Definitions

  • This invention relates to a device and a method for supplying combustion air for the combustion of coking gas in cokemaking chambers of coke ovens built in flat-type construction and arranged as a battery of coke ovens for the so-called non-recovery or heat-recovery process.
  • This device at least comprises a vent port for each cokemaking chamber, said vent port extending through the relevant coke oven door or its wall surrounding it, as well as vent ports for supplying secondary air into the heating flues.
  • a freely-supported locking element is provided for each vent port.
  • All locking elements are mechanically connected to at least one adjusting element controlled and driven from a central point.
  • the adjusting element continuously actuates the locking elements depending on the demand for combustion air in the cokemaking chamber.
  • the mechanical connection of each individual locking element with the central adjusting element can be effected separately, wherein especially the starting position of each individual locking element at the beginning of the cokemaking process of the pertaining cokemaking chamber can be adjusted independently of the other locking elements of the adjacent cokemaking chambers.
  • Heating of heat-recovery ovens is usually performed by combustion of gas evolving on cokemaking. Combustion is controlled in such a manner that part of the gas above the coal charge burns off with primary air in the oven chamber. This partly burnt gas is fed through channels that are also designated as “downcomers” to the heating flues in the oven chamber sole and completely burnt there by the addition of further combustion air, which is called secondary air.
  • This invention solves this task by providing a device for supplying combustion air for the combustion of coking gas in cokemaking chambers of coke ovens built in flat-type construction and arranged as a battery of coke ovens, wherein the venting device consists of at least one vent port for each cokemaking chamber, said vent port extending through the relevant coke oven door or through its wall surrounding it, and wherein a freely-supported locking element is provided for each vent port, wherein
  • connection between the locking element and the adjusting element as used hereunder shall be understood to mean that both elements may be connected to each other in a detachable way through a coupling element, for example a lever, rope tackle, chain, lever arm, etc. as well as combinations of these elements.
  • a coupling element for example a lever, rope tackle, chain, lever arm, etc. as well as combinations of these elements.
  • Advantageous embodiments provide for configuring the adjusting element as a rotating chain or as a steel cable.
  • Using a screw spindle as adjusting element is another suitable embodiment. All these adjusting elements permit a permanent actuation into one moving direction which is very advantageous for the continuous overall process.
  • the device embodying this invention can be configured in such a manner that locking plates are installed as locking elements, said locking plates being supported in such a way that when actuated by the coupling element they are moved mainly in parallel to the oven door.
  • vent port For a directed flow of primary gas it is of advantage for the vent port to be of a rotary-symmetrical shape. Therefore, the use of locking elements configured as upright standing locking plates and supported in vertically or horizontally rotatable arrangement around a central axle is advantageous.
  • the locking elements are formed by at least two overlapping and reciprocally slideable facettes, with both facettes ideally exposing a polygonal and point-symmetrical or nearly circular cross-section when partly opened.
  • a still advanced improvement resides in configuring the locking elements in conical shape, with the tip pointing towards the oven interior when built-in.
  • This embodiment can still be further optimised in such a way that the vent port has the same or a wider angle of aperture than the pertaining conical locking elements.
  • the aspirated air is whirled-up minimally in the area of the locking element as well as in the area of the vent port and shaped to a gas jet independently of the size of the exposed cross-section.
  • the conical locking element is moved via a lever structure and/or a spindle in the longitudinal direction of the vent port so that a circular ring gap is exposed when partly opened.
  • the ventilation device can be further improved by connecting the locking element with the adjusting element in such a way that it is automatically released from the adjusting element when being in the end position and when the vent port has been completely closed.
  • This invention furthermore comprises a device for supplying combustion air in coke ovens, in which the ventilation device embodying this invention as described before is implemented by one of its embodiment variants, with the sequence of the method being as set forth below:
  • An improved variant of this method is that the locking element being in the end position is automatically released from the adjusting element.
  • At least two central adjusting elements are provided for, wherein one adjusting element thereof actuates the locking elements for primary air and wherein the other central adjusting element actuates the locking elements for secondary air. Throughout the entire carbonisation time, the two adjusting elements are controllable completely independently of each other.
  • This invention also encompasses the use of the ventilation device embodying this invention in one of the embodiment variants outlined hereinabove with a method for supplying combustion air in cokemaking chambers of coke ovens built in flat-type construction and arranged as a battery of coke ovens.
  • FIG. 1 shows a coke oven 1 in a front view.
  • coke oven 1 has a coke oven door 2 in which two vent ports 3 for primary air are arranged.
  • heating flues 4 Located beneath said coke oven door 2 and illustrated by dotted lines are heating flues 4 extending under the oven space.
  • the vent ports 5 for supplying secondary air into these heating flues 4 are arranged near the bottom beneath said heating flues 4 .
  • FIG. 1 shows the locking elements 6 for said vent ports 3 of the primary air supply and the locking elements 7 for the vent ports 5 of the secondary air supply.
  • Each locking element mainly consists of a locking plate 9 and a lever arm 10 and it is supported at an axle 8 around which said locking element can be moved in rotating motion.
  • the lever arms 10 of said locking elements 6 are connected in a detachable way with a rotating chain 11 and the locking elements 7 are connected in a detachable way with a rotating chain 12 .
  • FIG. 2 shows the front view of two coke ovens 1 representing a major coke oven battery as indicated by the two arrows I and II. These two coke ovens 1 are at different stages of coal carbonisation.
  • the coke oven 1 shown on the right side is in the initial stage of coal carbonisation, and therefore the locking elements 6 hardly overlap the vent ports 3 .
  • the lever arm 10 is connected via a minor chain 15 to the rotating chain 11 .
  • the arrangement in the area of the vent ports 5 for secondary air is analogous.
  • the locking elements 7 and, respectively, their lever arms 10 are connected via minor chains 16 to the rotating chain 12 .
  • FIG. 3 A special embodiment variant of the locking elements 6 and 7 is illustrated in FIG. 3 .
  • a rotary-symmetrical locking element 6 having a locking head 17 in form of a truncated cone to which a cylindrical guiding rod 18 is fastened.
  • the guiding rod is firmly connected to a spring bridge 19 fastened to said coke oven door 2 .
  • the guiding rod 18 is guided in a guiding tube 20 and connected with its rear end via a small chain 15 to the rotating chain 11 .
  • the springs of the spring bridge 19 are pre-stressed by expansion so that the vent port 3 is largely open.
  • the spring bridge 19 is relieved, the locking element 6 is moved in the direction of the coke oven door 2 , and the locking head 17 is introduced into the conical vent port 3 .
  • the pre-stressing shall be chosen such that after relief of the chain 15 and spring bridge 19 a complete closure of vent port 3 is achieved.
