Definitions

  • the invention relates to a device for the combustion of fuels in a combustion chamber by means of burners which are arranged in several planes lying parallel to one another tangentially to the combustion chamber axis, a pair of secondary air nozzles being assigned to each burner comprising at least one fuel nozzle and nozzles for supply in the flue gas direction behind the last burner level of additional air are arranged.
  • Such devices for burning fossil fuels and industrial residues in gaseous, liquid or solid form are known.
  • the fuel nozzles are arranged in the corners of a combustion chamber which is rectangular in cross section and are oriented tangentially to a combustion circuit which results in the center of the combustion chamber.
  • Each fuel nozzle is assigned two secondary air nozzles, which are also arranged in the corner of the combustion chamber above and below the fuel nozzle.
  • Fuel and secondary air nozzles can be in several levels, i.e. be arranged one behind the other or one above the other in the longitudinal direction of the combustion chamber.
  • nozzles for supplying additional air are arranged in order to achieve low nitrogen oxide emissions.
  • the invention has for its object the known device for the combustion of fossil fuels and Develop industrial residues in gaseous, liquid or solid form such that these fuels can be burned with low nitrogen oxide emissions without the risk of corrosion of the combustion chamber walls.
  • the solution to this problem by the invention is characterized in that the fuel and secondary air nozzles in the surface of the combustion chamber walls are arranged laterally offset to the longitudinal axis of the combustion chamber, that the secondary air nozzles are arranged laterally next to the fuel nozzles in each burner level, that at least one additional air nozzle is assigned to each fuel nozzle , which lies behind the respective fuel nozzle in the direction of the flue gas, and that each fuel nozzle is additionally assigned at least one further secondary air nozzle which is arranged in the region between the combustion chamber wall which is closest to the wall and the secondary air nozzle which is close to the wall.
  • the advantage is achieved that even with extremely substoichiometric operation in the primary flame zone in order to achieve low-nitrogen oxide combustion, which is made possible by the large number of additional nozzles located in all burner levels, the secondary air nozzles arranged laterally to the fuel nozzles prevent the Combustion chamber walls are exposed to a corrosion attack resulting from low-nitrogen oxide combustion, because the secondary air forms a veil that separates the combustion chamber walls from the dangerous smoke gases.
  • the exemplary embodiment shown in the drawing shows a vertical combustion chamber which is formed by four flat combustion chamber walls 1 and - as can be seen from FIG. 2 - has a square combustion chamber cross section.
  • the vertical combustion chamber longitudinal axis 2 is shown in Fig.1. With respect to this combustion chamber longitudinal axis 2, a plurality of burner levels are formed one above the other, two of which can be seen in FIG.
  • each burner level In the exemplary embodiment, four fuel nozzles 3 are arranged in each burner level.
  • the plan view in FIG. 2 shows that these fuel nozzles 3 are oriented in such a way that they run tangentially to a combustion circuit 4 indicated by dash-dotted lines in FIG. Three of the total of four fuel nozzles 3 are only indicated by arrows in FIG.
  • each fuel nozzle 3 To the side of each fuel nozzle 3, two secondary air nozzles 5 are arranged at the same distance, which together with the primary air introduced through the fuel nozzle 3 provide the combustion air necessary for substoichiometric combustion.
  • An additional air nozzle 6 is also arranged behind each fuel nozzle 3 in the flue gas direction, through which tertiary air is supplied.
  • each fuel nozzle 3 is additionally assigned at least one further secondary air nozzle 7, which is arranged in the area between the closest combustion chamber wall 1 and the secondary air nozzle 5 close to the wall.
  • the air emerging from the additional secondary air nozzle 7 forms an air curtain which separates the combustion chamber wall 1 from the dangerous flue gases, so that the combustion chamber walls 1 are not exposed to any corrosion attack even during extremely substoichiometric operation in the primary flame zone.
  • the secondary air nozzles 5 and the additional air nozzles 6 enable a staged air supply and thus a low-carbon x for the NO combustion necessary substoichiometric operating mode in the primary zone of the flame.
  • the nozzles 5 and 6 have the function of stepped air nozzles.
