Definitions

  • the present invention relates to a novel device for burning dust-like materials, in particular activated coke dust contaminated with pollutants from filter systems, sewage sludge dust and the like.
  • the present invention is therefore based on the object of providing a device for the combustion of such contaminated materials, with which the special combustion conditions required for the safe destruction of harmful substances are achieved with a structurally simple and compact structure are easy to control.
  • the combustion device should preferably be suitable for a continuous material throughput, so that economical operation is also possible, in particular in a direct combination with devices in which the contaminated materials are produced.
  • the combustion device is characterized by a combustion chamber with an inlet opening on one side for the material to be burned and an outlet opening opposite the inlet opening for flue gases resulting from the combustion, in the region of the inlet opening a device for introducing the material to be burned, Dusty material mixing primary air and in the area of the outlet opening a device for introducing secondary air are provided such that the secondary air flows on the one hand towards the primary air in the direction of the inlet opening and on the other hand is set into a swirl flow around a combustion chamber axis running through the inlet and outlet opening .
  • the arrangement of the inlet opening and the - opposite in the flow direction or in the flow direction - the outlet opening enables a continuous, continuous combustion process, but due to the inventive division of the combustion air into primary and secondary air and thereby the counter-swirl flow of the secondary air, the dwell time of the Material or the dust-air mixture is sufficiently long, especially as a result of very intensive swirling and mixing, ie by forming a mixture that is practically homogeneous over the entire firing path, an extraordinarily high firing temperature of 1200 ° to 2000 ° C. or even higher can be.
  • the increase in the residence time achieved according to the invention leads to the advantage that the combustion chamber can be made relatively short and the device according to the invention as a whole can be made very compact.
  • the combustion can be controlled by metered supply of the primary and secondary air in such a way that stoichiometric combustion is advantageously achieved at least approximately.
  • the so-called excess air factor ⁇ is at least approximately equal to 1.
  • ⁇ is in the order of magnitude of approximately 1.02. This extremely small excess of air is of decisive advantage insofar as a reduction in the fire temperature is avoided by excessive excess of air, ie the firing temperature can be kept very high and also permanently. Complete combustion with thermal destruction of all pollutants occurring in practice, in particular also of dioxins, is guaranteed.
  • the term "complete combustion" means that the invention contains only an extremely small proportion of unburned substances, namely ⁇ 0.1%, in the flue gas.
  • the limit value of a maximum of 5% unburned that is usually required here is thus advantageously far below.
  • the preferably close stoichiometric combustion also advantageously results in the formation of new dioxins and the like avoided because there is not enough oxygen available for such reactions because of the small excess of air, in particular about 2%.
  • a very stable flame is also achieved (flame stabilization), i.e. a "tearing off” of the flame is advantageously avoided. Therefore, it is advantageously sufficient to arrange a so-called pilot and auxiliary burner in the area of the inlet opening, which is generally only “switched on” for the first ignition of the combustion, but can then be switched off during further operation because the combustion stabilizes itself.
  • a so-called pilot and auxiliary burner in the area of the inlet opening, which is generally only “switched on” for the first ignition of the combustion, but can then be switched off during further operation because the combustion stabilizes itself.
  • the outlet opening is followed by a post-combustion zone, into which - in addition to the primary and secondary air - tertiary air is then introduced.
  • combustion can be carried out substoichiometrically within the combustion chamber, with total, ie primary, secondary and tertiary air, then preferably again achieving approximately stoichiometric combustion with ⁇ ⁇ 1.02.
  • the substoichiometric combustion in the combustion chamber leads to a higher combustion temperature and thus to an even safer removal of the pollutants, in particular dioxins.
  • the afterburning caused by supplying tertiary air practically leads to completing the combustion in such a way that overall the intended complete combustion is achieved.
  • the primary air is also set into a swirl flow, the swirl directions of primary air and secondary air being directed in opposite directions.
  • the tertiary air is preferably also set in a swirl flow; the swirl directions of secondary air and tertiary air are then directed in opposite directions.
  • the device according to the invention is thus a “multi-stage counter-swirl burner”.
  • the residence time spectrum of the material to be burned is increased considerably.
  • a device 1 for burning dusty materials mainly consists of a combustion chamber 2 with a one-sided inlet opening 4 for the material to be burned and also for supplied combustion air, and with an outlet opening 6 opposite the inlet opening 4 in the throughput direction for flue gases generated by combustion.
  • the inlet and outlet openings 4, 6 are preferably arranged coaxially to one another, i.e. a combustion chamber axis 8 runs in particular centrally through the inlet and outlet openings 4, 6.
  • the material to be burned is in dust form, i.e. in the ground state, fed via a pipeline 10, this pipeline 10 opening into the area of the inlet opening 4.
