Definitions
- the invention relates to a method for filling a horizontal chamber coke oven.
- Coal filling trucks are used to fill the furnace chambers of a horizontal chamber coke oven, which run along the furnace ceiling and have discharge devices with screw conveyors and filling telescopes.
- the filling telescopes are lowered onto filling openings in the furnace ceiling to fill a furnace chamber.
- the coal reaches the furnace chamber through the filling telescopes and the filling openings, whereby pronounced cones of bulk form below the filling openings.
- the pouring cones are leveled with the help of a leveling rod that is inserted into the furnace chamber through a side door.
- the leveling of the bulk material surface is intended to ensure that filling gases, which develop to a large extent towards the end of the filling process, flow out of the furnace space of a discharge opening and can be discharged into a template.
- the leveling of the bulk material surface is not without disadvantages.
- the gas collecting space above the surface of the bulk material is reduced by the leveling rod during pianing. This means that the gas extraction deteriorates, so that emissions can occur more intensely in this phase.
- the leveling process also increases the cycle times, since the coal filling truck and the leveling device work in a close connection, so that the coal filling truck lasts waits at the furnace chamber to be filled until the leveling process is finished.
- the invention has for its object to provide a method for filling a horizontal chamber coke oven, in which there are no cones obstructing the gas discharge below the filling openings, so that a leveling process can be omitted.
- centrifugal cells are introduced into the furnace chamber which have a discharge element rotating about a vertical axis and in that the bulk material is fed onto the centrifugal cells which distribute the bulk material in the furnace chamber by rotating their discharge element.
- centrifugal cells are understood to mean devices which are charged with coal from above when the furnace chamber is being filled and which have rotatingly driven application elements which, due to their rotational movement, throw off the coal. Scattering plates and / or throwing blades can be used as discharge elements.
- a horizontal chamber coke oven has narrow and elongated oven chambers.
- centrifugal cells with lateral guide plates are used which limit the outlet area.
- the centrifugal cells can be designed in such a way that the carbon particles emerge from the centrifugal cells in one direction with flat, extensive trajectories, while the trajectories in the transverse direction are limited to a close range by the guide plates.
- the centrifugal cells are introduced into the furnace chamber through filling openings in the furnace ceiling before the furnace is filled, and are pulled out through the filling openings after the furnace has been filled.
- the filling process and the trajectory of the carbon particles can be changed by the design of the discharge elements and also by varying their speed.
- An advantageous embodiment of the method according to the invention provides that the speed of the discharge elements is controlled during the filling process and the trajectory of the bulk material thrown off by the centrifugal cells is changed so that the bulk material surface is as uniform as possible.
- the speed of the discharge elements is expediently increased with increasing furnace filling, so that to the extent that the bed height increases during the filling process, flatter trajectories of the carbon particles are established.
- FIG. 1 shows a section through an oven chamber of a horizontal chamber coke oven during a filling with coal
- Fig. 2 is a centrifugal cell used for filling.
- the furnace chamber of a horizontal chamber coke oven 1 shown in FIG. 1 has an oven ceiling 2 which contains closable filling openings 3. Coal enters the furnace chamber through filling telescopes 4, which are lowered onto the opened filling openings 3.
- a discharge device 5 for filling gases is also arranged.
- centrifugal cells 6 are introduced into the furnace chamber through the filling openings 3 or other openings in the furnace ceiling 2, which have a discharge element 7 driven in rotation about a vertical axis.
- the bulk material fed through the filling telescopes 4 is fed onto the centrifugal cells 6, which distribute the bulk material in the furnace chamber by rotating its discharge element 7.
- the filling process and the trajectory of the carbon particles can be changed by the design of the discharge elements 7 and by the variation of their speed.
- Fig. 1 trajectories 8 are shown schematically for different speeds.
- the speed of the discharge elements 7 can be controlled during the filling process in order to change the trajectory of the bulk material thrown off by the centrifugal cells 6 in such a way that the bulk material surface 9 is as uniform as possible.
- the speed of the discharge elements 7 is expediently increased with increasing furnace filling, so that flatter trajectories 8 of the carbon particles are obtained.
- centrifugal cells 6 are understood to be devices which are charged with coal from above when the furnace chamber is filled, and a rotating one Have discharge element 7, which throws off the carbon particles. Scattering plates and / or throwing blades can be used as discharge elements 7. 2 shows the basic structure of a centrifugal cell 6 suitable for the method described.
- discharge element 7 it has a rotor with throwing blades 10 which can be driven in rotation about a vertical axis.
- lateral guide plates 11 are provided in the exemplary embodiment, which limit the throwing angle.
- the rotor is driven by a motor (not shown), which is connected to the discharge element 7, for example, by a coupling shaft brought up to the furnace chamber.
- the furnace chambers of a horizontal chamber coke oven can be filled in such a way that no disruptive cones of material arise which hinder the discharge of filling gases from the furnace chamber. According to the invention, there is no need for a leveling operation on the bulk material surface.
