking oven from the heating flues through which a heating medium flows to heat a charge of coking coal which is contained in the coking chamber. The heating wall is provided with a plurality of individual compartments which are separated from each other and also from the coking chamber and from the heating flues, the compartments being situated between the coking chamber and the heating flues and increasing the rate of heat transmission through the heating wall. Depending on the desired heat-transmission properties of different portions of the heating wall, the compartments may be distributed either uniformly or nonuniformly, or may have the same or different dimensions. The heating wall is constituted by refractory blocks and the enclosed compartments are provided in these refractory blocks.
