Definitions

  • the invention relates to a method for the evaporation and combustion of liquid fuels, in which air, gas or water vapor is admixed to the atomized fuel, and to a burner for liquid fuels, which has an outlet opening provided with a conically tapering jacket tube at its front end, before the latter Outlet opening is an atomizer nozzle is arranged, in the outer circumferential grooves are provided, one ends of which emanate from an annular space formed by the atomizer nozzle and the jacket tube, which is connected to a compressed gas supply and the other ends of which open into the outlet space of the atomizer nozzle.
  • DE-OS 26 56 439 is a method of atomization and combustion of liquid fuel and a burner operating according to this method are known, in which high-tension air is brought together in a jet in front of the oil outlet nozzle with vortex formation, thereby sucking and atomizing the liquid fuel and preparing this premix by introducing secondary air so that it is burned practically without soot can.
  • the disadvantage of the burners according to the prior art is that the fuel atomization is brought about by the exchange of kinetic energy between the liquid fuel stream and the high-tension air broken down into partial jets. This known way of working requires a large mass flow of highly compressed air.
  • the invention has for its object to provide a method and a burner of the type mentioned, which are not only easy to implement while avoiding the aforementioned disadvantages, but also a completely soot-free combustion with a very hot, stoichiometric, non-luminous flame.
  • this object is achieved in that the that the fuel is sprayed under high pressure in an atomizing nozzle and the droplets formed thereby with air or other gas jets with a static pressure which is lower than the vapor pressure of the liquid to be atomized and at a speed which is greater than the speed of sound, be further divided and evaporated.
  • the fuel is sprayed, for example, at a pressure of between 5 and 20 bar in the atomizer nozzle, the air or other gas jets having a pressure, for example initially 2.5 bar, which is reduced compared to this pressure and which is converted into a speed of, for example, 1-2 Mach .
  • the fuel vapor-gas premix is mixed with secondary air at low admission pressure and completely burned in a burner tube.
  • the inventive method finely atomizes the liquid fuel by means of air or gas jets of comparatively low mass, which have speeds greater than the speed of sound.
  • the atomizing air or the atomizing gas are introduced into the stream of the pre-atomized fuel via nozzles which have the characteristics of Laval nozzles, in which the inflowing compressed gas is passed through a space with a continuously narrowing cross section and after flowing through the narrowest cross section into one ever expanding space arrives and flows out of this to the mouth of the atomizing nozzle, the compression pressure still inherent in the jet being converted by expansion into a speed greater than 1 Mach.
  • the gas jets escaping at supersonic speed cause strong compression surges, which are periodically replaced by strong vacuum pulses.
  • the process of evaporation and combustion of liquid fuels according to the invention enables the combustion of liquid fuels from low to very high viscosity, so that in particular even heavy fuel oil can be burned without soot after preheating to approx. 90 ° C with the same flame quality.
  • the object underlying the invention is achieved in that the atomizer nozzle with its outer
  • the surface on the inner surface of the conically tapering front end of the casing tube lies in a line shape, forming a space that tapers from the area in front of one end of the grooves to its narrowest cross section and one that narrows from the narrowest cross section of the grooves to the area behind the other ends of the groove widening space.
  • the geometry of the arrangement in the area of the pressure line of the atomizer nozzle against the conically tapering front end of the casing tube is a Laval nozzle cut along the central plane and thus halved.
  • the atomizer nozzle advantageously has a spherical outer peripheral surface at its front end.
  • the atomizer nozzle is provided at its front end with a circumferential surface which corresponds to the lateral surfaces of two truncated cones, the front of which have a vertex angle larger and the rear have a vertex angle smaller than the cone angle of the cladding tube.
  • the grooves run parallel to the inner circumferential surface of the conically tapering front end of the casing tube.
  • the longitudinal axes of the grooves can run at an angle to the longitudinal axis of the casing tube and the atomizing nozzle, so that the compressed gas flowing out at supersonic speed into a Vortex movement is offset about the central axis, which leads to a dynamic mixing of the oil-primary gas mixture.
  • the grooves can also be arranged in the inner circumferential surface of the conically tapering front end of the casing tube instead of in the outer circumferential surface of the atomizing nozzle, the geometry otherwise remaining unchanged.
  • the cross section of the outlet opening is advantageously larger than the sum of the cross sections of the grooves at their narrowest point.
  • the grooves it is also possible to provide only one groove.
  • the groove or the grooves can be replaced by one notch slot or several notch slots, which is a significant advantage in terms of production technology.
