Definitions

  • the invention relates to a battery of coke ovens and to a method for repairing old batteries.
  • the coke oven batteries consist (see in cross section in Figure 1) of a central part 1 of coal distillation, a front part 2 or machinery and a rear part 3 of coke outlet.
  • the central part 1 essentially consists of a brick structure produced on a base 4 and comprising at 5 a regenerator and at 7 an alternating arrangement, in the longitudinal direction, of oven cells 8 and sides 9 (see FIG. 2) .
  • the oven cells 8 are intended to contain the coal to be distilled and have upper orifices 10 for loading the cells into coal via the hoppers 11 of a charging machine 12 (in the case of charging by gravity).
  • the sides 9 are divided from the front of the battery and towards the rear by a succession of spacers 13 delimiting flues 14 supplied with air and gas so that the heat released by the combustion of the gas produces the distillation of the harden adjacent 8 oven cells.
  • the front part 2 consists of an unloader 15, movable longitudinally to the battery of ovens on rails 15 1 , this unloader being provided with a ram 15 2 , movable in the direction of the arrow F, in order to penetrate by the front port 8 2 of the opposite oven cell for pushing the coke salmon out of this cell through the rear port 8 1 .
  • the movement of the unloader 15 on the rails 15 1 therefore makes it possible to place the ram 15 2 opposite the various furnace cells to unload them after distillation of the coal.
  • This front part 2 also comprises, as shown in FIG. 1, a collector 16 of the gas produced during the distillation of the coal, this gas being brought to this collector by a riser 16 1 and a barrel 16 2 .
  • the rear part of the coke oven battery comprises a coke guide 17 movable longitudinally on rails 17 1 in order to be placed in front of the rear orifice 8 1 of the oven cell 8 to be unloaded, and a coke wagon 18, movable longitudinally to the battery on rails 18 1 so that, when an oven cell 8 is discharged by the ram 15 2 , the coke salmon is deposited in a layer of uniform thickness on the coke wagon 18 which is moves in synchronism with the fall of the coke.
  • This rear part 3 also includes a coke dock 19 on which is poured the coke from wagon 18 for cooling after extinction.
  • the flues 14 of the corners are supplied with air and gas in alternating cycles, the air supply being effected by means of the cells of the regenerator so that the air supplying half of the flues is heated by the cells of the regenerator which were, in the previous cycle, heated by the fumes resulting from the combustion of the gas.
  • the pedestals 9, alternated with the oven cells 8, are produced according to a construction method which is shown in FIG. 2 in horizontal section along A-A in FIG. 1 and in FIG. 3 in perspective.
  • the pedestals 9, separating the oven cells 8, are made by a brick construction surrounded by a vertical metal frame 21, while the rear ends 8 1 of the cells 8 are closed by doors 22 which are open during the feeding of the salmon of coke.
  • This construction of the piers consists of superimposed beds of bricks 23 1 , 23 2 , 23 3 , etc ... which, to constitute the side partitions 24 separating the flues from the oven cells, each consist of panniers 25 and headers 26 , the pannieresses 25 being arranged at the height of the flues 14, while the headers 26 extend, for the same bed, one spacer out of two.
  • the two adjoining panneresses of the same bed have their joint plane situated in the middle of the end faces of the headers of the upper and lower beds, so that the joint plane 27 of two contiguous panes of a bed is located vertically in the middle of the width of the end faces of the two headers 26 of the lower and upper beds (see Figures 3).
  • the batteries of known coke ovens often exhibit, after a few years of operation, damage to the walls 24, whether on the rear side (coke side) or on the front side (machine side), these damage being established over a period of time. length corresponding to several flues 14.
  • the intervention that is required is more important on the coke side than on the machine side because of the abrasion effect of the coke during its discharge and the heating of the metal parts which it causes.
  • the repairs include that of the roof, we also demolish the vaults and cover corresponding to the sidewalls to be repaired, otherwise we proceed, before the demolition of the flues, to support the vaults or to suspend them.
