Definitions

  • Rotating combustion chamber with water injection and cooling for a turbine Rotating combustion chamber with water injection and cooling for a turbine.
  • the invention relates to a method for producing a mixture of fuel gases and steam for operating a turbine and a machine for the continuous production of the fuel gas / steam mixture which rotates the entire machine by means of a turbine fixed to the combustion chamber and thus serves as an engine.
  • the main problem with the known gas turbines is that too much work is required for the compressor, since a high excess of air is necessary for the gas turbine process in order to reduce the temperature of the fuel gases, so that in particular the material of the turbine blades is not overheated.
  • This problem of the excessively high combustion gas temperature can only be solved to a limited extent by using heat-resistant material, as a result of which the efficiency of the gas turbine can be improved because of the lower excess air number that can be achieved.
  • the evaporation of the water from the water ring takes place without any problems, since the hotter water, which has a lower density, moves inwards to the free surface of the water ring, from where the steam reaches the open combustion chamber for mixing with the fuel gases.
  • the water, which has a lower temperature is centrifuged against the inner wall of the housing shell (15) and thereby pressurized, which causes an increase in the water boiling temperature. This process involves an open cooling process thanks to the very high cooling capacity of the water, water consumption remains within limits.
  • FIG. 1 A machine which can be used to carry out the method described in claim 1 is shown in FIG.
  • the fuel gas / steam mixture passes centrifugally through the guide vanes into the radial turbine (3) and rotates the turbine together with the combustion chamber.
  • the guide vane device (5) can be made axially displaceable, so that a bypass is created. This bypass is particularly important if the fuel gas / steam mixture is passed into another turbine after leaving the turbine, or is used as a thrust or as a process medium. With this bypass it is possible to drive optimally even in partial load operation.
  • An increase in the pressure of the compressed air is achieved if the radial compressor is preceded by a single or multi-stage axial compressor which also rotates in the hollow shaft with the housing.
  • the claim 7 relates to the compressor side, whereby to increase the pressure in the combustion chamber not an increased amount of work is required by the compressor, but rather by injecting water through the central and fixed line (13) and subsequent centrifugal ejection into the combustion chamber after passing the orifices (9) help to atomize the water.
  • the resulting droplet wall acts like a liquid wall, which means that a higher pressure in the combustion chamber can be counteracted. If more water gets into the housing shell than is evaporated, the excess water is inevitably returned by means of the feed / collecting pipe (6).

Abstract

Un procédé permet d'obtenir un mélange de gaz de combustion et de vapeur dans une chambre de combustion rotative formée d'une enveloppe dont la circonférence extérieure est entourée d'un anneau d'eau. Le front des flammes et les gaz de combustion émanant du brûleur annulaire central touchent l'anneau d'eau de refroidissement sur toute sa circonférence. La vapeur qui en résulte se mélange aux gaz de combustion et entraîne une réduction de la température avant que le mélange ne parvienne à la turbine assujettie à l'enveloppe et qui provoque la rotation. On utilise au lieu de l'excédent d'air surtout de l'eau pour assurer le refroidissement, ce qui permet d'obtenir un rendement élevé. Une machine de mise en ÷uvre du procédé comprend une enveloppe (15) qui sert de chambre de combustion (2) assujettie à un compresseur (1) et à une turbine (3). L'air pénètre dans le compresseur (1) à travers l'arbre creux et aspire la vapeur contenue dans la pré-chambre (11, 12). Du combustible y est ajouté (8, 9). La flamme touche l'anneau d'eau de la chambre de combustion, qui sert d'organe de refroidissement et de génération de vapeur. Cette machine sert de moteur, le mélange de gaz de combustion et de vapeur pouvant être utilisé ultérieurement comme porteur d'énergie.