  • a certain percentage of carrier air is added to it, so that a dust-air mixture already emerges from the pipeline 10.
  • additional combustion air is supplied to this mixture.
  • the combustion air is now at least in Primary air P and secondary air S are divided, in the area of the inlet opening 4 a device 12 for introducing the primary air P to be mixed with the material to be burned and in the area of the outlet opening 6 a device 14 for introducing the secondary air S are provided such that the secondary air S on the one hand the primary air P or the resulting dust-air mixture flows in the direction of the inlet opening 4 and on the other hand is set into a swirl flow about the combustion chamber axis 8.
  • This swirl flow of the secondary air S illustrated in FIG. 1 and also in FIG. 4 with the aid of flow lines, an increase in the residence time of the combustible mixture within the combustion chamber 2 is achieved as well as such an intensive swirling and mixing that an almost homogeneous combustion mixture is produced. This results in optimal combustion conditions.
  • the device 12 for introducing the primary air P is designed only in the form of a short, preferably cylindrical, piece of pipe 16 which simultaneously forms the inlet opening 4 in such a way that the primary air P is initially essentially straight, taking the material to be burned with it, ie as an approximately homogeneous flow, is blown through the inlet opening 4 in the direction of the outlet opening 6.
  • the combustion mixture is then swirled intensively by the opposite swirl flow of the secondary air S.
  • the device 12 for introducing the primary air P is designed such that the primary air P, on the one hand, taking the material to be burned with it the secondary air S flows in the direction of the outlet opening 6 and, on the other hand, is likewise set into a swirl flow about the combustion chamber axis 8.
  • the swirl direction of the primary air P or the dust-air mixture is opposite to the swirl direction of the secondary air S.
  • a swirl flap device 18 with swirl flaps 20 that are inclinable in particular to change the swirl is arranged within the inlet opening 4 to generate the swirl flow of the primary air P, ie as a device 12 for introducing the primary air P.
  • This swirl flap device 18 is designed in the manner of a turbine wheel or an axial fan, the swirl flaps being arranged evenly distributed over the circumference of the inlet opening 4 and being able to be pivoted, in particular, steplessly about radial axes, namely between an axially aligned arrangement and an arrangement approximately perpendicular thereto, then opening 4 is almost closed. As a result, a certain regulation of the air volume can also be achieved.
  • the swirl flap device 18 serves to vary the swirl effect or swirl intensity of the primary air-dust mixture.
  • the device 14 for introducing the secondary air S consists essentially of a blow-in ring 22 which surrounds the outlet opening 6 or is concentric with the outlet opening 6 and which has an inner surface 24 which widens conically in the direction of the combustion chamber 2 and several has air slots 26 distributed around the circumference.
  • These louvers 26 extend from the outer circumference 28 of the blowing ring 22 to the inner surface 24 and are aligned such that the secondary air S supplied from the outside flows through the louvers 26 and is thereby displaced into the swirl flow directed into the combustion chamber 2.
  • the blowing ring 22 is expediently formed by a plurality of individual ring elements 30, which each form or limit the air slots 26 between them.
  • the blowing ring 22 preferably consists of approximately twenty-four individual elements, so that a total of twenty-four air slots are provided in a distribution that is uniform over the circumference.
  • the number of ring elements 30 or air slots 26 can vary greatly, depending on the design of the burner output and the amount of air required in each case.
  • the air slots 26 of the blow-in ring 22 are designed in a nozzle-like manner with respect to their effective flow cross-section such that the secondary air S supplied from the outside with a specific, ie, determined by the air volume required for complete combustion at ⁇ ⁇ 1, through the narrowed louvers 26 one such receives high flow velocity that it prevents the penetration of fuels into the air slots 26.
  • the air slots 26 are advantageously practically self-cleaning or self-cleaning by the injected secondary air S.
  • the entire combustion air is supplied as primary and secondary air P, S.
  • the total volume of primary and secondary air P, S to be supplied per unit of time can preferably be regulated such that the combustion within the combustion chamber 2 is always approximately stoichiometric with an excess air number ⁇ of approximately 1 to 1. 05, in particular about 1.02.
  • Complete combustion is achieved on the one hand, and on the other hand the combustion temperature is also extremely high because the combustion is not cooled by the air supplied.
  • a higher air excess of e.g. ⁇ ⁇ 1.9 can be driven, but the advantage of good and stable combustion remains.
  • a "division into three" of the total combustion air required is now provided, in addition to the primary and secondary air P, S, tertiary air T is also supplied.
  • a post-combustion zone 32 with a device 34 for supplying the tertiary air T expediently adjoins the outlet opening 6 in the direction remote from the combustion chamber 2.
  • the combustion within the combustion chamber 2 can take place sub-stoichiometrically with an excess air number or "lack of air" ⁇ ⁇ 1. This can result in an even higher temperature absolutely safe destruction of pollutants, especially dioxins, can be achieved.
