Definitions

  • An object of the invention is to provide a fuel burner that reduces CO and Nox emissions.
  • Another object of the invention is to subject fuel/air premix to a naturally aspirated pattern of turbulent air having a curvilinear retrogradation and areas of helicoidal vortex currents of air to eliminate CO while further reducing NOx emissions .

  • Figure 2 shows a front view of a combustion cylinder according to a second embodiment
  • Figure 3 shows a front view of a combustion cylinder according to a third embodiment
  • Figure 4 shows a top view of the combustion cylinder of Figure 3 ;
  • Figure 5 shows a front view of a combustion cylinder according to a fourth embodiment

  • Figure 7 shows a front view of a combustion cylinder according to a fifth embodiment

  • Figures 15 and 16 illustrate a modification of the multiple burner head embodiment with the addition of external vortex fins
  • Figures 19 and 20 illustrate a front and top view, respectively, of a ninth embodiment .
  • the air mixer body 6 has a proximal end and a distal end.
  • the air mixer body 6 has three primary air inlet holes 8 at the proximal end.
  • One of ordinary skill in the art would recognize that the number and size of such holes may be varied in relation to the size of the orifice 7.
  • the distal end of the air mixer body 6, farthest from the first extremity terminates in a hemispherical nozzle cap 9.
  • the cap 9 has seven nozzle cap slots 10. The number and area of the slots may be varied by one skilled in the art in relation to the size of the orifice 7 and the primary air inlet holes 8.
  • the second embodiment shown in Figure 2 illustrates a moveable assemble bracket 11 that is attached to the exterior of the combustion cylinder 1 and the fuel inlet pipe 5.
  • the manner of attachment and movement may vary without limiting the scope of the invention.
  • the bracket 11 is adjustable to enable the air mixer body 6 to be positioned closer to the second extremity 3 of the combustion cylinder 1. When the air mixer body 6 is closer to the second extremity 3 , the pressure at the primary air inlet holes 8 increases, so that the resultant combustion reduces CO and NOx emissions even further than in the embodiment of Figure 1.
  • the fourth embodiment as illustrated in Figure 5 and Figure 6 shows a turbulence disk 14 attached to the exterior of the air mixer body 6.
  • Figure 6, similarly to Figure 4 is a view of the embodiment from the second extremity 3 through the combustion cylinder 1 toward the first extremity 2.
  • two different zones of air pressure in the regulated turbulent secondary combustion air develop after primary ignition.
  • One zone is above and one below the turbulence disk 14.
  • the sixth embodiment as illustrated in Figures 9 and 10 shows a confined cylindrical air guide aperture 16, with Figure 10 being the same view as Figure 8 in the fifth embodiment.
  • Several vortex fins 17 project into the air guide aperture 16 closer to the second extremity 3.
  • Vortex slots 18 fill the interstices between the vortex fins 17.
  • the force of the naturally aspirated rising air through the vortex slots creates an area of helicoidal vortex air currents in the secondary combustion air.
  • the low-flow velocities of vortex air currents in this area further entrain the fuel -air premix and improve combustion. As a consequence, CO emissions remain practically eliminated (as in the prior embodiment) , yet NOx emissions are further reduced.
  • Figures 11 and 12 completely illustrate the sixth embodiment of Figure 9 with the view of Figure 11 rotated 90 degrees on the vertical axis. These views are included to more clearly show that air guide 15 is hollow and includes an opening closer to the first extremity 2.
  • NOx reduction is achieved without use of devices such as laterally injected combustion air forming a secondary torroidal recirculation zone in the combustion cylinder 1 further downstream of the primary combustion area.
  • CO emissions are practically eliminated.

Abstract

L'invention concerne un brûleur de carburant comprenant un cylindre à combustion tubulaire ouvert au niveau de première et seconde extrémités opposées. Un tuyau d'entrée de carburant comporte une première extrémité s'étendant à travers la première extrémité du cylindre de combustion partialement dans le cylindre de combustion et une seconde extrémité s'étendant vers l'extérieur du cylindre de combustion. Le brûleur de carburant comprend également une tête de brûleur reliée à la première extrémité du tuyau d'entrée de carburant et un orifice relié entre la tête du brûleur et la première extrémité du tuyau d'entrée de carburant. La tête du brûleur est structurée et disposée de manière que le carburant brûlé déchargé au niveau de la seconde extrémité du cylindre de combustion produise des émissions en CO et NOx réduites.