  • the first method it is necessary to fit, at the rate of one seat out of two, cold new panneressses between hot old headers and, for example by supposing that the repair is carried out up to line 29 in FIG. 3, it is necessary to fit new and cold panniers 25 1 between old and hot headers 26 1 .
  • each embedded brick should expand on itself by compressing the binder without its expansion reacting on the new brick above it.
  • the walls 24 are cut along a vertical plane 30, perpendicular to the wall and from top to bottom of the walls, this vertical plane passing through the middle of the headers 26 2 of this plane .
  • This second method however has significant drawbacks and in particular sawing the pedestal is not without shaking the assembly which is a complex assembly of bricks linked together by sorts of tenons and mortises.
  • this second method leads to weakening the headers 26 2 whose width is reduced by half at the height of the joint plane 30, while it is very difficult to obtain a vertical sliding joint which is tight and to avoid consequently the leakage of gas towards the flue or smoke towards the cell, which again leads to the rapid deterioration of the walls and the need for important and delicate follow-up maintenance.
  • British patent n ° 2.050.586 describes a repair process consisting in sawing the damaged part vertically at right from one of the side faces of the headers; the adjacent pannieresses are therefore cut along the joint plane, and the preserved pannieresse part is assembled with a repair brick provided with an internal covering tab.
  • the object of the present invention is in particular to remedy these drawbacks and to this end relates to a battery of coke ovens comprising a brick structure assembled by a binder and placed above a regenerator.
  • this structure delimiting, in the longitudinal direction of the battery, an alternating succession of furnace cells containing the coal to be distilled and legs supplied with air and gas so that the heat released by the combustion of the gas ensures the coking of the coal introduced into the cells, the cells (or ovens) being provided at their upper end with holes for loading the cells in distilled coal, at their rear end with an orifice for discharging the coke to a coke guide and a coke wagon and at their front end of an orifice for the passage of a ram for the discharge of coke salmon through the rear orifice, each pedestal being divided internally and vertically into flues by spacers, while the walls of the pedestals also constituting the walls of the adjacent oven cells consist of a stack of horizontal bricks beds fitted with tenons and mortises, each bed comprising
  • a vertical joint plane established along a vertical alignment of one of the lateral faces of the headers, the two adjoining panneresses of the beds higher and lower than those containing these headers being one elongated, the other shortened by so that their joining joint is in said vertical joint plane.
  • the assembly plane being in the vertical plane is a flat joint assembly with grooves and vertical intermediate ion.
  • the rod of the ioint flat assembly is rectilinear and constituted by an element independent of the purlins and headers and is housed, with the interposition of a binder, in vertical grooves formed in the faces of the ends of these panneresses and the lateral faces of these headers, opposite.
  • the rod consists of elements made of refractory material (silica or silico-aluminous), the length of which is greater than the thickness of a bed of panniers and headers.
  • the vertical ioint plane is established at the height of the second strut of the counters counted from the front and / or rear ends of these pedestals.
  • the object of the present invention is therefore the production of a new coke oven battery or the repair of old batteries which make it possible to avoid, or at least to reduce significantly, the harmful effects resulting from temperature variations and which result in the deterioration of ovens (cracking of joints or bricks, stripping of joints, etc ).
  • the present invention also makes it possible to use materials of a different nature having different characteristics, in particular relating to resistance to thermal shock or resistance to high temperatures, so as to increase the reliability of the construction.
  • the present invention makes it possible to facilitate the construction and repair of oven batteries, as well as to maintain a tight seal at the height of the parts of ovens subjected to different temperature conditions and therefore capable of moving relative to one another. to the other.
  • FIGS. 6 and 7 one of the legs 9 of a battery of coke ovens according to the invention is shown, these legs being alternated with the oven cells 8, as shown in FIG. 2.
  • These legs are divided from front to back, by the spacers 31 delimiting the flues 32, the side walls 33 of these legs, which also constitute the walls of the adjacent oven cells 8, being produced by a vertical stacking of beds horizontal 34 1 , 34 2 , 34 3 each made using panniers 35 and headers 36 assembled by a binder.
