Definitions

  • the invention relates to a method and a device for the hot repair of the heating trains of a coke oven battery.
  • the heating cables to be repaired or renewed are sealed off from the remaining, still hot parts of the coke oven by partition walls (so-called mirrors) provided with a fire-resistant coating. While the heating of the heating cables to be repaired is switched off, the remaining heating cables continue to be heated. So far, the heating trains to be repaired or renewed were initially bricked up completely from the sole of the coke oven to the ceiling. Only after this work had been completed was the new masonry heated by specially made openings in the partition walls with warm air from the non-renewed hot part of the coke oven and possibly also with additional flue gas. This means that in this phase, residual heat is transferred from the heated heating elements to the freshly bricked heating elements by convection. For the heating required after heating, the new heating trains had to be connected again to the regenerative heating system of the coke oven.
  • the invention is therefore based on the object of improving the method for hot repair of the heating trains of a coke oven battery in such a way that the disadvantages described above are avoided, the use of the improved method should also be possible in particular in coke ovens whose chamber height is more than 5 m.
  • the method used to achieve this object is characterized in that, even while the heating cables are bricked up, the sections of the respective heating cable that have already been completed are heated to a temperature of approximately 250 ° C. and the new heating cables up to immediately after completion of the masonry work a temperature of about 500 ° C are heated, the heating and heating being carried out by means of a gaseous heat transfer ore which is blown into the heating trains and which has been appropriately heated in a heat exchanger using the heat of the hot parts of the coke oven battery.
  • the method according to the invention in contrast to the previously customary method of operation, already sees heating during the building of the walls of the heating cables in front. It is appropriate that the already finished sections of the respective heating flue are closed at the top by a cover plate provided with a refractory coating, in the middle of which an opening with a pipe-like chimney, for example, is arranged.
  • the gaseous heat transfer medium is blown into the space below the cover plate and in this way heats up the sections of the respective heating train that have already been finished.
  • the correspondingly cooled heat transfer medium can then escape through the chimney located in the cover plate without impairing the masonry work carried out above the cover plate.
  • the cover plate With the progress of the masonry work, the cover plate is removed from its previous position and set correspondingly higher, so that the freshly bricked parts of the heating train underneath can be heated accordingly. This means that the position of the cover plate is gradually shifted from bottom to top while the heating train is bricked up.
  • the cover plate also serves as a stone protection and mortar collecting plate, so that the underlying, freshly bricked parts of the heating train cannot be damaged by falling stone rubble or mortar.
  • the cover plate is removed and the freshly bricked heating cable is heated to the desired temperature of approx. 500 ° C.
  • Compressed air can preferably be used as the gaseous heat transfer medium for heating and heating.
  • a different gas for this purpose such as flue gas or nitrogen, if this should be appropriate for certain reasons, such as when heating the heater.
  • the heating of the gaseous heat transfer medium required for the implementation of the method according to the invention takes place in indirect heat exchange with the hot parts of the coke oven battery, although there are of course different possibilities for this, which will be discussed in more detail below, for example.
  • the design of the heat exchanger used for this purpose is primarily aimed according to the local conditions in the part of the coke oven battery in which the heat exchanger is to be installed, and according to the design features of the respective coke oven battery.
  • the heat exchanger is preferably designed in the form of a tube coil which consists of one or more turns which are bent in the shape of a hairpin.
  • the inlet opening for the gaseous heat transfer medium lies at the cold end of the heat exchanger, the heat transfer medium flowing through the heat exchanger and then being fed to the heating train to be repaired at a correspondingly increased temperature.
  • This temperature can be controlled in a manner known per se by regulating the flow rate of the heat transfer medium per unit of time. Fittings such as valves, slides and / or perforated disks are provided for this purpose, which are preferably arranged at the cold end of the heat exchanger
  • One way of heating the gaseous heat transfer medium is, for example, that the heat exchanger, which in this case is designed as a hairpin-shaped tube coil, is arranged on the upper edge of the regenerator associated with the heating train to be repaired.
  • the heat transfer medium is heated accordingly as the heat emitted by the regenerator flows through the pipe coil and is then blown into the connecting channel between the regenerator and the heating train to be repaired at the hot end of the pipe coil.
  • the heat transfer medium then reaches the heating train via this connecting channel, in which it is used, as described above.
  • This method requires a separate coil for each heater train to be repaired.
