Definitions

  • the invention relates to a surface gas burner with a number of plates arranged essentially parallel and with gap-shaped spaces, the edges of which form a burner surface on one side and adjoin a fuel gas mixing space on the opposite side, with which the gap-shaped spaces are in open connection stand.
  • Conventional gas burners of this type consist of many flat or corrugated sheets arranged side by side. This creates a block-shaped structure that forms a grid-shaped burner surface on one side and adjoins a fuel gas mixing chamber on the other side. With this arrangement, the sheets must be housed in a frame.
  • the purpose of the invention is to create a gas burner of the type described above, which can be manufactured more simply and inexpensively, and which fully meets or even exceeds the requirements in terms of environmental pollution, in particular with regard to the nitrogen oxides in the exhaust gas.
  • the sheets are connected as ribs to a tube directed essentially transversely to the planes of the sheets.
  • the surface gas burner has at least two tubes arranged next to one another, provided with fins, and the tube axes and the fins of adjacent tubes each lie essentially in one plane. Parts of the fins can be bent in such a way that lateral connection surfaces to adjacent tubes provided with fins are formed.
  • a surface burner can be realized in a simple manner with a finned tube, as is usually used in heat exchangers. This not only enables a simple production of a surface burner, but also offers the advantages of a cooled burner with a high dm 2 load, a low burning height and a low nitrogen oxide emission.
  • a surface burner is suitable for the usual arrangement, ie with flames pointing upwards, but also for the arrangement with flames pointing downwards.
  • the gas burner may have a plurality of tubes provided with fins, the tube axes being substantially in the same plane and the fins of two adjacent tubes also being substantially in one plane.
  • the fins of adjacent pipes can rest against each other. If two or more levels of tubes are arranged one above the other, the tube axes of one level can be offset with respect to the tube axes of the other level.
  • a good lateral connection of adjacent ribs is given if the ribs have a rectangular shape.
  • conventional finned tubes often have a round outline or a shape that deviates from the rectangular shape.
  • the bent parts of the ribs should mainly be on the burner surface or on the surface facing the fuel mixing room. Of course, it is also possible to cut off rib parts or remove them in some other way instead of bending them over. Depending on the distance between the ribs, bending parts of the ribs can also result in the advantage that the gas-air mixture is additionally whirled up, which has a favorable effect on the mixing of gas and air.
  • the invention provided that these sheet metal edges are covered by a plate-shaped part which extends parallel in the direction of the tube. At least the longitudinal edge of the plate-shaped part should lie to or in the burner surface or to or in the surface adjacent to the fuel mixing space. If the plate-shaped part is on the side of the surface burner, it should be attached so that it mainly touches the sheet metal edges to be covered. This creates an additional swirl effect on the gas-air mixture. If the plate-shaped part is located on the side of the gas-air mixing space, it should be attached in such a way that it lies predominantly on the surface adjacent to the fuel mixing space. In this way, the management of the gas-air mixture is promoted.
  • the burner arrangement shown in Fig. 1 contains a tube 1 which is provided with fins 2.
  • the outline of each rib 2 forms a square, so that a block of sheet metal can be built exactly at a distance.
  • the sheets are closed off by frame parts on two opposite sides. This forms a grid-shaped inflow surface for a gas-air mixture on the one hand and a burner surface on the other.
  • a longer finned tube piece can be used and / or some finned tube pieces can be placed side by side in such a way that both the tube axes of the tube parts and the adjacent fins lie in one plane.
  • the outline of the ribs can also have a shape other than a square, e.g. the shape of a rectangle or a regular hexagon. This last embodiment is shown in Figures 3-5. Here pipes 3 and 5 with hexagonal ribs 4 and 6 are arranged in two levels.
  • the ribs 4 each have a bent part 4a in the form of an isosceles triangle, the two equal legs of which are two longitudinal edges of a regular hexagon. 5, the successive bent parts 4a of the ribs 4 partially overlap on a tube 3. These parts 4a, as shown in FIG. 4, are bent to less than 90 °.
  • the mutually parallel longitudinal edges of the regular hexagon adjoining the bent parts 4a adjoin similar finned tubes which are located in the same plane.
  • the two other outline edges of the hexagons are connected to the edges of a row of tubes 5 with fins 6, which lie on a lower level and are arranged offset such that a substantially flat surface is formed by the various abutting fins 4 and 6.
  • the ribs 6 also have bent parts 6a which have the same shape as the bent parts 4a; the bent parts 6a form an essentially flat lower surface which can adjoin the (not shown) fuel gas mixing space.
  • the tubes 3 with the fins 4 and 4a are similar to the tubes 5 with the fins 6 and 6a, so that the burner can be made with a single type of finned tube.
  • the burner surface was assumed to be on the upper side and the gas-air supply surface on the lower side, the burner can also be used in the reverse order.
  • FIGS. 6 and 7 A third exemplary embodiment is shown in FIGS. 6 and 7.
  • Tubes 7 with ribs 8 with a circular outline are used here in a particularly advantageous manner.
  • each fin 8 has four uniformly bent parts 8a distributed symmetrically over the outline.
  • the surface of the bent part is selected in relation to the distance between two ribs so that the bent part fits exactly between two ribs. In this way, a bending angle of 90 ° is possible.
  • the profile 9 contains a central part 9a, which adjoins a laterally bent part 8a, a guide part 9b mounted perpendicular to the central part 9a and a swivel part 9c arranged at an angle to the central part 9a.
  • the guide part 9b is located on the side of the gas-air mixing space and promotes the uniform supply of the gas-air mixture to the burner.
  • the swirl part 9c is located on the burner surface and, by means of an additional swirl movement, ensures a better mixture of gas and air and thereby optimal combustion.
  • Fig. 6 flames are shown on the top of the burner. Again, the burner can also be placed upside down so that the flames are directed downwards.
  • a liquid preferably water
  • Such a burner can also be light and inexpensive be made by placing one or more tubes in a frame.
  • the sheets, which form the guide channels for the gas-air mixture, are uniformly connected to the pipes and enclose the predetermined distance without requiring complicated or time-consuming work.
  • rib parts can not only be bent, but also cut off or removed in some other way.
  • the tubes if they are offset from one another by more than one fin thickness, can be pushed further together, the bent fin parts forming further guide and swirl plates.
  • two loose strips corresponding to parts 9b and 9c can also be used. As a result, the middle parts 9a are unnecessary.
