  • the invention relates to a swirl atomizing nozzle for the atomization of liquid fuel, a method for producing the swirl atomizing nozzle and a nozzle assembly for a combustion chamber, in particular for a gas turbine, with the swirl atomizing nozzle.
  • a gas turbine has a compressor, a combustion chamber and a turbine.
  • a combustion air-fuel mixture is brought to the ignition, whereby a Schugastrom arises.
  • the heating gas stream is expanded in the turbine, which drives the compressor and provides a net output.
  • the net power may be, for example, a shaft power for driving a generator in a power plant.
  • both gaseous fuels and liquid fuels can be burned in the combustion chamber. If a liquid fuel is used, it must be atomised to a pre-determined droplet size distribution and concentration in the combustion air before combustion. Conventionally, the atomization of liquid fuel is accomplished with a spray nozzle.
  • the atomizing nozzle is housed directly in the combustion chamber or in a premixing chamber. Due to the cramped conditions in the combustion chamber or the premixing chamber, it is necessary that the atomizing nozzle should only have a predetermined limited depth.
  • An atomizing nozzle constructed taking into account the limited structural depth has a limited atomizing effect, so that the atomizing nozzle with an additional swirl generating device is equipped to generate a twist in the liquid fuel-combustion air mixture.

Further, the liquid fuel-air mixture flows from the nozzle chamber through the swirl atomizing nozzle into the gas turbine combustor, and the swirl atomizing nozzle is accommodated in the cone portion of the nozzle body. As a result, the atomization of the liquid fuel caused by swirling takes place in the combustion air the cone section of the nozzle block by means of the swirl atomizing nozzle, whereby a high homogeneity of the droplet size distribution of the liquid fuel in the combustion air can be achieved. Thus, the atomization of the liquid fuel in the combustion air with the nozzle is effective.
  • the diameter-to-height ratio of the nozzle body is less than one.
  • the height of the nozzle body is small, so that the swirl atomizing nozzle has a low overall height. This is advantageous since only limited space is available in the nozzle chamber chamber outlet hole, so that the swirl atomizing nozzle according to the invention can be installed in the nozzle assembly according to the invention.
  • the swirl atomizing nozzle in a plane has two point-symmetrically arranged around the center of the hollow cylinder inlet holes, in particular holes and / or slots, having their longitudinal axes parallel to each other.
  • the plane is located closer to the ground than to the head.

  • the blank can be supported on the holding sleeve in the manufacture of the swirl atomizing nozzle.
  • the bottom and the area of the blank between the annular step and the bottom are held by the holding sleeve, so that this area of the forming is not affected. Rather, the area of the blank is affected from the annular step to the open longitudinal end of the blank, so that an undesired bending of the blank in the region of the blank between the annular step and the ground in the preparation of the swirl atomizing nozzle can not occur.
