Definitions

  • the invention relates to an atmospheric gas burner according to the preamble of the main claim.
  • the invention is thus based on the object to the effect of improving an atmospheric gas burner of the type mentioned, are that the need optimum NOX reduction values and that the reduction should adapt also largely m matterssgeometrie regardless of the U, the NOX reduction ie virtually any boiler that is equipped with an atmospheric gas burner should be reproducible.
  • the pocket-like bodies are longitudinally assigned to the burner tube, which then correspond approximately to the length of the burner tube, but can also be arranged shorter in a row as sections, the bodies forming the reducing element are arranged with their bottoms equally spaced from the surface of the burner tube.
  • the pocket-like bodies are arranged at a distance from one another which corresponds to their width, i.e. the area above the burner tube which is actually spatially occupied by the bodies is only about half of the total area occupied by flames.
  • the burner openings in the burner tubes are arranged in groups which are equally spaced from one another, the pocket-like bodies are advantageously arranged above the opening-free regions of the burner tube.
  • the reducing element consists of a plurality of such individual bodies, these are expediently arranged together on at least one carrier which is furthermore arranged such that it can be adjusted in a variable distance with respect to the burner tube, which provides a further possibility for optimizing the NOX reduction, with which possibility the fact is taken into account that the gases used can have different compositions, which may require different distance settings of the reducing element to the burner tube.
  • such pocket-shaped bodies can also be arranged in the longitudinal direction, that is to say parallel to the longitudinal axis of the burner tube, with a corresponding length dimensioning, such bodies are then advantageously provided in their bottoms with air inflow openings in order to ensure the aforementioned chimney effect even with such relatively long bodies.
  • the atmospheric gas burner consists of at least one burner tube 2 with a plurality of gas outflow openings 1, the element which reduces the flame temperature and thus the NOx formation being arranged in the flame region above the burner tube 2.
  • FIGS. 1, 2 For the sake of simplicity, FIGS.
  • the reducing element is always formed from the same individual parts, which are basically perpendicular to one another at a distance from one another
  • lamellae 3 which delimit flame shafts 4 and which, as shown and oriented to the noema
  • the fins 3 are cut to follow the curvature of the burner tube 2.
  • two lamellae 3 are advantageously and preferably combined with side walls 7 to form a manhole pocket 8, these boxes 8 each above an opening group 6 (on the right in FIGS. 1, 2) or between two opening groups 6 (left in Fig. 1, 2) are arranged above the burner tube 2.
  • This training as a shaft box 8 has the advantage that the lamellae 3 experience stiffening and are therefore less subject to warping due to the action of heat.
  • the effort required to attach the fins 3 to the burner tube is considerably reduced in comparison to the attachment of individual fins 3.
  • side walls 3 serving as fastening and holding elements side walls 3 can optionally be perforated in the vicinity of the burner tube 2 and provided in the fastening area with elongated holes for which small stud bolts are dotted on the burner tube, so that the boxes 8 with respect to their lower edges 5 Burner tube 2 can be fixed at variable distances.
  • the boxes 8 themselves form the flame shafts 4, while when the boxes 8 are arranged between groups of openings (on the left in FIG. 1, 2) the flame shafts 4 are each delimited by two boxes 8 will. Regardless of whether the boxes 8 are now arranged directly above an opening group 6 or between two opening groups 6, the shafts 8 are arranged in correspondence of one another due to the arrangement of the boxes 8 between them. Even with group arrangement and training, As illustrated in FIGS. 1, 2, the fins 3 could of course also be oriented parallel to the longitudinal axis of the burner tube, ie in rows one behind the other and side by side, with relatively short fins being preferred because of the risk of warping.
  • the reducing element is formed from a plurality of pocket-like bodies 9 arranged laterally and upwards distributed over the gas outflow openings 1 of the burner tube 2, the bottoms 10 of which advantageously merge into the lamellae and are arranged transversely to the burner tube 2 the shape of the curve of the burner tube 2 are also adapted.
  • Such bodies 9 can easily be drawn from a suitable metallic material with appropriate molding tools in one operation. Since, taking into account the usual lengths of burner tubes 2, at least about ten such bodies 9 must be assigned to each burner tube, the whole is formed into a uniformly attachable element, with the aid of two side supports 13, as can be seen in FIGS. 6, 7.
  • the carriers 13 are attached to the burner tube 2 in a suitable manner and as indicated in FIG. 7, for example, so that the bodies 9 with their bottoms 10 are arranged at a certain distance above the tube 2.
  • This attachment is preferably and advantageously also adjustable, so that the entire structure can be adjusted with the optimum distance from the burner tube 2.
  • the bodies 9 are expediently arranged at the same distance from one another on the burner tube 2 or on the supports 13. Since the gas outflow openings 1 are generally provided on such burner tubes 2, as can also be seen in FIGS. 4, 5 and as mentioned above, in groups 6, the pocket-like bodies 9 are advantageously above the opening-free areas of the burner tube 2 arranged since the flames standing above the gas outflow openings 1 are least disturbed. The flames burn unobstructed into the spaces between two bodies 9, which in turn, since they are open at the side (see flow arrow "in FIG. 7), are open to the lateral inflow of secondary air, which thereby cools the fins 3, so that they constantly withdraw heat from the hot flame area, thereby counteracting NOx formation.
