Definitions

  • the invention relates to a device for burning, in particular, pressed straw in a burner, which is fed to the combustion device in compressed form to form large bales.
  • bales are fired in large boilers into which air is injected to promote combustion.
  • efficiency of the combustion and thus of the energy production is still not entirely satisfactory. This is mainly due to the fact that with these bales a flawless combustion is only achieved in the area of the surface, whereas a smoldering fire occurs inside these large bales, which ultimately leads to incomplete combustion and excessive flue gas development.
  • the latter requires additional precautions to keep the emission values of the exhaust gases within the restrictive values for reasons of environmental protection.
  • the object of the invention is to further improve a combustion device for particularly compressed straw bales in such a way that simple measures ensure the most complete and thus largely residue-free combustion of such bales with high efficiency.
  • the compressed large bales are thus dissolved in a separate work process before combustion, which is done by a tearing device.
  • This has the advantage that there is a uniformly processed combustion material so that different combustion zones do not occur in certain areas. Rather, it is ensured that, as a result of the dissolution of the large bales, a very even combustion of the fuel is achieved, which also causes only minimal residues.
  • the efficiency of the burner is then correspondingly high.
  • the fired material thus prepared can be fed directly into the burner, but it is advisable to recompress it so that the previously dissolved straw material is compressed and portioned into the burner.
  • the good and complete combustion of the compressed material is then guaranteed because the fuel is immediate split up before insertion into the burner, ie was dissolved and immediately fell apart in the burner. So-called embers and the like no longer occur.
  • an extremely simple, robust and easy-to-use construction which comprises a container with a tearing device arranged therein with a downstream portioning device.
  • the tearing device expediently consists of a number of knife rollers on which the bale to be broken rests.
  • the processed straw falls through a discharge opening on the bottom of the container into a conveyor trough and from there into the burner.
  • a piston provided with a scoop is reciprocally guided in the conveyor trough, by means of which the straw that has fallen into the conveyor trough is compressed into a feed pipe, from where the straw is then introduced into the burner under high pressure by means of a plunger .
  • the bottom of the container has two converging inclined surfaces so that the bottom has a substantially V-shaped cross section.
  • the straw is automatically fed to the discharge opening and the straw bale is always held in the center of the container. Due to the fact that the knives of adjacent knife rollers are offset from one another, the adjacent knife rollers engage in one another, so that a very fine dissolution of the pressed straw is achieved.
  • the straw and binding wire are prevented from being wound up on the knife rollers. At the same time, the straw bale is further torn open.
  • the drive of the knife rollers expediently switches off automatically when a straw bale is inserted into the container, so that there is no risk of injury.
  • a metering roller arranged above the discharge opening promotes the discharge of the processed straw from the container into the conveyor trough.
  • a fender assigned to the piston in the conveyor trough prevents straw from falling behind the piston in the end position of the piston, in which this closes the feed tube to the burner, and can impair the backward stroke of the piston.
  • the mudguard which closes the discharge opening and thus the container from the burner, provides protection against a flashback.
  • a further safeguard is given in that the piston closes the feed pipe leading to the burner in its end position.
  • Other safety options include a sprinkler system provided on the feed pipe and a swivel flap articulated on the combustion pipe, which also prevents a flashback.
  • the interior of the container is expediently dimensioned such that the large bale cannot squeeze in the interior in any position, but always rests on the knife rollers.
  • Photocells in the container walls indicate when the straw bale processed by the knife rollers reaches a certain level falls below, then a conveyor located outside the container is operated to feed another straw bale due to the signal emitted by the photocells. As soon as this straw bale has been inserted into the container, the contact of the photocells is interrupted, the conveyor being switched off again by the signal triggered in the process.
  • the device comprises a tower-like container 1, on the bottom 2 of which the tearing device, generally designated by the reference number 3, is arranged. Furthermore, the container 1 comprises a feed opening 4 in a side wall, which is only shown schematically. Another feed opening 5 can be provided on the roof of the container.
  • the container is expediently equipped with two supply openings 4, 5, but the container can also be provided with only one of the supply openings 4, 5 as required.
  • the container 1 further shows a plate conveyor 6 on which the straw bales are fed to the container 1. If the S trohballen the container are supplied through the supply port 5, the plate conveyor is of course 6 is aligned so that the bales of straw can be conveyed to the height of the container roof.
  • the use of the feed opening 5 is particularly advantageous if other materials to be crushed, which are to be entered as bulk material, such as wood chips and the like.
  • a conveyor trough 8 which will be described in more detail below, via which the straw dissolved by the tearing device is fed to a feed pipe 9, which leads to the straw burner 10 shown in FIG.
