Definitions

  • the invention relates to a burner according to the preamble of patent claim 1.
  • a burner of the type mentioned is according to the EP 1 538 395 A1 (look there FIG. 1 ) known.
  • This gas blower burner consists of a cylindrical burner body (flame body) having at one of its two end faces a supply for a fuel-air mixture to be combusted (typically natural gas-air mixture), which is closed at its other end face and its peripheral surface at least partially Burning surface is formed, wherein in the burner body, a sleeve-shaped flow guide element for the fuel-air mixture is arranged, which adjoins the feed, which extends into the region of the closed end side and which defines a sleeve inner and a sleeve outer space, which together in the Area of the closed end side are pneumatically in communication, wherein the sleeve outer space is formed ringpaltartig and extends at least between the focal surface and the flow guide element.
  • the invention has for its object to improve the combustion or the burning behavior of a burner of the type mentioned.
  • the annular gap-like sleeve outer space is designed to be smaller in the direction of the feed, at least in the region of the burning surface, with respect to its flow cross-sectional area.
  • the supply of the fuel-air mixture to the fuel surface is more uniform, namely by the fact that the space between the flow guide element and the fuel surface in the direction of gas supply is getting smaller, which takes into account the knowledge, that already progressively more mixture has passed through the focal surface with advancing run length in the direction of supply, thus flowing an increasingly smaller volume flow in the direction of supply.
  • the in the FIGS. 1 to 3 shown gas blower burner consists of a cylindrical burner body 1, which has at one of its two end faces 2, a supply 3 for a gas-air mixture to be burned.
  • the burner body 1 is also closed at its other end face 4.
  • Its cylindrical peripheral surface (lateral surface, also called distribution surface) is at least partially formed as a focal surface 5, wherein the lateral surface in the region of the focal surface 5 has through holes for the gas-air mixture and enclosed by the actual focal surface 5 forming metallic wires (wire mesh or wire mesh) is.
  • the outer burner body 1 from a first, the supply 3 forming hollow cylindrical pipe section 11, from a second, enclosed by the combustion surface 5, hollow cylindrical pipe section 12 with passage openings for the fuel-air mixture and a lid-like end face. 4 is formed.
  • the closed end face 4 of the burner body 1 is in this case with a convex curvature pointing in the direction of the flow guide element 6 13, which contributes in cooperation with the yet to be explained flow guide element 6 to a uniform distribution of the fuel-air mixture in the interior of the burner body 1.
  • the flow of the fuel-air mixture advantageously cools the curved front side 4.
  • a sleeve-shaped flow guide element 6 for the gas-air mixture adjoins the feed 3 and extends into the region of the closed end face 4. It defines a sleeve inner and a sleeve outer space 8, which spaces with each other in the region of the closed end 4 via corresponding openings or the like (for example to be explained recesses 10) are pneumatically in communication.
  • the sleeve outer space 8 is formed ring-like and extends at least between the focal surface 5 and the flow guide element 6. As in particular from FIG. 2 can be seen, the sleeve outer space 8 extends in the preferred embodiment, even from one to the other end face 3, 4th
  • the ring-gap-like sleeve outer space 8 is formed at least in the region of the focal surface 5 with respect to its flow cross-sectional area in the direction of the feed 3 smaller. As explained above, this requirement leads to a very uniform fuel supply to the fuel surface 5 and thus to a very uniform combustion due to consideration of the volume compensation.
  • the flow-guiding element 6 is designed to be cone-shaped on the outside of the sleeve and at least in the area of the focal surface 5. Further, if the flow guide element 6 is also cone-shaped on the inside of the sleeve, this can even be formed as a whole of cone-shaped sheet metal material (see in particular FIG. 2 and 3 ). - Of course, however, other embodiments of the flow guide element 6 into consideration, as long as in these the sleeve outer space 8 is formed smaller in the direction of feed 3.
  • the feed side end of the flow guide element 6 has an outer diameter which corresponds to a feed side inner diameter of the burner body 1.
  • Spacers 9 are arranged. This in FIG. 2 Hatched spacers 9 are formed supporting on an inner side of the burner body 1. Furthermore, the spacer elements 9 are arranged as strip-shaped components for flow guidance at least in the region of the focal surface 5.
  • the six little dashes in FIG. 2 indicate the fixation points or lines (for example, by welding) for in this FIG. 2 at this circumferential positions not shown spacers 9 (the upper and lower spacer 9 is in FIG. 2 but shown; FIG. 3 shows four of the total six spacer elements 9).
  • the spacer element 9 forms an axial support of the flow guide element 6 against the closed end face 4. Between the flow guide element 6 or the spacer elements 9 and the end face 4 there is preferably only a punctiform contact area for minimizing the heat transfer (in each case).
  • FIG. 2 and 3 shows, when using a plurality of spacer elements 9 between these at the supply-remote end of the flow guide element 6, the sleeve interior 7 with the sleeve outer space 8 pneumatically connecting recesses 10 is provided. These serve to convey the gas-air mixture in cooperation with the curvature 13 as evenly as possible to a respective flow gap formed by two spacer elements 9, whereby at the same time the end face 4 is cooled.
