Definitions

  • the invention relates to a burner arrangement for heating or for keeping warm, in particular G confusestrahlschutz- and / or Tauchausgussurbanen particular a continuous casting.
  • the molten liquid metal is usually brought by means of a pan to the casting stand of a continuous casting plant.
  • the molten metal flows out of the ladle into a distributor through a pouring-beam protection, such as a shadow tube.
  • the metal flows through a submersible nozzle, such as a dip tube, in the mold of the continuous casting.
  • Immersion tube and possibly shadow tube are preheated before pouring, usually not in the casting operation.
  • a burner with fossil fuels, such as natural gas, and with oxygen carriers, such as air operated.
  • conventionally commercially available burners are used which heat a container in which the dip tube or the shadow tube is arranged.
  • a burner is used, which is the shadow tube or the immersion tube heated directly and without the interposition of a container with the flame.
  • Such burners have become known, for example, from JP 61262455 A, EP 0 775 543 B1, EP 0 495 764 B1 and KR 1020050114398 A.
  • the electric heating has been disclosed by JP 10118746 and DE 196 51 533 C2.
  • the electric heating has the disadvantage that the efficiency is particularly unfavorable, so that the primary energy demand is relatively high and thus the process is not very economical.
  • the object of the invention is to provide a burner arrangement for heating or for keeping warm, in particular of G confusestrahlschutz- and / or Tauchausguss adopteden particular a continuous casting, which achieves improved utilization of the energy used, a reduction in the emission of CO 2 and high availability of the system. It is another object of the invention to provide a method for advantageously controlling a burner assembly.
  • the object with regard to the burner arrangement is achieved with a burner arrangement, in particular for heating or keeping warm, in particular Gellostrahlschutz- and / or Tauchausguss droveen a continuous casting with a particular shadow tube or a dip tube receptive container, wherein the wall of the container at least partially formed by at least one pore burner is.
  • the pore burner preferably has a plurality of pore burner segments. These are then connected to each other to the pore burner or formed in one piece or in one piece.
  • the pore burner segments of the pore burner form rings and / or rows viewed in the axial direction. Furthermore, it is advantageous if the pore burner consists of pore burner segments, with a plurality of segments forming rings or rows in the circumferential direction. In one embodiment of the invention, it is expedient for the pore burner segments of the pore burner to be arranged hexagonal or octagonal in the circumferential direction.
  • the container has a bottom and / or a lid, which consist of a bottom-side and / or lid-side plate.
  • the pore burner segments are each supplied with fuel by means of supply lines, in particular from radially outside.
  • the leads from the segments can be guided radially outward and possibly extend axially in a further supply line section.
  • the supply lines are supplied with fuel via a common supply line. It may be expedient if the supply line or the supply lines is substantially annular and is in communication with supply lines. In this case, the ring must not be completely closed, the ring can also be closed advantageous.
  • pore burner segments are switched on or off depending on the desired heating intensity or heating power. It may be advantageous if the segments are switched on or off, which are at least alternately distributed at the beginning of the pore burner. As a result, it can be advantageously achieved that operated and switched-off segments are distributed uniformly over the circumference. It is also expedient if segments are switched on or off, which are viewed in the axial direction of the pore burner in each adjacent or more distant other rings or rows of pore burner segments are arranged. This can advantageously be achieved that powered and disconnected
  • O segments are evenly distributed over the axial length of the burner assembly.

  • Fig. 4 is a sectional view in the horizontal direction of a burner assembly according to the invention a dip tube.
  • the burner assembly 1 shows a sectional view of a burner assembly 1, in particular for heating or for keeping warm Gellostrahlschutz- and / or Tauchausgussurbanen particular from a continuous casting.
  • the burner assembly 1 in this case provides a burner 3 arranged around a dip tube 2 which, according to the invention, is designed as a pore burner.
  • the pore burner has the advantageous property that it allows combustion of a gas-air mixture in a porous structure or cell as a gas burner, which can be achieved virtually without the formation of an open flame. As a result, a flameless, volumetric combustion of the Gas-air mixture achieved. In this case, a combustion in the porous structure is thus achieved, so that after the introduction of the gas-air mixture as a reaction product, an exhaust gas stream is generated on the output side.
  • the pore burner 3 shown in FIG. 1 is composed of several segments.
  • the individual segments 3a, 3b, 3c, 3d are arranged viewed in the axial direction of the dip tube and each have their own supply line 4 of the fuel, the oxygen carrier or the fuel-air mixture, or they each have a supply line for the fuel and for an oxidizer, such as air.
  • the air or oxygen can also be introduced or blown into the pore burners via a blower.
  • the dip tube is furthermore arranged in an advantageously thermally insulated container 5, which is advantageously formed by the two bottom-side and cover-side plates 6, 7 and on its outer circumference the wall 8 is formed by the segments 3 a, 3 b, 3 c, 3 d of the pore burner 3 becomes.
  • the segments are arranged side by side with a small joint spacing, so that an arrangement of the pore burners which is multi-row in section is formed.
  • the segments 3 a, 3 b, 3 c, 3 d of the pore firing 3 are arranged essentially annularly or hexagonally or octagonally around the dip tube 2. This results in a quasi-tubular arrangement of the pore burner segments around the dip tube.
  • the pore burner 3 generates a hot exhaust stream 9 and heat radiation 10 which are directed to the dip tube to heat it, to heat it or to temper it at the temperature.
  • the hot exhaust gas enters the heating chamber of the interior of the container 5 at a relatively low speed, which causes a homogeneous temperature distribution in the interior of the container 5 and thus counteracts stratification.
  • the dip tube can also be heated very well.
  • the formation of the pore burner as a substantially annular or tubular arrangement, wherein the arrangement of individual segments of pore burners is composed. As a result, it can be advantageously controlled that individual segments or rows or rings of segments are switched on or off independently of one another or individual segments are switched on or off independently of one another.
  • all pore burner segments can be switched on or individual segments can be switched off. It can be advantageous if segments are switched on or off, which are distributed at least alternately at the beginning. It can also be advantageous if the annular segments which are viewed in the axial direction of the dip tube are alternately switched on or off.
  • Figures 3 and 4 show an embodiment in which a shadow tube 20 is provided with a burner assembly 21 according to the invention.