  • two consecutive struts 36 are separated by two adjoining panniers, while from each bed with adjacent lower and upper beds, the junction plane 38 of two contiguous panniers is located in the middle of the end face of the struts of the beds upper and lower adjacent.
  • this construction is modified near one or both ends of the sides, so as to establish a joint plane which in the example shown is located in a vertical plane 39.
  • the panneresses 35 1, arranged opposite this plane 39 with respect to the adjacent end of the pedestal, have a length such that one of their faces ends is located in this joint plane 39.
  • the facing pannieresses 352 which are situated on the side of the adjacent end of the pedestal with respect to this plane 39, are shortened by a corresponding length so that one of their end faces is also located in this plan 39.
  • This plane 39 is thus, in the example shown, situated at the height of a vertical alignment of a lateral face of the struts 36 and of the side of the lateral edge of these struts which is directed towards the end of the pedestal, as is note on figures 6 and 7.
  • the joint plane 39 could also be located, if desired, at 39 1 on the opposite side of the headers 36.
  • a rod 41 of this assembly 40 is rectilinear and constituted by an independent element, in the example of square section.
  • This rod 41 is housed with the interposition of a binder 42, in recesses 43 of corresponding shape, with a V-profile in the embodiment illustrated in FIG. 8, which are formed vertically opposite one another in the end faces of the panneresses or the lateral faces of the headers and thus determining vertical grooves.
  • This rod, as well as the recesses may be of various geometric shapes.
  • these rods 41 are of a length greater than the thickness of a bed 34 1 , 34 2 , 34 3 , etc., that is to say greater than l '' thickness of a pannier or a header and are arranged so that a rod 41, located at the height of a bed, protrudes by its ends in the adjacent upper and lower beds and preferably on half the height of these adjacent beds.
  • the length of a rod is therefore equal to twice the thickness of each bed.
  • this joint plane 39 is preferably made at the height of the second spacer 31 counted from the adjacent end of the pedestal.
  • this joint plane 39 is disposed between the zones which, during the operation of the battery, are subjected to different temperature conditions resulting for example from the greater action of the temperature of the ambient air on the ends of the walls or more significant cooling of the ends of the walls when the adjacent oven cells are discharged.
  • the inner part of the pedestal relative to the joint plane 39 can be made using a siliceous material which is resistant to high temperatures but less well thermal shock when, on the contrary, the part of the pedestal located towards its end relative to this plane 39 will be made using a resistant material less well at high temperatures but better at thermal shocks (silico-aluminous or other).
  • the headers 36 may include stops 44 for positioning the shortest panniers 35 2 coming s 'apply against them.
  • each affected pedestal is demolished up to the vertical plane 39 to be produced, that is to say just upstream of a spacer relative to the adjacent end of the oven.
  • panniers 35 1 are put in place of existing panners, these panners being dimensioned so that their end face directed towards the end of the pedestal is located at the height of this plane 39, that is to say in the extension of the lateral faces of the headers constituting the adjacent upper and lower beds.
  • a corresponding V-shaped groove is cut in the lateral face of the headers so that this set of headers and pannieresses presents towards the outside of the furnace and therefore towards the part to be reconstructed, a vertical plane face, perpendicular to the wall and in which there is a groove, for example V-shaped, constituting an assembly groove with which the new part to be constructed will cooperate with the old part.
  • the end faces of the yes panneresses are located at the height of this vertical ioint plane are also provided with a groove whether they are normal panneresses or shortened panneresses 352 adj a-centes of the upper and lower beds.
  • the ionc 41 is put in place with the interposition of a binder so that this ioint allows free vertical expansion of the new part with respect to the old part without stresses being exerted on each other and while maintaining the tightness of assembly between these two narties.
  • each purlin 35 1 will be arranged a shortened purlin 35 (35 2 ) to then reconstitute the normal apparatus of the flues, as described above.