  • the straw burner 10 is located in a boiler 11 which has smoke extraction channels 12.
  • the straw fed through the feed pipe 9 is pressed into the straw burner, which is blown or pressurized with air via a blower 13 in order to promote the combustion of the straw.
  • the burner 10 also includes a water jacket 14 which is intended to avoid overheating of the burner.
  • the ripping device 3 comprises a number of knife rollers 15 arranged next to one another.
  • Each knife roller has several rows of knives 16 arranged at a distance over the circumference (cf. certain interlocking between the individual rollers is guaranteed. In this way, a very good resolution of the straw bale to be torn is achieved.
  • the knife rollers 15 are expediently arranged parallel to one another and extend over the entire length of the container base 2, wherein they also extend essentially over its entire width. This means that almost the entire floor is covered by the knife rollers. There is therefore no dead space where larger parts of the straw bale can accumulate, so that a complete dissolution of the straw bale put into the container is ensured.
  • the bottom 2 is expediently formed by two inclined surfaces 2a and 2b converging to a center line 17, two knife rollers each being arranged on an inclined surface 2a and 2b.
  • this training has the advantage that the processed straw is automatically conveyed to the discharge opening 7 and, on the other hand, a certain centering of the straw bale entered into the container is achieved, so that it is not displaced into a corner of the container.
  • the container is dimensioned so that a tilting of the S trohballens does not occur within the container and so that the straw bale always rests on the rotating knife rollers 15 due to its weight.
  • the cutter blocks 15 are controllable in its rotational direction so that adjacent blade rolls rotate in opposite directions or the same direction or only a part of the rollers counter-l ä u fig or rotates in the same direction. This is expediently carried out by a program control, it also being possible to carry out changes in the direction of rotation. If necessary, a change in velocity of the circulating measure- ser rollers 15 are possible. All this has the purpose of, on the one hand to increase the tearing action, and to prevent other hand, a winding of the dissolved straw to the cutter blocks of n. The changes in direction of rotation or rotary encoders sch windiness may be made periodically.
  • a metering roller 21 is arranged above the discharge opening 7 and is provided with wings or blades 22. The straw is pressed out of the container 1 into the chute 30 by means of this metering roller.
  • an elongated fender 23 is fastened, which serves to close the discharge opening or the chute 30.
  • the fender 23 With the forward stroke of the piston 18, the fender 23 is pushed in front of the discharge opening 7, so that the container 1 is closed off from the conveyor trough.
  • This has two effects. On the one hand, this prevents straw from getting out of the container behind the piston 18 during the forward stroke of the piston 18, which can lead to obstructions of the piston during the reverse stroke.
  • the mudguard 23 requires additional protection against a flashback from the burner, since the discharge opening 7 and thus the container are closed off from the conveyor trough and thus also from the feed pipe 9.
  • a further safeguard is achieved in that the piston 18 is always in its end position shown in dash-dotted lines in FIG. This also prevents a flashback from the burner into the container. The piston 18 only moves back into the position shown by the solid line when a further batch of straw is to be fed to the burner.
  • the supply of straw bales which are usually pressed into a round or square bales and in the case of a round bale having a diameter of about 180 cm, controlled by schematically illustrated photocell 27 which ne angeord- in the side walls of the container 1 are t.
  • a certain level is determined by the photocells.
  • the signal from the photocells 27 results in a control signal for the plate conveyor 6, which then conveys another bale into the container 1. As soon as the new bale is introduced into the container, the drive of the Pl is turned off atten barkers 6 by a further signal of the photocells 27th
  • the roof of the container 1 to form the feed opening 5 is designed as a folding roof, for which purpose the roof is divided into two hinge-like roof halves 29a, 29b.
  • the roof half 29 b is guided over rollers on a running rail at the upper edge of the container 1.
  • the knife rollers 15 are still coupled to the door or the Kl app roof of the container 1 such that the knife rollers 15 stand still when the door or the folding roof is open, so that there is no risk of injury.
  • one bale is inserted into the container 1 and there due to the action tearing of the tear device.
  • the tearing device is shown in the form of knife rollers 15, other chopping devices or cutting devices can also be used if only the straw bale including the existing packaging cords can be shredded in a suitable manner.
  • the straw prepared by the tearing device falls into the conveyor trough and is compressed there by the piston against the feed pipe and finally entered into the burner under great pressure by means of a stamp.
  • the feed pipe 9 is expediently designed in such a way that it widens towards the burner, so that the straw can expand a little bit shortly before the oven and thus the oxygen can get into the straw better. This favors the burning of the straw inside the burner.
