Definitions

  • the invention relates to a pre-furnace combustion system for the combustion of solid combustible material with a high ash content, in particular of bark and chips, with a combustion chamber closed at the bottom by a grate, to which the combustible material is fed from above through a supply shaft, the combustion chamber being made of a jacket made of refractory material is surrounded, which is penetrated by a combustion channel connecting the combustion chamber with the downstream boiler, which has an opening for the supply of secondary air, and wherein in the jacket another opening, preferably closable by a control flap adjusted by the boiler, for the supply of primary air is provided under the grate.
  • a pre-furnace combustion system for the combustion of solid combustible material with a high ash content, in particular of bark and chips, with a combustion chamber closed at the bottom by a grate, to which the combustible material is fed from above through a supply shaft, the combustion chamber being made of a jacket made of refractory material is surrounded
  • a disadvantage of the known system is the fact that there is often bridging of the combustible material in the supply shaft and that the system can only be operated for a short time, approximately one hour, after which, owing to the large ash content and pollutant content of the combustible material, in particular Wood bark, the entire system needs to be cleaned. This work is tedious and uncomfortable to perform, apart from the fact that no heat is supplied to the central heating boiler during the cleaning period.
  • the invention has for its object to avoid the disadvantages described and to improve a pre-furnace combustion system of the type described in such a way that there are no bridges in the supply shaft and thus malfunctions of the combustion process, the efficiency or the utilization of the combustible components of the Firing good should be significantly improved.
  • the invention solves this problem in that a carburetor ring with a standing axis is arranged at a distance above the grate within the jacket and above the combustion channel, which carburetor ring has a cover surface inclined towards its central opening, a screw leading to this opening and this carburetor ring is rotatable about its axis by a drive, so that the screw conveys the material to be burned through the opening of the carburetor ring.
  • the worm preferably leads through the opening of the carburetor ring, as a result of which bridging in the carburetor ring is also avoided with certainty.
  • the worm itself can also be driven to rotate, however, for the sake of less effort, it is within the scope of the invention more favorable if the worm is fixed and is held at its upper end by a rod which lies within a hollow shaft connected to the carburetor ring is connected to the drive of the carburetor ring.
  • This arrangement is structurally particularly simple and effective.
  • the rod holding the worm and the hollow shaft support each other.
  • a periodic rotation of the carburetor ring is generally sufficient to reliably supply the firebox with fuel and to avoid bridging and to save energy.
  • the most favorable speed for rotating the carburetor ring can easily be achieved by means of a geared motor.
  • a preferred embodiment of the invention is that the carburetor ring can be raised and lowered to change its distance from the grate. In this way, the size of the combustion chamber can be adjusted, which brings another control option for the system, in addition to controlling the primary and secondary air supply, in particular from the draft regulator of the boiler.
  • the above-mentioned height adjustment of the carburetor ring can be carried out by raising or lowering the hollow shaft without any problems and with little energy expenditure.
  • the rotation of the carburetor ring can also be used for a further purpose: If, according to the invention, a grate cleaner is provided between the grate and the carburetor ring, which rotates relative to the grate, residues can be stripped from the grate by this rotation, so that the grate is less frequent needs to be cleaned.
  • the grate cleaner In front preferably the grate cleaner has at least one rod sliding over the grate.
  • the arrangement can be made in such a way that the grate cleaner has vertical drive rods which are guided so as to be longitudinally displaceable in openings in the carburetor ring.
  • the rust cleaner is always reliably taken along when the carburetor ring is rotated and the height adjustment of the carburetor ring is still permitted at all times.
  • the grate can also be rotationally coupled to the carburetor ring, so that in normal operation the carburetor ring and grate rotate while the grate cleaner stops. According to a simple embodiment, this can be achieved in that the grate carries vertical drive rods which are guided so as to be longitudinally displaceable in openings or circumferential grooves of the carburetor ring in order to enable the aforementioned height adjustment of the carburetor ring.
  • the worm extends in the lowest position of the carburetor ring by the stroke length of the carburetor ring into the hollow shaft.
  • effective worm threads are also available when the hollow shaft and thus the carburetor ring are raised.
  • the screw can easily consist of a metal band twisted about its longitudinal axis, which only has to consist of a correspondingly fire-resistant material.
  • FIG. 1 shows a vertical section through a first embodiment of the invention.
  • FIG. 2 is a section along the line 11-11 of FIG. 1.
  • FIGS. 3 and 4 each show an embodiment variant in section similar to FIG. 1.
  • the system 1 has a storage shaft 4 for receiving the combustible material to be burned, which can be formed in particular from wood bark, sawdust, wood chips, but also from household waste (also moist, but without ceramic or metallic components).
  • the combustible material can optionally also be mixed with coal dust.
  • the supply shaft 4 is delimited by a housing 5 which widens upwards like a funnel and is closed at the top by a cover wall 6. At the front there is an opening 8, which can be closed by a filling door 7, for loading the supply shaft 4.
  • the housing 5 sits down in an annular jacket 9 made of refractory material, eg.
  • B. refractory concrete continues, which encloses a combustion chamber 10, in which the fired material is burned.
