Definitions

  • the invention relates to a coke oven chamber door with a heat-resistant stopper, which consists of an outer door body plate and inner steel plates which are slidably arranged for thermal insulation at one end.
  • a heat-resistant stopper which consists of an outer door body plate and inner steel plates which are slidably arranged for thermal insulation at one end.
  • Such furnace chamber doors are used in particular for coke ovens, the furnace chamber walls of which are provided with heating trains which, compared to the design in flame furnaces with quenched furnace filling and moved back first heating trains, have heating trains moved forward and a mechanical leveling of the furnace filling.
  • the refractory stopper not only serves to reduce the heat emission of the door plate, which is usually made of cast iron, to the extent that the door body constructions cannot bend, but the stopper is also intended to withstand the preheating stress caused by the laying of the first heating cables Reduce the furnace, namely the furnace heads and in particular the anchor positions located there, by keeping the glowing coke furnace far back.
  • the stopper is made of refractory material, e.g. B. in the form of a resting on a lower stone holder and held by lateral stone holders, or made of molded blocks that are screwed to the door body plate, for example.
  • the first heating draft of the chamber walls is usually behind an outward-facing wall made of preferably semi-acidic stones, the outside of which is supported on the anchor stands by a layer of heat-insulating material and carries the usually interchangeable door frame.
  • the inside of the refractory stopper material protrudes into the furnace chamber up to the first heating draft.
  • the sealing joint is removed from the heat of the first heating train and the coke cake.
  • the thermal expansion of the coating that occurs during the coking process can be compensated for by using metal plates as the coating. In this way, the footprint of the door plug becomes a heating surface and can result in a better cooking of the head parts of the stove.
  • An air or gas cushion can be formed between the door plugs and the steel plates.
  • the poor thermal conductivity of this closed air or gas space can be used excellently for thermal insulation.
  • the distance between the door body and steel plates can be varied depending on the permissible surface temperature of the door body.
  • the steel plates are stiffened in a T-shape and are located one above the other at the ends. The steel plates can freely expand at these ends.
  • the steel plates should not be longer than 1 m in the case of 4 m high furnaces, the steel plate length decreasing by one tenth of the change in height with each increase in the furnace height. For a 7 m furnace, this would result in a maximum length of steel plates of 0.7 m.
  • the operational availability of this door system is much lower than with conventional door plugs due to recurring faults. The damage is concentrated on the lower plate area.
  • the invention has for its object to adapt such door plugs to the rough coking plant.
  • the invention is based on the idea that the cause of the various damage is the fact that when the door is pulled off - in particular in the manually controlled sequence - the doors are partially pulled off and subsequently lowered, so that the bottom steel plate rests on the sole touches down. At this point, the entire weight rests on the steel plate, which is then strongly deformed together with its holder. In the further work process, the door is pulled forward, the lowest steel plate then slides over the sole and comes in front of the door frame, which is higher than the sole. As a result, the bottom plate is bent forward and torn out of the holder.
  • the lowest steel plate has a fixed point at the lower end and is slidably mounted at the upper end for thermal expansion.
  • Another advantage is the double function of the upper bracket for the lowest steel plate. According to the original concept, this bracket forms a longitudinally movable bearing for the steel plate above. According to the invention, this bracket also forms a longitudinally displaceable bearing for the lowest steel plate.
  • a common movable bearing is provided for two adjacent steel plates.
  • the ends of the steel plates facing away from the displaceable mounting have common holders with the adjoining steel plates, so that two steel plates are locked to each of these holders.
  • the top steel plate of the oven door is possibly using separate brackets and Slidable bearings arranged so that the steel plate end located at the top of the door is locked and the thermal expansion of the steel plate or the associated change in length affects down. All steel plates are arranged so that the lower end of each upper steel plate overlaps the upper end of an underlying steel plate.
  • the known coke oven chamber door is provided with a door body 1.
  • a plug 2 is located on the door body 1.
  • the coke oven chamber door closes an interchangeable door frame of a coke oven.
  • the interchangeable door frame usually sits in the top of the coke oven chamber walls, which are equipped with heating cables.
  • the coke oven chamber door projects with the stopper 2 into the coke oven chamber, while the door head 1 lies against the outside of the door frame.
  • sealing strips not shown, provide an adequate seal.
  • the sealing strips consist, for example, of profiled iron.
  • the stopper 2 forms a hollow body and, as a hollow body, a gas collecting space through which the gas resulting from the coking can rise to a gas collecting space arranged in the head of the coke oven or to a riser pipe in the ceiling area of the coke oven.
  • the plug 2 is composed of a number of sections, of which the sections 3 and 4 are shown in FIGS. 1 and 2. Each section 3 and 4 has a steel plate 5. The individual steel plates 5 overlap, from top to bottom so that the lower end of an upper steel plate 5 overlaps the upper end of a subsequent lower steel plate 5.
  • the steel plates 5 are provided with tabs at each end.
  • the tabs on the upper steel sheet end serve to lock the associated steel sheet end, while the tabs on the lower steel sheet end are intended to enable longitudinally displaceable storage for thermal expansion of the sheets downwards.
  • the tab of section 4 at the lower end of sheet steel is designated by 6, that at the upper end of section 3 by 7 and that at the lower end of section 3 by 8.
  • the tab 6 is guided with bolts 9 in the tab 7 so as to be longitudinally displaceable. For this purpose, there is a sufficient section for the thermal expansion of the steel sheet 5 of section 4 between the tabs 6 and 7.
  • the tab 7 is in turn on a bracket 10 attached to the door body 1. Between the bracket 10 and the tab 7 there is a schematically indicated bolt or screw connection which defines the upper end of section 3. The same arrangement exists at the upper end of section 4. At the lower end of section 3, a bracket 11 enables longitudinally displaceable storage for thermal expansion. The bracket 11 is fastened to the door frame and guides the lower end of the section 3 with a bolt 12 which is displaceable longitudinally in the bracket 8.
  • the cavity existing between the steel plates 5 and the door body 1 forms a vertical gas collection space, via which the gaseous coking products are advantageously derived and fed to the upper gas collection tube and the riser tube. Due to the resulting favorable gas pressure conditions, the pressure structure on the door frame or on the coke oven door as a whole is so favorable to the respective outer atmosphere that emissions on the coke oven doors are prevented with conventional sealing strips.
  • the steel plates 5 have a high thermal conductivity.
  • the high thermal conductivity also results in the supply of heat via the steel plates 5. This effect allows the plate to protrude less than 100 mm into the furnace chamber. This is equivalent to an increase in the usable oven volume while the head sections are cooked consistently.
  • the coke oven chamber door according to FIGS. 4 to 7 differs from the coke oven chamber door according to FIGS. 1 to 3 both by a different suspension of the sections 3 and 4 in the connecting area 13 and by a different arrangement at the foot of the plug 2.
  • the latter area is marked with 14.
  • the tab 7 is provided at the connection point with the bracket 10 with an elongated hole 15, which enables a thermal expansion of the steel plate 5 in the longitudinal direction of the door within the scope of section 3.
  • the connection between the tab 7 and the bracket 10 is made by a bolt arranged in the bracket 10 and shown schematically, which slides in the slot 15.
  • the console 16 extends essentially to the steel plate 5 of section 3 and is connected to a slide shoe 17 on the underside.
  • section 3 is stiffened with the bracket 16 and is additionally protected against damage by the sliding shoe 17. In this way it is achieved that neither damage to the door structure nor to the frame or the sole stones can occur when inserting the door, regardless of the operation of the door operating machines.
