Definitions

  • the invention relates to a device for injecting combustion media, such as fuel or oxidant, in a metallurgical treatment room, with one or more supply channels for a first combustion medium and a plurality of supply channels for a second fuel medium, which open in an orifice region of the device.
  • combustion media such as fuel or oxidant
  • Burners or lances for injecting fuel and / or oxidant into a metallurgical treatment space are known.
  • a lance for injecting fuel and / or oxygen into a melting furnace which has a central supply line for fuel and a coaxially arranged supply line for oxygen.
  • a multiplicity of obliquely extending feed channels leads from the oxygen feed line into the fuel feed line. Through these supply channels at least a portion of the oxygen is introduced into the mouth portion of the fuel supply line and mixed with the fuel. The mixture is introduced into the furnace and forms a flame there.
  • the object of the invention is therefore to provide a device for injecting fuel and oxidant into a metallurgical treatment space in which the treatment chamber is more uniformly exposed to the flame.
  • the feed channels for the second combustion medium are charged with the fuel medium via the supply lines separated from each other by flow.
  • the flow rate passed through each of the supply lines can also be individually adjusted during operation of the device.
  • the respectively suitable setting of the flow rates can be determined empirically, for example.
  • the supply lines are in flow communication with a supply unit for the second combustion medium.
  • the supply unit can be, for example, a tank or a pipeline from which the supply ducts are supplied centrally with the second combustion medium.
  • the supply lines are preferably equipped with valves for limiting the flow, which are in data communication with a control unit, by means of which the flow rates through the individual supply lines can be controlled.
  • valves are motor-operated valves or slides, in particular ball valves, or solenoid valves.
  • valves are each provided with a bypass in order to ensure a minimum flow through the supply line.
  • a particularly advantageous embodiment of the invention provides a geometry of the device according to the invention in the form of an axial feed channel for the first fuel medium, which is coaxially enclosed by a feed for the second fuel medium, which divided at least on their rear portion seen in the mouth region in flow-separated feed channels is.
  • the feed for the second combustion medium is preferably subdivided into two feed channels which are separated from one another by oppositely disposed flow separators. This allows a two-dimensional change in position of the flame along a plane in the treatment room.
  • this embodiment allows in particular a pivoting of a flame generated in the combustion chamber of the combustion media in the treatment room.
  • a further embodiment of the invention provides that the feed for the second combustion medium is subdivided into at least three feed channels, which are separated from one another by flow separators arranged at preferably equal angular intervals.
  • this embodiment allows a three-dimensional position change, in particular a rotation of a flame generated in the combustion chamber of the combustion medium in the treatment room. If more than three supply channels are provided, the flame geometry can be more selectively influenced by a variation of the different flow rates.
  • the object of the invention is also achieved by a method for operating the device described above, in which a first combustion medium is introduced through a supply channel for the first fuel and a second fuel medium through supply channels for the second fuel medium in the treatment chamber, in which the first fuel reacts with the second combustion medium to form a flame, wherein the geometry of the flame is changed during the combustion process by a variation of the flow rate through the supply channels.
  • the flame is thereby pivoted or rotated by a periodic sequence of changing flow rates in the supply lines. This achieves a uniform admission of the treatment chamber with the flame and thus the production of a uniform heat distribution in the treatment room.
  • the device 1 is a fuel-oxygen burner.
  • the device 1 comprises a central feedthrough 3 for a starting gas, which also serves as an observation channel for a UV monitoring unit 4 connected to the feedthrough 3.
  • a fuel supply 5 is arranged, which serves to introduce a fuel into a metallurgical treatment chamber 6.
  • Coaxial around the fuel supply 5 around an oxygen supply 8 is arranged.
  • the oxygen supply 8 is subdivided by means of partition walls 9, 10 which are arranged over virtually the entire longitudinal extension of the oxygen supply 8 into two oxygen supply channels 12, 13 which are separated from one another by fluid flow and into which separate supply lines 14, 15 each open.
  • the supply lines 14, 15 are connected via a three-way valve 17 to an oxygen main line 18 via which oxygen is supplied from a storage container (not shown here), for example an oxygen tank.
  • a storage container not shown here
  • the device 1 can be equipped with cooling in a known manner and therefore not shown here.
  • liquid or gaseous fuel in the exemplary embodiment natural gas, via a fuel port 20 in the fuel supply 5 and from there in an amount of 20 to 80 m 3 / h and at a speed in the range of 15 - 50 m / s introduced into the treatment room 6.
  • Oxygen is likewise introduced into the treatment chamber 6 via at least one of the oxygen supply ducts 12, 13, wherein the flow through the supply ducts 14, 15 and thus through the oxygen supply lines 12, 13 can each be precisely adjusted by a corresponding setting on the three-way valve 17 , Oxygen and fuel mix within the treatment chamber 6 in the apron of the burner mouth 21 via a Zündgasan gleich 22 a pilot gas is introduced through the passage 3 in the treatment chamber 6, which for the ignition of the fuel-oxygen mixture and the subsequent formation of a flame before Burner mouth 21 provides.
  • the flame forming in front of the mouth 21 of the burner can be pivoted within the treatment space 6 along a vertical plane.
  • the flow ratio for the amounts of oxygen passed through the lines 14,15 and the oxygen channels 12,13 is changed.
  • the Alternating supply of the oxygen channels 12,13 with a large or small amount of oxygen the flame can also be moved periodically up and down.
  • the device 1 thus provides a cost-effective way to continuously change the position of the flame within the treatment chamber 6 by pivoting, without the need for this a complex structural change in the wall of the treatment chamber 6 or a pivotal mounting of the burner.
  • the device 30 differs from the device 1 only in the structure of the oxygen supply 32. While the oxygen supply 8 is divided in the device 1 into two flow channels 13,14, the oxygen supply 32 by means of two flow separators in the form of at least substantially gas-tight partitions 33rd , 34,35 divided into three oxygen supply channels 36,37,38.
  • the oxygen supply channels 36, 37, 38 are each in fluid communication with supply lines 39, 40, 41.
  • the supply lines 39, 40, 41 are connected via a distributor 42 to an oxygen main line 43.
  • each flow-controlling valves for example, solenoid valves 45,46,47 are provided in these, which can be controlled by a central control unit 49 according to a predetermined program.
  • the solenoid valves 45, 46, 47 are each provided with a bypass 51, 52, 53 in order to ensure a minimum flow throughflow in each of the supply lines 39, 40, 41 even in the case of a closed solenoid valve.
  • fuel for example natural gas
  • oxygen is introduced from the main oxygen line 43 via the supply lines 39, 40, 41 into the treatment chamber 6 via at least one of the oxygen supply channels 36, 37, 38.
  • a flame forms in the treatment chamber 6 in front of the burner mouth 21.
  • the oxygen streams guided through the oxygen channels 36, 37, 38 are set by the control unit 49 by driving the solenoid valves 45, 46, 47.
  • An asymmetry in the guided through the oxygen supply channels 36,37,38 oxygen flows leads to a corresponding asymmetry of the flame in the treatment chamber 6.
  • a rotation of the flame in the treatment chamber 6 succeeds.
  • the flame propagation and the rotational speed can be freely set in a wide range and individually adapted to the respective treatment room.
  • the devices 1,30 can be installed without extensive structural measures in existing treatment rooms. They are inexpensive in construction and easy to use.
