Abstract:
1. A method for the production of coke comprising the steps of: using a coke oven of horizontal construction comprising at least one coking chamber, at least one primary combustion air inlet leading into the coking chamber, laterally arranged vertical downcomers as well as bottom flues with flue gas channels arranged horizontally and underneath the coking chamber for indirect reheating of the coking chamber and air feeder mains provided in the foundation for conducting air into the flue gas channels, and; coking coal in the coking chamber by disposing a coal charge onto the oven floor and by conducting primary combustion air into the coking chamber, an oven free space is in the operation of the coke oven not destined for being filled with a charge of coal or other solid feed material for coking; and discharging the gases developing during the coal carbonization through the vertical downcomers which extend in the oven walls from the oven free space of the oven room to the horizontal flue gas channels; and conducting secondary combustion air into the air feeder mains for conducting air into the flue gas channel inlets provided in the oven foundation underneath the oven floor; wherein, gas space dividing walls are arranged in the oven free space of the coking chamber vertically and parallel to each other, and by the gas space dividing walls a section-wise gas routing of the coking gas is achieved so that the gas routing is improved and a homogenization of radiation in the coking chamber is achieved, and at least one primary combustion air inlet directs primary air into each of these sections, and one or two downcomers lead out from each of these sections, so that the gas routing is adapted to the positioning of the gas space dividing walls.