  • the combustion is then completed in the afterburning zone 32 by supplying the tertiary air T, the tertiary air T being supplied at a volume per unit time that the overall combustion preferably takes place approximately stoichiometrically ( ⁇ approximately 1.02).
  • the device 34 for supplying the tertiary air T is designed such that the tertiary air T flows on the one hand in the direction of the post-combustion zone 32 facing away from the combustion chamber 2, but on the other hand also in a swirl flow is offset, thereby increasing the residence time within the afterburning zone 32.
  • the swirl directions of tertiary air and secondary air are opposite to each other. As a result, the fuel mixture is mixed again and swirled.
  • the device 34 for supplying the tertiary air T consists of a concentric with the outlet opening 6 blowing ring 36, which basically corresponds in its design to the blowing ring 22 provided for the secondary air S, so that for the sake of simplicity reference is made to the above statements .
  • the same or functionally corresponding parts are provided with the same reference numerals.
  • the conical inner surface 24 of the blowing ring 36 widens in the direction facing away from the combustion chamber 2.
  • the air slots 26 are also formed in the blowing ring 36 so that the tertiary air T receives such a high flow rate that it effectively prevents the penetration of substances from the flue gases.
  • cold fresh air is expediently used (with outside or ambient temperature).
  • the primary air P and preferably also the secondary air S are expediently heated before being introduced into the combustion chamber 2.
  • the combustion chamber 2 is delimited by a chamber wall 38, which in turn is surrounded by an outer jacket 40 such that a cavity 42 enclosing the chamber wall 38 is formed between the chamber wall 38 and the jacket 40.
  • An air inlet 44 opens into this cavity 42 in a region close to the outlet opening 6, and the cavity 42 merges into the inlet opening 4 on the side facing away from the outlet opening 6.
  • a helical partition 46 is preferably arranged within the cavity 42 between the chamber wall 38 and the outer jacket 40 such that the air supplied via the air inlet 44 flows helically around the chamber wall 38 in the direction of the inlet opening 4.
  • the chamber wall 38 is advantageously cooled.
  • the combustion chamber 2 is also lined with an inner jacket 48 made of a refractory material in the device 1 according to the invention.
  • the refractory materials commonly used for this are however only stable up to an average temperature of around 1600 ° C. Therefore, due to the very high combustion chamber temperatures of up to 2000 ° C., it is particularly advantageous if a cavity 50 enclosing the latter is formed between the chamber wall 38 and the refractory inner jacket 48 for a cooling medium that cools the inner jacket 48.
  • the secondary air S is used as the cooling medium, for which purpose preferably the air supplied via the air inlet 44 and the cavity 42 formed between the chamber wall 38 and the outer jacket 40 in the area lying in front of the inlet opening 4 into the primary air P and the secondary air S is divided.
  • the secondary air S then flows through the coolant cavity 50 in the direction of the supply device 14 arranged at the outlet opening 6.
  • the coolant cavity 50 expediently merges directly into an annular chamber 52 surrounding the blowing ring 22, from which the secondary air S passes through the air slots 26 flows. This particularly advantageous measure thus on the one hand achieves effective cooling of the inner jacket 48, and on the other hand the secondary air S is simultaneously heated.
  • a pilot and auxiliary burner 54 which can be operated in particular with light oil, is arranged in the region of the inlet opening 4.
  • This burner 54 is used, on the one hand, for the first ignition in the start-up mode of the combustion device 1 according to the invention regular combustion within the combustion chamber 2 is reached, this burner 54 can be switched off.
  • the pilot and auxiliary burner 54 is preferably automatically controlled by a control so that in the event of an irregularity in the combustion occurring within the combustion chamber 2, the pilot and auxiliary burner 54 is switched on automatically for a certain time.
  • the control unit which switches the burner 54 has on the one hand the monitoring of the combustion taking place in the combustion chamber 2 and on the other hand the flame of the burner 54, in particular photocells or similar sensors.
  • the combustion chamber 2 is arranged directly on a combustion boiler 56, in particular a waste incineration plant, in such a way that the smoke gases escaping through the outlet opening 6 are introduced directly into the combustion chamber 58 of the combustion boiler 56.
  • the arrangement of the device 1 according to the invention on the combustion boiler 56 is selected such that the flue gases enter the combustion chamber 58 in an area where the operating temperature is strig 1200 ° C. This advantageously prevents hypothermia in the combustion chamber flame due to edge influences and also streak formation in the combustion chamber.
  • the device 1 according to the invention is particularly suitable for burning the activated coke occurring in the waste incineration plant, with a continuous throughput, i.e. constant disposal is possible.
  • thermal support for the combustion occurring within the combustion boiler 56 is achieved.