  • a combustion duct 11 passing through the casing 9 leads to the boiler 2, which combustion duct is also surrounded by a refractory casing 12 which is penetrated by an opening 13 for the supply of secondary air.
  • the opening 13 can be closed by a flap 14.
  • the combustion chamber 10 is closed off by a grate 15 which has circular openings for the ashes arranged around the axis of the combustion chamber 10 and which falls into an ash chamber 16 which is accessible through an opening 18 in the jacket 9 which can be closed by a cleaning door 17 .
  • a gasifier ring 19 is arranged within the circular shell 9 above the grate 15 at a distance therefrom, said carburetor ring 19 being concentric to the axis of the combustion chamber 10 and being rotatable about this axis.
  • the carburetor ring 19 is fastened by means of struts 20 to a hollow shaft 21 which extends upwards in the storage shaft 4 and is mounted in the top wall 6 so as to be longitudinally displaceable and rotatable.
  • This hollow shaft 21 is driven by a geared motor 22 for rotation, which is periodically switched on and off by a timer 23, so that the hollow shaft 21 and with it the carburetor ring 19 rotate intermittently.
  • the hollow shaft 21 there is a rod 24 which is suspended with its upper end on an attachment 25 of the geared motor 22. This suspension will be described later in connection with FIG. 4.
  • the rod 24 carries a screw 26, the lower end of which can be fastened to the grate 15, in particular when the screw 26 is stationary.
  • the hollow shaft 21 can be adjusted in height and adjusted in the set position by means of an adjusting mechanism (not shown), so that the height of the carburetor ring 19 in the jacket 9 and thus the height of the combustion chamber 10 below the carburetor ring 19 can be adjusted.
  • a grate cleaner 27 which has three rods 28 which slide over the grate 15 and which project outward in a star shape from a ring 29 surrounding the lower end of the screw 26.
  • the outer ends of these rods 28 carry upwardly projecting driver rods 30 which pass through openings 31 of the carburetor ring 19 and are guided in a longitudinally displaceable manner in these openings. In this way, when the carburetor ring 19 is rotated, the grate cleaner 27 is carried along for the rotary movement and scrubs the grate 15 free of impurities by means of the rods 28.
  • the primary air supply to the combustion chamber 10 takes place through the grate 15 from below, the air flowing through a channel 32 in the casing 9 and through the opening 18 to the ash chamber 16 or to the grate 15.
  • the upper end of the channel 32 can be closed by a flap 33.
  • the two flaps 14, 33 are controlled by the draft regulator 3 of the boiler 2 such that, depending on the boiler temperature, the flap 14 controlling the secondary air supply is closed and the flap 33 controlling the primary air supply is opened or vice versa.
  • the corresponding control lines 34 for this are indicated schematically by dashed lines.
  • the firing material introduced into the chute 4 through the filling opening 8 collects in the chute 4 above the carburetor ring 19.
  • the heat developed in the combustion chamber 10 and in the combustion channel 11 causes the jacket 9 and the carburetor ring 19, which is likewise made of refractory material, to reach a relatively high temperature brought, which causes not only a pre-drying of the firing material located in the storage shaft 4, but also a degassing of at least the parts of the firing material resting on the gasifier ring 19.
  • An additional preheating of the fired material takes place through the metallic screw 26, which conducts the heat from the combustion chamber 10 into the storage shaft 4.
  • the gases developed here are torn into the combustion channel 11 by the train exerted by the chimney via the central heating boiler 2 through the combustion channel 11 and burn there.
  • the air required for combustion is supplied through the primary air duct 32 and / or through the secondary air duct formed by the opening 13.
  • the strength of the combustion in the combustion chamber 10 can be regulated on the one hand by the aforementioned air supply from the draft regulator 3 of the boiler 2, and on the other hand by adjusting the height of the carburetor ring 19 in the form of spring tines 35 is moved at least intermittently, on the other hand the carburetor ring 19 forming a bearing surface for the combustible material rotates intermittently about its vertical axis, so that the combustible material passes into the combustion chamber 10 via the top surface 37 of the carburetor ring 19 inclined towards the central opening 36 thereof slips.
  • the carburetor ring 19 is provided with a collar 38 which extends downward from its opening 36 and which holds the combustible material sliding into the combustion chamber 10 together.
  • This collar 38 can be formed by a piece of pipe.
  • the screw 26 can be formed in a simple manner by means of a twisted metal band which pulls the fuel to be rotated into the opening 36 of the carburetor ring 19 when the carburetor ring 19 rotates.
  • the hollow shaft 21 can be designed with an enlarged diameter in its lowermost region, which receives this screw end.
  • the embodiment according to FIG. 3 differs from that according to FIGS. 1 and 2 essentially only in the design of the carburetor ring 19, the grate 15 and the grate cleaner 27.
  • the carburetor ring 19 consists of a hollow truncated cone, in particular of temperature-resistant metallic or ceramic material. This enlarges the combustion chamber 10 located under the carburetor ring 19 in the edge zones of the carburetor ring 19.
  • the grate 15 is pulled upwards in its edge areas, so that a trough-shaped depression for the burning material results in the middle.
