Definitions

  • the invention relates to a burner, in particular for use in a rotatable drum of an incinerator for flowable waste materials which can be conveyed by a pump, with a lance for introducing the fuel, at the end of which a nozzle is arranged.
  • Wastes such as contaminated solvents, contaminated oils, dye sludge, faulty batches from production, etc.
  • rotary drum furnaces for procedural reasons.
  • the waste materials are added via burners, lances or e.g. also by the barrel, the feed units being installed in an end wall of the furnace.
  • This end wall is permanently installed and is usually only connected to the rotating rotary drum furnace by a gas-tight sliding seal.
  • Waste incineration plants using this rotary drum furnace method are usually designed according to the expected thermal load of the rotary drum furnace.
  • the calorific value of pumpable waste liquids can fluctuate within wide limits, the heat released when these liquids are burned also fluctuates within wide limits and thus the thermal load on the rotary drum.
  • a furnace of the type mentioned above is known, which is designed for smaller plants and is designed as a combined combustion and melting furnace for solid, doughy and liquid waste materials with a drum diameter of less than 2 m.
  • the device for placing barrels in one end wall and the burner for the flowable (liquid or pasty) waste materials that can be pumped were arranged in the other end wall, the two end walls not being firmly connected to the drum and the drum is pivotable about its axis.
  • the burner in turn, is designed so that it can be pushed into the furnace or pulled out of it along its longitudinal axis. This means that it can always be brought close to the waste materials to be incinerated.
  • the present invention is based on the object of developing a burner which is particularly suitable for the operation of such a furnace, by means of which, in addition to the fuel for a pilot flame, further ones for opening maintenance or improvement of the combustion necessary media can be introduced and is protected as well as possible against mechanical and thermal loads.
  • FIG. 1 an end wall 1 of a burner nozzle of a drum of an incinerator, not shown, is only partially shown. An opening 2 of this end wall 1 passes through a burner 3, held by one, a seal 4 attached ring flange 5.
  • the burner 3 consists essentially of a nozzle 7 arranged at the end of a lance 6, a first casing 8, which is described in more detail below, which surrounds the lance 6 and the nozzle 7 in a coaxial and fixed arrangement thereof, and a second, in The jacket 9 described in more detail below, which encloses the first jacket 8 in an arrangement that is fixed relative to it.
  • the first, inner casing 8 consists essentially of two tubular and coaxial casing parts 10 and 11, which are not connected to one another at the end adjacent to the nozzle 7, so that this first casing is open on the furnace side (it is not water-cooled).
  • the second, outer casing is water-cooled, it essentially consists of an outer tubular casing part 12 and an inner casing part 13, which are connected to one another at their two ends to form a container for the water, each by a (not designated) front part. Stubs 14 and 15 for the supply and discharge of cooling water are provided.
  • the two jackets extend substantially the same length into the furnace and the lance 6 is arranged therein so that the nozzle 7 is enclosed by them. The lance 6 and the nozzle 7 are thus protected against mechanical and thermal effects of the furnace by two jackets.
  • each water pipe 16 is arranged parallel to the axis, which at their end adjacent to the nozzle 7, each with an atomizing nozzle 17 and at their other end, each with a nozzle 18 for the supply of Water are provided. With the help of these water pipes 16 and through these atomizing nozzles 17, water can be injected and atomized into the furnace will.
  • the burner air required for operating the burner is introduced from a pipe 32 through the remaining space between the two jacket parts 10, 11 of the first, inner jacket 8 in the vicinity of the nozzle 7 and approximately coaxially therewith into the furnace.
  • the combustion air required for the combustion of waste for example, is between the two jackets 8 and 9, i.e. inserted between the jacket parts 10 and 13 in the furnace. This separate introduction of the burner air and the waste combustion air is a reason why these two air feeds are arranged eccentrically to one another; there are fewer interactions between the two air flows.
  • the lance 6 and the first casing 8 are arranged coaxially to one another and eccentrically parallel to the second casing 9.
  • the offset of the axis A of the lance 6 and thus of the nozzle 7 is approximately 30-80 mm.
  • a lance 20 of a pilot burner is arranged in the space 19 between the two jackets 8 and 9 or between the outer jacket part 10 of the first jacket 8 and the inner jacket part 13 of the second jacket 9.
  • Other pipes, not shown, can also be arranged in the space 19 mentioned, for example for sludge, extinguishing water and the like.
  • the combustion air required is supplied to the furnace via the pipelines 21 and, as already indicated, by the mentioned space 19 fed through.
  • Fig. 4 which shows a view of the rear of the burner 3, as well as in Fig. 1, the lines 22, 23 and 24 serving for the supply of fuels and water and optionally additives can also be seen.
  • the point 25 can also be seen where a photocell can be arranged to monitor the burning process.
  • the optical path from the inside of the furnace or from the nozzle 7 to this photocell is created in that the inner jacket part 11 of the first jacket 8 has a corresponding bulge 26 (FIG. 3), deviating from the shape of a cylindrical tube.
  • the inner jacket part 11 of the first jacket 8 is provided with a flattened area 27 in the area of the air supply (FIGS. 1 and 3) which merges into the tubular shape (FIG. 2) via an inclined surface 28 (FIG. 1) .
  • the inner casing part 13 of the second casing 9 does not extend as a single part over the entire circumference of the casing. Thanks to the exzentrsichen arrangement, both the first shell 8 and the lance 20 of the pilot burner with respect to the second - jacket, it is possible the inner shell part 13 of the second shell 9 to the welding points 29 and 30 with the outer shell portion 10 of the first sheath 8, or to be welded with the lance 20 of the pilot burner. In order to complete the elongated space between the two sheaths 8, 9, the lance 20 is also welded to the outer sheath part 10 of the first sheath 8 at the welding point designated 31. This saves material and weight.
  • Such a burner can be used very flexibly and is largely secured against damage. Any medium can be brought to the place where it is needed for combustion. This burner should not only be used in rotary drum furnaces, but is also suitable for use in any other furnace.
  • the method according to the invention describes the particular advantages of introducing the burner air and the combustion air together with a burner.
