Definitions

  • the present invention relates to an atomizer nozzle for atomizing liquid fuel with the supply of air.
  • the energy required for atomization is drawn exclusively or at least predominantly from the atomizing air.
  • the atomization takes place for the subsequent combustion of the fuel.
  • the aim is to atomize as finely as possible.
  • the atomizer nozzle is intended to form the head of the burner lance of a gas turbine burner in order to also design it for the combustion of liquid fuel.
  • it is intended to be used in a gas turbine burner with a plurality of burner lances arranged on an annular combustion chamber.
  • the known atomizer nozzles are all unsuitable for the intended use in a gas turbine burner, in particular with a plurality of burner lances arranged on an annular combustion chamber. This is especially true with regard to their spatial atomization characteristics. It is too centered.
  • An atomizer nozzle that can be used within the intended scope must have a considerably more diversified atomization characteristic in order to ensure the cross-ignition between adjacent burner lances of the same combustion chamber.
  • the flame must be maintained when the fuel supply is reduced to very lean fuel / air ratios.
  • the atomizer nozzle should also have the highest possible atomization quality.
  • the object of the present invention is to provide an atomizer nozzle for atomizing liquid fuel with air supply, which meets the aforementioned requirements.
  • the atomizer nozzle according to the present invention accordingly has, inter alia, an inner chamber and an outer chamber surrounding it in the form of a jacket, which are provided with a plurality of outlet openings which overlap each other. Only a part of the air flows into the inner chamber and, in addition to coarse atomization of the liquid fuel also flowing into the inner chamber, serves essentially to distribute it evenly over its outlet openings. The other part of the air flows around the inner chamber through the outer chamber and is mixed in concentrically with the coarsely atomized fuel emerging from the outlet openings of the inner chamber. This prevents liquid fuel fragments from coming into contact with the walls of the outlet opening of the outer chamber. This effect occurs with the so far known atomizer nozzles and leads to a serious deterioration in the atomizer quality.
  • the flame stability is directly influenced by the atomizer nozzle.
  • FIG. 1 an atomizer nozzle is shown in a sectional view with an inner chamber 1 and an outer chamber 2.
  • the outer chamber 2 surrounds the inner chamber 1 in a jacket shape. It has an approximately hemispherical shape.
  • the air channel is also connected to the outer chamber 2 via connecting openings 8.
  • the inlet opening 7 of the air duct 5 points into the inner chamber either an annular cross-section or is formed by several annularly distributed individual openings. The same applies to the connection openings 8.
  • the inner chamber 1 On its side opposite the inlet openings 6 and 7, the inner chamber 1 is provided with a plurality of outlet openings 9, 10.
  • outlet openings 9 and four outlet openings 10 are provided.
  • the outlet openings 9 form an angle (polar angle) in the range between 20 ° and 45 °, but preferably of 25 °, with the axis 4.
  • the outlet openings 10 form an angle with the axis 4 in the range between 45 ° and 70 °, but preferably of 65 °.
  • the outlet openings 9 and 10 are offset from one another with respect to a rotation about the axis 4 by an angle of 45 ° (azimuth angle).
  • the cross section of the inner chamber 1 tapers towards its outlet openings 9, 10.
  • the inner chamber In the direction from its inlet openings 6, 7 towards its outlet openings 9, 10, the inner chamber is initially cylindrical, then frustoconical.
  • the outlet openings 9, 10 emanate from the frustoconical part, with respect to the said direction or the axis 4, of the same cross-section and at a corresponding distance from this axis.
  • the outlet openings 9, 10 accordingly form an annular row of holes in the inner chamber 1.
  • the outlet openings 9, 10 of the inner chamber 1 open into the outer chamber 2.
  • the latter has a correspondingly large number of outlet openings 11, 12 which overlap with the outlet openings 9, 10 of the inner chamber.
  • the cross section of the outlet openings 11, 12 of the outer chamber 2 is larger than the cross section of the outlet openings of the inner chamber 1. It preferably corresponds to the sum of the cross section of the outlet openings 9, 10 of the inner chamber 1 and the annular cross section of the openings of the outer chamber 2 towards their outlet openings.
  • the latter annular cross section results in ⁇ .DW, where D den Diameters of the outlet openings 11, 12 of the outer chamber 2 and W mean their width at their outlet openings 9, 10.
  • the outlet openings 11, 12 of the outer chamber 2 expand conically outwards.
  • a liquid fuel for example oil
  • the fuel flows into the inner chamber 1 through the inlet opening 6.
  • the diameter of the inlet opening 6 is approximately 10 times smaller than the diameter of the fuel channel 3 and is selected in the range between 0.6 mm and approximately 1.2 mm. Much smaller diameters than 0.6 mm are disadvantageous due to the risk of clogging of the inlet opening.
  • the diameter mentioned, the slight overpressure of the fuel in the fuel channel 3 and the length of the inner chamber 1 from its inlet opening 6 to its opposite wall are coordinated with one another in such a way that a thin fuel jet, approximately hitting the center of the opposite wall, results.
  • the length of the inner chamber 1 should therefore not be greater than approximately 20 times the diameter of its inlet opening 6.
  • Atomizing air is supplied via the air duct 5 and also under excess pressure. This overpressure is approximately 1.05 to 1.3 times, preferably 1.2 times the external pressure in the vicinity of the atomizing nozzle. The atomizing air must supply most of the energy required to atomize the liquid fuel.
  • a particularly good atomization cannot be achieved by being expelled from the outlet openings 9, 10 of the inner chamber 1 alone, since part of the fuel wets the walls of the outlet openings 9, 10 and forms a wall film.
  • the desired high atomization quality is only achieved by the outer chamber 2.
  • the main part of the atomizing air supplied through the air duct 5 enters the outer chamber 2 via the connecting openings 8 and flows around the inner chamber 1 2 atomizing air flowing concentrically around the fuel aerosol emerging from the outlet openings 9, 10 of the inner chamber 1. This is illustrated in Fig. 2. This effect reliably prevents the fuel drops of the fuel aerosol emerging from the inner chamber 1 from coming into contact with the walls of the outlet openings 11, 12. This leads to a considerable improvement in the atomizing quality.
  • the main part of the atomizing air preferably approx. 70-80%, flows through the outer chamber 2, its flow resistance and the flow resistance of the connection openings 8 must be dimensioned in a suitable manner in relation to the flow resistance through the inner chamber 1.
  • the diameter of the outlet openings 9, 10 of the inner chamber 1 should be A total of eight outlet openings are approximately a factor 1.33 larger than the diameter of their inlet opening 6.
  • grooves 13, which are indicated by dashed lines in FIG. 1, are preferably provided between the outlet openings 9, 10 and 11, 12 in the wall separating the inner chamber 1 from the outer chamber 2 on its side facing the latter.
  • the selected angles of the outlet openings 9, 10 and 11, 12 relative to the axis 4, in particular by dividing the outlet openings 9, 10 and 11, 12 into two groups 9, 11 and 10, 12 with different angles make one in view achieved optimal spatial atomization characteristics for the intended use in a gas turbine combustion chamber.
  • a reliable cross-ignition to neighboring burners of the same type is guaranteed by the outlet openings 10, 12.
  • the selected number of only a total of eight outlet openings 9, 10 or 11, 12 is advantageous to the extent that, given this number, no negative pressure zone constricting its width can form in the center of the flow field. There is enough space between the outlet openings for pressure equalization.
