Definitions

  • the invention relates to a device for the gasification of fine-grained to dust-like fuels in the fly dust cloud with oxygen and / or air and optionally water vapor in a gasification reactor, which has at least two burners arranged in one plane in the side wall of the reactor.
  • the autothermal gasification of fine-grained to dusty fuels with an average grain size of approx. 50 ⁇ m in the fly dust cloud with oxygen and / or air and possibly water vapor has been known for a long time under the name Koppers-Totzek process.
  • the fuel to be gasified and the reaction media are blown into an empty gasification reactor via the burners and converted there at temperatures above the slag melting point by partial oxidation into a raw gas, which can be worked up either to synthesis gas or to fuel gas.
  • the fuel can be fed to the burners via screw conveyors, which permit good quantity control.
  • the fuel is first fed through the screw conveyor to a so-called mixing head and from there through the flow of the gaseous or vaporous reaction media via the burner heads into the gasification reactor blown in.
  • a so-called mixing head In recent times, however, there has been a tendency to further develop this process in such a way that the gasification can be operated under increased pressure between 10 and 100 bar, preferably between 25 and 45 bar.
  • the print version of the Koppers-Totzek process is referred to as the PRENFLO process.
  • screw conveyors are not very suitable for transporting the fuel to the burners. Instead, pneumatic conveying with a preferably inert conveying gas is used.
  • Gasification in the dust cloud requires an exact allocation of fuel and reaction media.
  • High throughput gasification reactors are preferably equipped with two or more burners. For an optimal operating result, the most uniform and uniform fuel supply to all burners of the gasification reactor must be ensured. In the normal case, the fluctuation range of the flow rate density in the fuel supply should be only approx. ⁇ 2%.
  • the invention is therefore based on the object of designing the device of the type mentioned in such a way that a uniform and uniform fuel supply to all burners of the gasification reactor is ensured.
  • the device serving to solve this problem is to be characterized at the same time by the least possible outlay in terms of apparatus and is also intended to allow the greatest possible design freedom with regard to the line routing for the fuel supply to the burners.
  • the device of the type mentioned at the outset which is used to achieve this object is characterized in that all burners of the gasification reactor are supplied with fuel from a single supply container via a distributor, the lines for the fuel supply from the distributor to the individual burners having a different length and / or have cable routing.
  • all burners of the gasification reactor are supplied with fuel from a single supply container.
  • the gasification reactor has more than two burners.
  • the gasification reactor is equipped with more than two burners, which are preferably arranged in pairs. If the number of burners is greater, for example> 6, then it is also possible to dispense with the arrangement of the burners in pairs. Rather, these can then be arranged uniformly distributed over the entire circumference of the gasification reactor in one plane.
  • the fuel supply to the burners via a single supply container means significant savings in plant and operating costs. It must be taken into account here in particular that the necessary conveying and sluicing devices must also be assigned to each supply container, by means of which the fuel coming from the processing plant is brought to the required operating pressure and transferred to the supply container.
  • the lines for the fuel supply to the burners are connected to a distributor, which runs from the supply container with fuel is supplied.
  • This distributor is arranged vertically and as close as possible under the outlet of the feed container and connected to it by a rigid delivery line, with the addition of delivery gas in this line being dispensed with.
  • four lines for the fuel supply to the burners go from the distributor. If, on the other hand, the number of burners in the gasification reactor is greater than four, two or - with a correspondingly large number of burners - more than two distributors can be provided, the second and each further distributor being arranged in a line for the fuel supply from the first distributor to the burners .
  • these additional distributors also have lines for the fuel supply to the burners assigned to them.
  • the device shown in Fig. 1 consists of the supply container 1, in which the fuel to be gasified is located.
  • the distribution container 1 is under pressure so that a pneumatic transport of the fuel via the downstream lines to the burners 3 to 6 in Gasification reactor 2 is possible.
  • the fuel is withdrawn from the supply container 1 via the delivery line 7 and reaches the distributor 8, which is arranged relatively close below the funnel-shaped outlet of the supply container 1.
  • both the feed container 1 and the distributor 8 can be arranged at some distance from the gasification reactor 2.
  • the lines 9, 10, 11 and 12 for the fuel supply to the burners 3, 4, 5 and 6 extend from the distributor 8. As shown schematically in the figure, these cables have different lengths and routings.
  • Changes in the output of the gasification reactor 2 can be made by changing the setpoint of the differential pressure controller 20 accordingly.
  • the differential pressure regulator 20 regulates the pressure difference between the feed container 1 and the gasification reactor 2.
  • the throttles 13 can be replaced by suitable control valves of conventional design, which make it possible to set the fuel flow to each burner the same or different. In this case, the differential pressure between the feed hopper 1 and the gasification reactor 2 is kept constant.
  • FIG. 1 shows only the parts of the system necessary to explain the invention in a schematic representation.
  • the constructive design of these parts of the system that is to say in particular the feed container 1, the gasification reactor 2, the distributor 8 and the burners 3, 4, 5 and 6, was not discussed in detail since this is not the subject of the invention.
  • the supply container 1 must also be equipped with appropriate devices for the supply of fuel and for keeping the pressure constant, which are also not shown in the figure. This can also be units known for this purpose, e.g. Pressure pot conveyor or lock bunker, act.
  • the structural details of the throttle 13 can be seen in the illustration in FIG. 2, which shows a section through such a throttle.
  • the throttle consists of a cylindrical jacket 14, the outer diameter of which corresponds approximately to the flange diameter of the pipeline in which the throttle is installed. Since the throttle is flanged into this pipeline, it is also advantageous if the cylindrical jacket 14 from the the same metallic material as the pipeline. At its front and rear ends, the cylindrical jacket 14 has an inner diameter d 1 which corresponds to the inner diameter of the connected pipeline.
  • the lining 15, which consists of a wear-resistant material such as ceramic, and which can optionally be composed of several parts, is arranged within the cylindrical jacket 14. The shape of the lining 15 is such that it can accommodate the displacement body 16.
  • This is also made of a wear-resistant material and is fastened within the lining 15 by means of the webs 17 in such a way that an annular gap 18 is formed between the lining 15 and the displacement body 16, which gap corresponds to the height of the webs 17.
  • the displacement body 16 has a shape in which its two ends taper conically, while a cylindrical part is located in the middle.
  • the sealing rings 19 serve to seal the lining 15 within the cylindrical jacket 14.
  • the lining 15 is pressed into the jacket 14 by the projection 21 on the flange of the pipeline to be connected.
  • the pressure loss in the throttle depends on the width and length of the annular gap 18 and the fuel / conveying gas velocity in the annular cross section of the gap 18, which is greater than in the pipeline with the diameter d 1.
  • the calculation of a throttle that proves to be suitable under the conditions of so-called flow promotion is based on experimentally determined data with a Accuracy of ⁇ 5% possible.
  • the installation of the throttle also has the advantage that coarser particles in the fuel, such as fibers, leading to blockages are already held in place and cannot first reach the burner, from which they would be far more difficult to remove.
  • care must be taken to ensure that their effect is not so great that the fuel supply to the burner is disrupted as a result of the line being blocked.