  • the radial rods of the grate cleaner 27 are also raised in the edge area, so that the grate 15 is cleaned over its entire top surface.
  • the system can be provided with an additional screw which conveys the firing material from a large storage container outside the housing 5 into the latter. Protection against burn-back can be provided by a sprinkler system known per se.
  • Another advantageous design variant consists of hanging the grate 15 on the screw 26, but otherwise arranging it vertically in the jacket 9. This results in the possibility of lowering the grate 15 by means of the screw 26, for. B. if there is a larger residue mass on the grate that cannot be brought through the grate openings. When the grate is lowered, this residue can be removed through the cleaning door 17. The lowering of the grate also offers the possibility of causing an additional primary air supply above the grate 15.
  • the efficiency of the system according to the invention is considerably higher than that of the systems known to date. Except for the stirring movement and the movement of the rust cleaner, no consumption of external energy occurs, so that the energy consumption is very low, since it is sufficient to move the carburetor ring 19 or the rust cleaner 27 for a few seconds approximately every half hour.
  • the size of the burnup can be changed by at least 75% between the minimum and the maximum, so that the system can be operated for hot water preparation even in summer.
  • combustion duct 11 can be arranged over a further area with respect to the primary air opening 18. This allows the system to be better adapted to the prevailing circumstances.
  • the grate 15 rotates, whereas the grate cleaner 27 generally stands still.
  • the pot-shaped grate 15 is connected in a similar manner to the carburetor ring 19 by means of driving rods 30, as is shown for the grate cleaner 27 in FIG. 1.
  • the driving rods 30 slide longitudinally displaceably in vertical grooves 39 on the circumference of the carburetor ring 19, so that a height adjustment of the grate 15 with respect to the carburetor ring 19 is possible.
  • the grate 15 is in this case rotatably suspended from the central rod 24, the upper end of which is suspended on a housing 46 of the worm gear 47 by means of a friction clutch 64.
  • the rod 24 is fastened to a friction disk 40, which lies between two friction plates 41, which are supported by springs 42 are pressed against each other.
  • the springs 42 surround columns attached to the top wall of the housing 46, which at the same time secure the two friction plates 41 against rotation.
  • the grate cleaner 27 consists of a horizontal cross shaft 43 attached to the rod 24, around which two flaps 44 can be pivoted, each of which carries at its lower end a horizontal grate cleaner rod 28 which sweeps over the openings 15 of the grate 15 which widen downwards.
  • the rust cleaner flaps 44 can pivot about their horizontal transverse shaft 43 until the obstacle is removed again. In the event of a permanent obstacle, however, the cross shaft 43 is taken along by the flaps 44 for rotary movement of the grate 15 as soon as the frictional resistance between the friction disk 40 and the two friction plates 41 pressing it in is overcome.
  • the friction plates 41 there is an adjusting nut 45 on the outside of the hollow shaft 21 on a threaded part of the hollow shaft 21, which can be supported on the housing 46 of a worm gear 47, via which the hollow shaft 21 is driven by the geared motor 22 for rotary movement.
  • a height adjustment of the hollow shaft 21 and of the carburetor ring 19 suspended on it by means of the struts 20 is thereby possible.
  • the struts 20 carry spring tines 35 pointing obliquely upward into the supply shaft 4.
  • the supply shaft 4 is delimited by a sheet metal housing 5 which is seated within a clamping ring 48 which has several sectors of a ring 49 made of mineral material, e.g. B.
  • a vertical smoldering gas channel 55 runs in the supply shaft 4 from the uppermost region of the supply shaft 4 to a horizontal channel 56 in the concrete jacket 9.
  • This channel 56 leads from an inlet opening 57 for fresh air to the combustion chamber 10 above the grate 15.
  • this channel 56 there is a heat shield plate 66.
  • a duct 58 branches off from the duct 56, through which the fresh air is fed to the ash chamber 16 below the grate 15, the fresh air being heated by the heat shield plate 66.
  • the combustion chamber 10 is accessible through the channel 56.
  • the concrete jacket 9 is surrounded by an insulating jacket 59, which in turn is surrounded on the outside by a cavity 60.
  • This cavity 60 has an inlet opening 61 for fresh air and is connected to a recess 62 which is formed above the combustion channel 11 in the stone ring 49.
  • This recess 62 is connected to the combustion channel 11 via a vertical channel 63.
  • the flap 33 is provided, which is adjusted by the draft regulator 3 of the boiler. A similar regulation can be provided for the air inlet opening 61.
  • primary air can be supplied both to the area above the grate 15 and to the area below the same, e.g. B. if a small opening, not shown, is provided in the heat shield plate 66. Since the lowest area of the carburetor ring 19 is close to the combustion chamber 10, the carburetor ring there is very hot, so that the combustible material is already igniting on it. The carburetor ring 19 becomes colder towards the top, but degasses the material. In the uppermost area of the carburetor ring 19 and in the area of the stone ring 49, the fired material is dried and, if appropriate, also degassed.
  • the embodiment according to FIG. 4 is particularly suitable for large systems because of the large cross section of the storage shaft 4.
