Definitions

  • the invention relates to a device for burning combustible materials with a fuel nozzle and at least one air supply duct for the separate supply of combustion air.
  • the invention has for its object to provide a device for burning combustible substances, in particular for the disposal of chemical substances by combustion, in which the fuel is fed to a fuel nozzle and the combustion air separately via at least one air supply channel and which is also with difficult and changing boundary conditions a complete burn should ensure.
  • the solution to this problem by the invention is characterized in that at least one vortex installation surface producing a leading edge vortex system in the combustion air and / or in the fuel jet is arranged in the outlet region of the fuel nozzle and the air supply duct.
  • the arrangement of at least one vortex installation surface according to the invention results in a leading edge vortex system which, through a targeted, intensive and early merging of fuel and combustion air, produces complete combustion within the flame core which forms, so that incomplete combustion with the result of fuel residues in the flue gas among all Circumstances is avoided.
  • the vortex installation surface can either be arranged in the flow cross section of the combustion air or the fuel; it can be arranged within the channel cross-section for the combustion air or for the fuel or in the flow direction of combustion air or fuel behind the channel. If the arrangement of the vortex installation surface takes place behind the actual duct, a position or formation of the vortex installation surface in the flow cross section of both the combustion air and the fuel can be selected.
  • the vortex installation surface for producing the leading edge vortex system can be designed with straight or curved leading edges, for example in the form of a delta or rhombus or a circular or oval disc. Furthermore, it is possible according to the invention to arrange a plurality of such vortex installation surfaces distributed over the circular or annular flow cross section of the fuel and / or the combustion air.
  • the vortex installation surface creates a stationary, three-dimensional leading edge vortex system, which ensures a very quick and intensive mixture of fuel and combustion air and is therefore the cause of a complete combustion of the fuel.
  • the respective design and arrangement of the vortex installation surface or vortex installation surfaces can be tailored to the individual case.
  • FIGS. 1 to 4 each schematically show a fuel nozzle 1 which, in all exemplary embodiments, is arranged centrally in an air supply duct 2.
  • the combustible material emerging from the fuel nozzle 1 is to be burned while supplying the combustion air emerging from the air supply duct 2, it also being conceivable that primary air has already been added to the combustible substance supplied to the fuel nozzle 1.
  • a delta-shaped vortex installation surface 3 is arranged in the first exemplary embodiment according to FIG. 1, which is oriented obliquely to the flow direction of the fuel and the combustion air and has such large dimensions that, according to the end view in FIG lies in the flow cross-section of the fuel as well as the combustion air.
  • a total of four triangular vortex installation surfaces 4 are arranged behind the annular mouth of the air supply duct 2. These vortex installation surfaces 4, which are evenly distributed over the circumference of the air supply duct 2, also produce leading edge vortex systems, as shown in the right part of FIG Complete combustion is also achieved in this case.
  • the third exemplary embodiment according to FIG. 3 shows an arrangement of a likewise triangular swirl installation surface 5 which deviates from the above described exemplary embodiments.
  • This also results in an intensive mixing of fuel and combustion air due to a stationary leading edge vortex system, which is primarily generated in the flow of fuel, but causes an intensive admixture of the combustion air surrounding the fuel by the stationary vortex, so that even in this embodiment within a very short mixing distance such a sufficient admixture of combustion air to the fuel that there is a complete combustion of the combustible material.
  • swirl installation surfaces 6 and 7 are arranged both within the mouth of the fuel nozzle 1 and the air supply duct 2.
  • a total of six triangular swirl installation surfaces 7 are arranged uniformly distributed in the annular mouth region of the air supply duct 2.
  • leading edge vortex systems with stationary vortices are generated both in the fuel emerging from the fuel nozzle 1 and in the combustion air emerging from the air supply duct 2, which altogether bring about a complete mixing of fuel and combustion air by their meeting within a very short mixing distance, so that this too Embodiment a complete combustion of the combustible material is achieved.
  • 5 to 8 show preferred embodiments of the vortex installation surfaces.
  • 5 shows a delta-shaped or triangular vortex installation surface 3 already shown in FIGS. 1 to 4, whereas the vortex installation surface 8 is designed as a rhombus.
  • the vortex installation surface 6 according to FIG. 7 is - as already drawn in FIG. 4 - oval;
  • Fig. 8 shows a circular vortex installation surface 9. All these embodiments have in common that when they are set at an acute angle to the direction of flow, they generate a vortex system with their first flowed leading edges, which consists of stationary vortexes and thus a very short mixing distance intensive but low-loss mixing results.
