Definitions

  • the invention relates to a coke oven door for a horizontal chamber coking furnace with a door stop protruding into the furnace chamber and made of highly heat-resistant metal and connected to the door body, via which the furnace filling is kept at a distance from the door body and which forwards the gaseous coking products to the gas collecting space arranged above the furnace filling.
  • the furnace chamber walls are provided with heating trains which, compared to the design in flame ovens with slanted furnace filling and moved back first heating trains, now have pre-moved heating trains and a mechanical leveling of the furnace filling.
  • the coke oven doors closing the two narrow sides have door plugs made of refractory material, which extend approx. 400 mm into the coke oven chamber and prevent the heat losses and inadmissible temperature increases of the iron oven fittings, such as door frames, wall protection panels and door bodies themselves, and at the same time also prevent the actual oven head from being exposed to excessive heat protect.
  • These known coke oven doors have a high weight due to the door plugs made of fire-resistant material. In addition, such pressure builds up on the inside of the coke oven in the area of the sealing cutting edge that either air is drawn in or gas is forced out.
  • a coke oven door with a door plug which consists of a continuous top-to-bottom T-beam or of parts composed of parts.
  • This carrier is provided with side walls to reach a gas collection space or has supports which are intended to ensure that the gas collection space formed is kept open.
  • a corresponding gas collecting space is only created when two such double-T beams are arranged parallel to each other on the door body.
  • the aim of a coke oven door designed in this way is exclusively to reduce the gas pressure at the door seals and thus to improve the tightness of the coke oven doors.
  • the heavy construction, which does not sufficiently give in to the thermal stresses, which is also referred to as the barrier, is covered on the coke side with a heat-resistant material. Because of this insulation, it is not possible to transfer heat from the gas collecting space formed into the coal present.
  • a hollow door plug which can also be made of metal, among other things, is provided, through which the gases can be discharged in the direction of the template. These gases can penetrate through slots on the side and on the front. In order to allow at least some absorption of thermal expansion, a continuous slot is formed on the front through which the gases can penetrate at the same time. However, this slot must be kept so narrow that no coal can penetrate into the cavity and gas collecting space, which in turn does not result in sufficient elasticity for the high thermal stresses. In addition, such a construction is complex and very difficult and, moreover, can only be kept clean with considerable effort.
  • the invention has for its object to provide a sufficiently stable door stopper for a coke oven door, which ensures that a sufficiently large gas collecting space between the door frame and the furnace filling is kept open, which enables the neighboring parts of the furnace filling to be influenced thermally and in which the gas pressure at the door seals is reduced and is evened out.
  • the door stopper consists of a plate which is not insulated from the furnace filling and which is connected to the door body via individual spacers which are arranged at a distance from one another, the body itself being provided with thermal insulation on the side assigned to the plate.
  • the cavity formed between the coke-side wall of the door body, the plate and the corresponding areas of the coke oven wall itself serves as the gas collection space. It is surprising that this gas collecting space remains open during the coking process, ie over the entire cooking time, so that the gases can be sucked off and removed without hindrance.
  • the plate resting on the spacers acts as a coking plate, which absorbs heat from the gas, then from the furnace walls and from the coke itself and passes it on to the coal, and on the other hand, it is designed and arranged in such a way that it easily makes the necessary movements due to the temperature differences and can perform without being damaged.
  • the gap remaining between the edges of the plate and the walls of the coke oven is dimensioned such that coal cannot pass through it into the gas collecting space.
  • the lightweight construction which means that the entire coke oven door is light in weight and, moreover, enables simple and quick assembly and disassembly.
  • the use of a heat-resistant steel enables the heat emitted by the gas and the radiation to be passed on to the one hand, and on the other hand ensures that the plate does not change its shape or even bend when the coke oven door is removed.
  • the plate is also easy to keep clean and prevents any caking on the door body or on the door plug.
  • the door body itself is protected from the radiation of the gas and the furnace filling by the thermal insulation, whereby in a uniform load over the length of the coke oven door is advantageously ensured.
  • the gas pressure on the door seals is reduced in such a way that emissions are avoided during the cooking time.