  • the hairpin-shaped tube coil serving as the heat exchanger is not arranged on the regenerator but on the sole of the furnace chamber, which lies next to the heating train to be repaired.
  • the heating cables to be repaired will still be called the others Heating trains separated by a partition arranged inside the furnace chamber and provided with a fire-resistant coating.
  • This partition wall has through openings for the coil at its lower end so that it can extend into the hot part of the furnace chamber. The heat required to heat the heat transfer medium is therefore provided by the hot part of the furnace chamber.
  • Fig. 1 shows the furnace chamber 1 with the two opposite heating trains 2 and 3.
  • the left heating train 2 is to be subjected to a hot repair.
  • the pipe coil 5 serving as a heat exchanger is arranged on the upper edge of the regenerator 4 belonging to this heating train, which is on the outside of the regenerator lying inlet opening is pressurized with compressed air.
  • the outlet opening 6 of the coil 5 opens into the connecting channel 7, which connects the regenerator 4 with the heating cable 2.
  • the compressed air correspondingly heated in the coil 5 therefore passes from the connecting duct 7 into the heating duct 2.
  • the required sealing between the outlet opening 6 and the connecting duct 7 is achieved via the plate 9, which is made of VA steel and is provided with a refractory coating
  • the repair work in the lower section of the same should already be completed in the present case.
  • the cover plate 10 which separates the part that has already been repaired from the part of the heating element 2 that has not yet been repaired.
  • the heated compressed air blown into the heating cable 2 cannot therefore reach the upper part of the heating cable unhindered. Rather, this compressed air serves to heat the part of the heating train which is already finished and which is located below the cover plate 10.
  • the correspondingly cooled compressed air can then escape via the chimney 11 located in the cover plate 10 without the wall work above the cover plate 10 being impaired as a result.
  • the position of the cover plate 10 is gradually shifted upward, so that the sections of the heating cable 2 that have already been completed can each be heated to approximately 250 ° C., although the heating cable repair has not yet been completed.
  • the cover plate 10 is removed and the temperature of the compressed air supplied is increased so that the heating cable is heated to a temperature of approximately 500 ° C.
  • a configuration of the pipe coil 5 that is particularly suitable for this purpose will be discussed further below in connection with FIG. 3.
  • the reference number 12 denotes the transition to the adjacent heating train.
  • the structure of the heating element 3 corresponds in principle to the structure of the heating element 2, so that there is no need to go into details again here.
  • the coil 5 is arranged on the bottom of the furnace chamber 1.
  • the front heating cables 13, 14 and 15 in the area of the heating cable head are to be repaired at the same time.
  • the rear, hot part of the furnace chamber 1 is therefore separated from the front part by the partition 16, which is provided with a refractory coating 17.
  • the partition 16 has at its lower end through openings for the coil 5, so that it can penetrate into the hot part.
  • the compressed air blown into the coil 5 via the inlet opening 18 is therefore correspondingly heated in the hot rear part of the furnace chamber 1.
  • the stub lines 19, 20 and 21 are arranged through which the heated compressed air can enter the heating cables 13, 14 and 15 to be repaired.
  • the bypass lines 22, 23 and 24 are connected to the stub lines 19, 20 and 21, through which cold compressed air can be blown from the coil 5 for temperature regulation into the stub lines 19, 20 and 21.
  • the valves 25, 26 and 27 serve to regulate the compressed air supply through the bypass lines 22, 23 and 24.
  • the compressed air supply in the coil 5 can also be controlled by the slide 28.
  • the valves 25, 26 and 27 and the slide 28 are controlled via thermocouples depending on the desired temperature.
  • the figure in FIG. 2 also shows the anchor stand 29 with the associated spring elements 30 and the wall protection plate 8.
  • the tube coil 5 serving as a heat exchanger.
  • the tube coil 5 serving as a heat exchanger.
  • the heat transfer medium used is used open valve 32 introduced into the coil 5 via the connection 31. Since the valve 34 remains closed, by the heat transfer medium flows only the pipe section A and then passes through the outlet opening 6 into the heating train, not shown in the figure.
  • the valve 32 is closed and the valve 34 is opened, so that the heat transfer medium initially enters the pipe section B via the connection 33 and both the pipe section B and subsequently flows through the pipe section A. Because of the longer flow path associated therewith, there is of course a greater heating of the heat carrier in the coil 5, so that it has the higher temperature required for heating the heating train.
