Definitions
- the invention relates to an apparatus and method for supplying combustion air for the combustion of coking gas in coking chambers constructed of flat construction and arranged as a battery coke ovens, for the so-called non-recovery or heat recovery process.
- the device comprises at least one ventilation opening per coking chamber, which runs through the respective coke oven door or its framing wall and ventilation openings for the supply of secondary air in the heating cables.
- Each ventilation opening is associated with a movably mounted closure element.
- All closure elements are mechanically connected to at least one actuating element which is controlled and driven from a central location.
- the actuator continuously actuates the closure elements depending on the need for combustion air in the coking chamber.
- the mechanical connection of each individual closure element with the central control element can be made separately, wherein in particular the starting position of a single closure element at the beginning of the coking process of the associated coking chamber can be made independently of the other closure elements of the adjacent coking.
- the heating of heat recovery furnaces is usually carried out by combustion of the gas formed during the coking.
- the combustion is controlled so that a portion of the gas burns above the coal charge with primary air in the furnace chamber.
- This partially combusted gas is supplied via channels, which are also referred to as "downcomers", the heating cables in the bottom of the furnace chamber and completely burned here by adding further combustion air, the secondary air.
- the secondary air is sucked in through openings near the floor and passed through channels in the heating cables, which run essentially horizontally under the coke oven chamber.
- the openings for primary and secondary air are either permanently open or provided with flaps for adjusting the amount of air to be sucked.
- the object of the invention is therefore to remedy the described deficiencies in an economical manner and to ensure an optimized supply of primary and / or secondary air.
- the reliability must be ensured even at the usually given high temperatures and heavy contamination.
- the invention solves the problem by a device for supplying combustion air for the combustion of coking gas in coking chambers constructed of flat construction and arranged as a battery coke ovens is provided, wherein the ventilation device consists of at least one ventilation opening per coking chamber, through the respective coke oven door or its framing wall runs and for each ventilation opening a movably mounted locking element is provided, wherein
- all the closing elements of the ventilation openings are mechanically connected to at least one adjusting element which is controlled and driven from a central location, the closure elements are to be actuated by means of the actuating element, depending on the need for combustion air in the coking chamber,
- each closure element with the central actuator can be made separately, in particular the starting position of a single closure element at the beginning of the coking process of the associated coking chamber can be adjusted separately and independently of the other closure elements of the adjacent coking.
- connection between the closure element and the adjusting element the following is to be understood as meaning that the two elements can be detached from one another directly or via a coupling element such as a lever, a cable, a chain, a lever arm, etc., as well as combinations of these elements can be connected.
- a coupling element such as a lever, a cable, a chain, a lever arm, etc.
- actuating element to be designed as a circulating chain or a steel cable.
- a screw as an actuator. All of these control elements allow a permanent operation in one direction, which is very advantageous for the continuous overall process.
- the device according to the invention can be designed to the effect that closure plates are used as closure elements, which are mounted such that they are moved during operation by the connecting element substantially parallel to the oven door.
- closure elements are formed as vertical closure plates and are mounted vertically or horizontally rotatable about a central axis.
- the closure elements are formed from at least two overlapping and mutually displaceable facets, with facets ideally releasing a polygonal and point-symmetrical or approximately circular cross-section at a partial opening.
- An even further improvement is to make the closure elements cone-shaped, wherein the tip is directed to the furnace interior in the installed state.
- This embodiment can be further optimized in that the ventilation opening have the same or a larger opening angle than the associated conical closure elements.
- the intake air is minimally swirled in the region of the closure element and the ventilation opening and formed into a gas jet, regardless of the size of the released cross-section.
- the conical closure element is moved via a lever construction and / or a spindle in the longitudinal axis direction of the opening, so that in a partial opening a circular annular gap is released.
- the ventilation device can be improved in that the closure element is connected to the actuating element such that it is automatically released in the end position, with complete closure of the ventilation opening, from the control element.
- the invention further comprises a method for supplying combustion air in coke ovens, in which the aeration device according to the invention described above is used in one of its variants, wherein the sequence of the method is as follows: a) After emptying and refilling a Coking chamber, the closure elements are connected in their initial position, which is the complete or almost complete release of the vent, with a central actuator. b) During the cooking time, the closure elements are actuated by the central control element continuously and substantially at a constant average speed or setting frequency, so that the ventilation openings are closed continuously. c) At the latest at the end of the cooking time of a coking chamber, the closure elements have the ventilation openings of the coking chamber completely closed and can be released from the actuator. d) After emptying and refilling, the process is restarted with step a).
- An improved variant of the method is that the closure element is automatically released in the end position of the actuator.
- At least two central adjusting elements are provided, wherein the one adjusting element, the closure elements for the primary air and the other central actuating element moves the closure elements for the secondary air.
- the two control elements are completely independently controllable during the entire cooking time.
- a central actuator is operated continuously and substantially at the same speed or setting frequency.
- FIG. 1 shows a coke oven 1 in the front view.
- the coke oven 1 has in the front surface on a coke oven door 2, in which two ventilation openings 3 are arranged for the primary air.
- Below the coke oven door 2 dashed lines 4 are shown, which extend under the oven room.
- the ventilation openings 5 for the supply of secondary air in these heating cables 4 are located near the bottom below these heating 4.
- each closure element consists essentially of a closure plate 9 and a lever arm 10 and is mounted on an axis 8, about which the respective closure element can be rotatably moved.
- the lever arms 10 of the closure elements 6 are detachably connected to a peripheral chain 11 and the closure elements 7 are detachably connected to a revolving chain 12.
- the closure elements 6 are moved counterclockwise by the angle ⁇ and the closure elements 7 in the clockwise direction by the angle ß.
- the chains themselves are driven via the central control elements 13 and 14, respectively.
- Fig. 2 shows the front view of two coke ovens 1, which stand for a larger coke oven battery, as indicated by the two arrows I and Il.
- the two coke ovens 1 shown are in different cooking states.
- the coke oven 1 shown on the right is located at the beginning of the coking process, therefore cover the closure elements 6, the ventilation openings 3 barely.
- the lifting arm 10 is connected in this embodiment via a smaller chain 15 with the revolving chain 11.
- the structure in the area of the ventilation openings 5 for the secondary air is analog.
- the closure elements 7, or their lever arms 10 are connected via smaller chains 16 with the revolving chain 12.
- the air supply in the left coke oven 1 is already completely closed and the lever arm 10 and the chain 15 is released from the circulating chain 11.
- the closure elements 7 for the control of the secondary air of the coke oven 1 shown on the left are just before the closure, but not yet completely closed. Thus, it is very easy to understand that each coke oven 1 can be controlled individually despite a common central control.
- FIG. 3 A particular embodiment of the closure element 6 and 7 is shown in FIG. 3.
- a rotationally symmetrical closure element 6 is shown, which has a closure head 17 in the form of a conical stub which is fastened to a cylindrical guide rod 18.
- the guide rod is fixedly connected to a spring bridge 19, which is fastened to the coke oven door 2.
- the guide rod 18 is guided in a guide tube 20 and connected to the rear end via a small chain 15 with the circulating chain 11.
- the springs of the spring bridge 19 are biased by expansion, so that the ventilation opening 3 is largely open.
- the bias is to be selected such that after the relaxation of the chain 15 and the spring bridge 19, a complete closure of the ventilation opening 3 takes place.