  • the assembly of the door stopper designed according to the invention is considerably facilitated in that the spacers are T-shaped, on the flange of which the plate rests.
  • the plate is in each case on the long flange of the T-shaped spacer, and because of this advantageous design, the plate is supported up to the edge.
  • the spacers can be bent in the end areas in order to further minimize the risk of damage to the coke oven wall. A change in the volume and thus an adaptation of the gas collecting space to the respective circumstances is possible if the spacers, as proposed according to the invention, are designed to vary in length between the door body and the plate.
  • this can have reinforcing ribs on the side facing the furnace filling, so that it is possible to produce the plate itself from the thinnest possible sheet material.
  • the invention provides for the coke-side wall to be subdivided into sections, expansion joints remaining between the sections.
  • connections for feeding nitrogen are provided between the spacers and the heating walls. Via these connections, nitrogen can be introduced into gas bubbles arranged there, which then squeeze into the gap and thus ensure its sealing.
  • the invention is characterized in particular by the fact that the susceptibility to failure of the door stopper is significantly reduced by dispensing with refractory material. Due to the special design of the door plug with the front plate, a gas collection channel is formed, which is limited by the highly heat-resistant plate or by the door body itself. Semi-coke and graphite cannot form an intimate connection with the surface of the plate, so that any deposits that may arise can be easily removed from these products.
  • the high thermal conductivity of the coking plate also has the decisive advantage that the furnace filling is always fully cooked even at the top, because the heat is not only supplied from the side of the heating walls, but also from the plates, which act as additional heating surfaces.
  • the door plug On the inside of the door body 1, the door plug is arranged, which protrudes into the furnace chamber and keeps the furnace filling at a certain distance from the door body 1 while leaving a narrow gap to the heating walls.
  • a gas collecting space 7 is formed from top to bottom, through which the gas or the gaseous coking products can rise from the bottom of the furnace chamber to the riser pipe arranged in the area of the coke oven ceiling.
  • a thermal insulation 8 is attached, which protects the door body from the heat radiation of the furnace filling or the gas.
  • the foot parts of the spacers 18, 19 are embedded in or surrounded by the heat insulation 8.
  • the plate 16, via which the furnace filling is retained, is held at a certain distance from the door body 1 via these spacers 18, 19.
  • the plate 16 consists of sections 29, 30, 31, which are each connected to the spacers.
  • the plates are stiffened by reinforcing ribs 25, 26 placed on the outside.
  • the spacers 18, 19 are each connected to the door body 1. They are designed as T-shaped parts, wherein, as shown in FIG. 2, the flange 22 carries the respective sections 29 or 30 or 31 of the plate 16 and is attached to the web 33 steered foot 24 each represents the connection with the door body 1.
  • the spacers 18, 19 can, in addition to the T-shaped embodiment, also be designed as round or other webs, as are shown, for example, in FIGS. 3, 4, 5, 6.
  • the individual spacers are spaced from each other, which leads to a further weight reduction for the entire coke oven door construction. This is associated with less material expenditure, but also less installation effort.
  • the vapor and gaseous coking products can be sucked unhindered past the heat-resistant plate 16 into the vertical gas collecting space 7 and via the riser pipe from the coke oven.
  • various embodiments for the spacers 18, 19 are possible, and in particular the embodiments shown in FIGS. 5 and 6 also offer a possibility of influencing the volume of the gas collecting space 7.
  • connection 37 is provided for gas bubbles 36, which close the area between the heating wall and the webs 23 of the spacers 18, 19 in such a way that no gases or free-flowing coal can penetrate into this area.
  • the gas bubbles 36 can be filled, for example, with nitrogen and inflated via the connection 37.
  • 5 and 6 show embodiments in which the insertion of the coke oven door is facilitated by tilting the plate 16.
  • the plate 16 made of highly heat-resistant metal as the outer boundary of the gas collecting space 7 is heated, among other things, by the gas flowing past, which leads to better cooking of the end face regions of the furnace filling. Due to the better cooking of these areas, lower emissions occur when coke is pressed. As a result, the dedusting units used in coke pressing can be substantially relieved and have a lower output.
