Definitions

  • the invention is directed to a gas burner for combustion of fuel gases with oxygen comprising a Primärgasdüse and secondary gas nozzles, which are connected to a common central supply line.
  • a gas burner for combustion of fuel gases with oxygen comprising a Primärgasdüse and secondary gas nozzles, which are connected to a common central supply line.
  • the obliquely downward non-horizontal openings of the primary gas nozzle are aligned so that the gas jet is directed to a point of a center line between two Sekundärgasdüsen, and the center line is defined as an imaginary line parallel to the axis of rotation of the Primärgasdüse and centrally between two adjacent secondary gas nozzles runs.
  • stepped gas burners In the combustion of fuel gases or fuel gas mixtures, it is known in the art to use stepped gas burners.
  • the fuel gas is discharged via the primary gas nozzles in a first combustion step in the combustion chamber or furnace chamber, mixed with oxygen or an oxygen-containing gas and burned.
  • secondary gas nozzles are arranged downstream of the primary gas nozzles, which inject a further portion of fuel gas into the combustion chamber or furnace chamber and completely oxidize the oxidizable components in the gas mixture flowing past there. burn.
  • a gas burner is, for example, off US 5 551 869 A known.
  • Such gas burners are, for example, industrially used in ceiling-fired synthesis gas furnaces for the production of H 2 and CO.
  • synthesis gas furnaces a multiplicity of reaction tubes filled with catalyst are passed through the furnace space fired from above.
  • the reaction tubes arranged in lanes are heated by a plurality of stepped gas burners which fire into the gap between the lanes.
  • the feed gas usually a lower hydrocarbon, such as methane, propane, butane or a mixture of these hydrocarbons. It is crucial that the reaction tubes are heated evenly. In regions of the catalyst-filled reaction tubes which are not heated to the required reaction temperature, no or reduced reaction takes place, whereby the total conversion of the synthesis process decreases. If local overheating occurs, there is a risk of material damage.
  • the object of the invention is thus to provide an improved method and a gas burner are available, in which the reaction tubes are thermally stressed evenly as possible.
  • a gas burner for combustion of fuel gases or fuel gas mixtures is disclosed together with oxygen or oxygen-containing gas mixtures comprising at least one primary gas nozzle and at least two secondary gas nozzles, which with a common central supply line are connected.
  • the secondary gas nozzles are arranged substantially radially and symmetrically about the primary gas nozzle. Upstream of the primary gas nozzle at least one element for flow guidance is arranged.
  • the Primärgasdüse has a plurality of radially arranged openings, wherein a part number of the openings are formed as horizontal openings whose axes perpendicular to the axis of rotation of the Primärgasdüse lead through the wall of the Primärgasdüse and the other part number are formed as non-horizontal openings whose axes in the direction provided Main flow direction are inclined towards the axis of rotation of the primary gas nozzle.
  • axis of an opening should always be understood to mean the perpendicular to the free cross-sectional area of this opening, regardless of whether it is a round or differently shaped cross-sectional area.
  • circular cross-sectional areas it should also be understood, with regard to the position of this axis in the cross-sectional area, that this axis passes through the center and, in the case of non-circular cross-sectional areas, that the axis passes through the geometric center of this cross-sectional area.
  • Essential to the gas burner according to the invention is that the axes of each non-horizontal openings are directed to a point of a centerline between each two secondary gas nozzles, and the centerline is defined as an imaginary line parallel to the axis of rotation of the primary gas nozzle and centered between two adjacent secondary gas nozzles.
  • the number of non-horizontal openings is identical to the number of secondary gas nozzles.
  • An improved embodiment is that the secondary gas nozzles are arranged downstream of the primary gas nozzle.
  • the gas burner can be optimized by the primary gas nozzle having one or more vertical openings, so that in the installed state, the fuel gas can flow in the direction of the axis of rotation.
  • the gas burner head or the nozzle of the primary gas nozzle is a wearing part, which must be changed regularly. Therefore, an optimized variant is that the primary gas burner, a releasable nozzle head is provided, in which the non-horizontal openings are introduced, and the nozzle head is shaped or constructive elements are provided thereon, the axis of each non-horizontal opening at a point of Centerline is directed between two secondary gas nozzles.
  • the nozzle could be fixed by means of a flange on the central tube and the position of the holes prevents misplacement of the openings.
  • the gas burner head could be applied via a screw on the central tube and carried out by means of a spring-mounted ball, a Kontersplint or a lock screw fixing the final position.
  • Other design variants are also conceivable.
  • the gas burner can be further improved, in which an upstream of the primary gas nozzle arranged element for flow guidance is applied directly to the nozzle head or connected thereto.
  • the invention further comprises a reforming furnace for producing hydrogen and carbon monoxide-containing synthesis gas, in which the gas burner according to one of the preceding embodiments is used. Also included in the invention is a process for the production of hydrogen and carbon monoxide-containing synthesis gas, in which a reforming furnace is provided with a gas burner according to one of the aforementioned embodiments.
  • Fig. 1 and Fig. 2 shows an example of the gas burner according to the invention.
  • the invention is not limited to the embodiment shown.
  • Fig. 1 shows a sketch of the gas burner according to the invention and the arrangement of primary and secondary gas nozzles in a perspective view.
  • oxygen or an oxygen-containing gas mixture is passed via the channel 2.
  • central fuel gas line 3 From the centrally located in the burner channel 1 central fuel gas line 3 branch off four smaller fuel gas lines 4, which lead to the Sekundärgasdüsen 5.
  • These fuel gas lines 4 are arranged substantially symmetrically and lead radially from the central fuel gas line 3 to the outside and extend in a downward arc parallel to the wall of the burner channel 1 along, down.
  • the secondary gas nozzles are arranged.
  • a flow deflection 9 is arranged, which is formed in the present example as a screen.
  • Fig. 1 the center line 10 shown between two downwardly directed fuel gas lines 4 as a dashed line.
  • the center line 10 runs parallel to the central fuel gas line 3.
  • the solder on the openings of the non-horizontal openings is directed precisely to this center line 10.
  • This relationship has been outlined only for a non-horizontal opening 8, but applies to all other non-horizontal openings 8 in an analogous manner.
  • the flow direction of the fuel gas from the non-horizontal opening 8 is sketched by the dashed arrow 11.
  • Fig. 2 shows the detail view of the Primärgasdüse in an enlargement and in section AA, in the region of the non-horizontal openings 8.
  • the gas burner jet which leaves the Primärgasdüse through the horizontal openings 7, perpendicular to the axis of rotation 12 of the central fuel gas line. 3 stands.
  • This gas burner jet is indicated by the dashed arrow 13.
  • dashed arrows 4 the direction of the gas burner gas that are passed through the non-horizontal openings 8 in the burner channel 1.
  • Fig. 3a shows the use of the gas burner according to the invention, as in connection with Fig. 1 and Fig. 2 has been described.
  • the distance from the primary gas nozzle in millimeters is plotted on the X-axis and the diagram areas represent areas with the same temperature.
  • the temperature field of the device according to the invention was surprisingly homogeneous or uniformly stepped, as in Fig. 3a can be seen. There are no overheating or areas with very bad combustion. This leads to an optimal heating of adjacent reaction tubes and to a more complete combustion.
